BACKGROUND

Connection systems or other interconnection systems are normally used in communication networks in order to make the implementation of logical communication links more flexible. An example of a patch or patch system is a patch panel. Typically, a patch panel includes a panel in which a variety of ports are formed or contained. Each port includes a "front" connector (or other connecting mechanism) and a "rear" connector (or other connecting mechanism such as a punchblock or permanently attached fiber optic). The port is configured to communicate communicatively any cable attached to the front connector of said port with any cable attached to the rear connector of said port. Other connection systems are implemented in a similar way.

Many types of physical layer management (PLM) systems have been developed in order to automatically keep track of which cables are connected to which ports in a patchwork. In one type of system,

ΙΝΠ · Τ »· Ε |_Λ1 Each connector attached to a front connector on a patch panel has a radio frequency identification (RFID) tag. Then, it is possible to use an RFID reader to wirelessly read an identifier from the RFID tag of each front connector to keep track of which connectors and cables are attached to the front connectors on the patch panel. Usually, an RFID reader is integrated into the patch panel to read such front RFID tags. However, such systems do not include any mechanism to monitor the rear connectors or cables. Also, the connectors used with such systems to implement the ports are usually not removable.

The adapter 100 is configured to be inserted into a printed circuit board (PCB) 138 which may be attached to or a part of the patch panel system 104. Said PCB 138 is also referred to herein as panel PCB 138. Panel PCB 138 is supported by a rack 137 or other support structure (for example, a support structure integrated into an enclosure 139 containing the patch panel system components 104).

The panel PCB 138 includes openings 14 0 into which a respective adapter 100 is inserted. These openings 140 are also referred to herein as ports 140 of the patch panel system 104. The panel PCB 138 includes boards with edge plates 142 at the top and bottom of each opening 140. These plates 142 are also referred to herein as panel plates 142. The panel boards 142 are used to provide two connections between the panel PCB 138 and the adapter PCB 136 of the adapter 100 that is inserted into said opening 140. This is done with two fasteners 144. The fasteners 144 are configured to hold in place. corresponding adapter 100 into opening 140 when inserted into

the opening 140. An upper part of the adapter 100 and the fastener 144 are used on the other side of the fastener 144, at the bottom of the adapter 100.

In addition, each fastener 144 is configured to establish an electrical connection between the panel boards 142 on the panel PCB 138 and the adapter boards 130 on the adapter PCB 136. The fasteners 144 may be fabricated, for example, from metal or a plastic with metal inserts. The fasteners 144 can be produced in other ways. Each of the panel boards 142 on the panel PCB 13 8 is configured to contact the spring-loaded portion of one of the fasteners 144 when the adapter 100 is inserted into an opening 140 on the panel PCB 138. This results in two signaling paths between each adapter PCB 136 and panel PCB 138. In this exemplary embodiment, the other portion of each fastener 144 has a 90 degree fold such that that portion aligns with a plate adapter 13 0 on the adapter PCB 13 6 by spring pressure or other connection measures, and establish an electrical connection with the adapter.

As described below, it is possible to use a

Antenna coils 126 can be shaped on either the outer surface or the inner surface of an adapter PCB 136 (with described components or PCB reading) or on the adapter PCB 136. In this example mode, it is shaped to adapter boards 13 0 on adapter PCB 136 on adapter PCB outer surface

The adapter PCB 136 may be attached to the side of the adapter 100 in a recess, clamped to the body of the adapter 106, molded into the body of the adapter 106, or with another type of fit. Components may also be encapsulated, especially if adapter PCB 136 is molded into adapter body 106 or for environmental reasons. Alternatively, the components can be located internally on the adapter PCB 136 by various production or assembly techniques.

The coils of the antenna 126 of multiple adapters 100 and ports 140 are communicatively coupled to a REID reader 132 attached to the PCB of panel 138. Additionally, LEDs 128 of multiple adapters 100 and ports 140 are communicatively coupled to a single LED controller 134 attached to panel 138. LED controller 134 is configured to turn LEDs 128 on and off (eg, as a visual cue to a technician regarding the execution of an electronic work order). More specifically, in the example

<img file="MX346642B_D0016.tif" />

1A-1F, the mode illustrated in Figures is coupled to the pickup coils 126 of all the adapters 100 and ports 140 to the same RFID reader 132, and the LEDs 128 of all the adapters 100 and ports 140 are coupled to the same LED driver 134. However, in other exemplary embodiments, it is possible to use more than one RFID reader and LED driver, and multiple adapters 100 and ports 140 are communicatively coupled to each RFID reader and each LED driver.

In the embodiment shown in Figures 1A-1F, a multiplexer 146 attached to panel PCB 138 is used to selectively couple RFID reader 132 and LED driver 134 to adapter PCB 13 6 for one of the adapters 100 inserted into panel 104. In addition, a system controller 150 is attached to panel PCB 13 8 and communicatively coupled to RFID reader 13 2 and LED driver 134.

The circuitry in each adapter PCB 136 is coupled to the multiplexer 146 with two respective lines used both to couple the antenna coils 126 for said adapter PCB 136 to the RFID reader 132 and to couple the

IMPI

<img file="MX346642B_D0017.tif" />

LED 128 for said adapter PCB 136 to driver LED 134.

In this example, the LED controller 134 controls the LEDs 128 with direct current (DC) signals, while the RFID reader 132 obtains information from the RFID tags 102 inserted in said adapter 100 (through the pickup coils 126 ) using radio frequency (RF) alternating current (AC) signals. The circuitry in each adapter PCB 136 includes suitable filter components that isolate the DC signals used to control the LEDs 128 and the AC RF signals used to obtain information from the RFID tags 102 from each other.

An XY array is used to selectively couple multiplexer 146 to the adapter PCB 136 of one of the adapters 100. In this example, all adapters 100 in each row of panel 104 share a common row 152 connected to an input terminal. and output (I / O) of the respective row of multiplexer 146. Additionally, all adapters 100 in each column of panel 104 share a common column 154 connected to an input and output (I / O) terminal of the respective column of multiplexer 146. As controlled by system controller 150, the multiplexer 146 is capable

154 to which it is connected) to RFID reader 132 and LED controller 134. This causes adapter PCB 136 of adapter 100 located in the selected row and column to couple to RFID reader 132 and LED controller 134. The number of control lines in patch panel system 104 is greatly reduced by using the same lines in XY array to couple the antenna coils 126 to the RFID reader 132 and to couple the LEDs 128 to the LED driver 134.

As illustrated in Figure 1E, in this exemplary embodiment, panel boards 142 for each port 140 are produced on panel PCB 13 8 at the top and bottom of the corresponding opening 140. For each port 140, one of the Plates 142 terminate row 152 for said port 140 and other plates 142 terminate column 154 for said port 140.

In the example illustrated in Figures 1A-1F, the body 106 of each adapter 100

In an exemplary embodiment, lines 152 and 154 are formed on or on the panel PCB 138. Lines 152 and 154 are visible in Figure 1F for ease of illustration. However, in one implementation, the panel PCB 13 8 is produced to look like a conventional metal panel used in conventional patch panels by painting (or otherwise covering) the panel PCB 138 (and lines 152 and 154 in it) with a color of the type of color used in conventional metal panels.

Each RFID tag 102 stores a unique identifier of the connector 108 and / or associated cable 110. Said identifier can be used to identify which cable 110 is attached to each port 140 of patch panel 104. In some implementations, RFID tags 102 are used to store other information and / or in addition to being read, it can be written to they. As usual,

IMPI rwmw&gt; mexican delaewtwm ^ Each RFID tag 102 includes a non-volatile memory used to store such information and RFID transponders to allow the RFID tag 102 to be activated by the RFID reader 132 and communicate with it.

The information read from RFID tags 102 can be used for various PLM related purposes. For example, information read from RFID tags 102 can be communicated to a central management system 158 that monitors which cables are attached to patch panel 104. Information read from RFID tags 102 can be communicated to management system 158 in various ways (eg, via a wireless network connection, wired network connection, or removable media).

Additionally, the information read from the RFID 102 tags can be used to assist a technician in complying with a work order that, for example, involves moving, adding, or otherwise changing a connection established in the panel system. number of connections 104. For example, it is possible to download the information related to a work order to be executed on a mobile communication device 160. The software executed on the

The information read from the RFID tags 102 can be used to identify a particular connector 108 that will be affected by one of the steps necessary to fulfill a work order. In addition, the information read from an RFID tag 102 after one of the necessary steps of a work order has been performed can be used to confirm that that step was performed properly.

The information read from RFID tags 102 can also be used for other purposes.

Also, in this exemplary embodiment, antenna coils 126 are implemented as a single common loop (illustrated in Figure 1A-F). When the RFID reader 132 is selectively coupled to the antenna coils 126 for a particular port 140 in the system or connection panel 104 through the multiplexer 146, the RFID reader

RFID 132 is capable of reading an RFID tag 102 attached to both connectors 108 (i.e. front and rear) that are inserted into adapter 100 or any RFID tag 102 attached to a protective cover that is inserted into adapter 100.

To that end, the RFID reader 132 transmits a radio frequency (RF) signal suitable to activate any RFID tags 102 attached to any connectors 108 or a protective cap inserted into the target adapter 100 and, in response, cause the tags to RFID 102 (if any) transmit at least a part of the information that is stored in them. One way to do this employs standard RFID anti-collision protocols that standard RFID tags implement in response to situations where multiple RFID tags try to transmit at the same time.

With this approach, to read the RFID tags 102 attached to both connectors 108 attached to a given adapter 100, the RFID reader 132 is configured to transmit the RF interrogation signal and wait for the receipt of response transmissions from the tags. RFID 102 associated with both

With this approach, the time-out period during which the RFID reader 132 waits for the receipt of transmissions should be long enough to allow the RFID tags 102 on both sides of the adapter 100 to transmit their information in the situation in the one with the longest possible delay with the standard RFID anti-collision protocol. In addition, the RFID reader 132 is configured to wait before signaling to the technician that the read transaction is complete.

One problem with this approach is that standard RFID anti-collision protocols can make such read transactions take too long.

Another approach employs Application Family Identifiers (AFIs) defined according to ISO RFID standards. In general, when AFIs are used, RFID tags are configured to respond only to a single particular type of RFID interrogation signal (ie, an RFID interrogation signal that includes an AFI byte with a particular value). This is done to read multiple

INSTITUTO MEXICANO DE LA IMTIEDAD INDUSTRIAL RFID tags 102 so that it is faster than the application of the standard RFID anti-collision protocol.

For example, it is possible to use three different AFI values. It is possible to assign a first AFI value to RFID tags 102 attached to connectors 108 inserted at the rear of patch panel system 104. A second AFI value can be assigned to RFID tags 102 attached to connectors 108 inserted in the front of patch panel system 104 and a third AFI value can be assigned to RFID tags 102 attached to protective caps inserted into the front of patch panel system 104. If an RFID tag 102 attached to a protective cap is read (which is determined by the AFI value), this indicates that the front of the associated adapter 100 is not in use. That is, if the front of an adapter 100 has a protective cap (determined by reading the RFID tag 102 attached to the protective cap), the front of that adapter 100 is considered unused.

In the embodiment example described above with reference to Figures 1A-1F, connectors and

In such an exemplary embodiment, the optical adapter 100 is configured so that it can be removed and inserted back into the patch panel system 104. Additionally, in this exemplary embodiment, the optical adapter 100 and antenna coil pair 126 are configured to read a REID tag 102 attached to a connector 108 inserted on a first (eg, front) side of the optical adapter 100 and to read an RFID tag 102 attached to a connector 108 inserted into a second (eg, rear) side of the optical adapter 100.

Figure 2A illustrates an example optical adapter 200 that includes an adapter body 201 with parallel sides 204, 205 and parallel ends 206, 207 extending between a front portion 202 and a rear portion 203 (see Figures 2B and 2E). . In certain implementations, the sides 203, 204 form major surfaces of the adapter body 201 and the ends 206, 207 form minor surfaces of the adapter body 201. The adapter body

201 defines a first opening 208 in the front 202 and a second opening 209 in the rear 203. Each opening 208, 209 is configured to receive a plug connector. Openings 208 and 209 are also referred to herein as connector openings 208 and 209.

A connector retention arrangement 250 is attached to the adapter body 201 to hold the pin connectors in the connector openings 208, 209. For example, the connector retention arrangement 250 may include flexible fingers that engage the outer bodies of the connectors. pin connectors. In certain implementations, the connector retention arrangement 250 is configured to receive and align the sockets of the pin connectors. In one example, the connector retention arrangement 250 includes a flange 251 configured to be contained in a slot 252 defined in the body of the adapter 201 to secure the connector retention arrangement 250 to the adapter 200 (see Figure 2E).

An example of a 22 0 circuit arrangement is located on a first side 204 of the first adapter body 201. For example, the first side 204 of the adapter body 201 may define a

IMPI

INSTITUTO MEXICANO OElATMfUMD INDUSTRIAL hole 216 of adequate size to contain a circuit board 222. The body of adapter 201 includes one or more pins 217 that extend outwardly from hole 216. Circuit board 222 defines one or more openings 225 of size to fit pins 217. Accordingly, the pins 217 help to align the circuit board 222 in the body of the adapter 2 01 and to keep the circuit board 222 in the body of the adapter 201.

Circuit board 222 includes two contact plates 224 at one end of circuit board 222. At least one RFID antenna coil 22 6 is also attached to circuit board 222. For example, the RFID antenna coil 226 may be attached to a central region of circuit board 222. In certain implementations, a visual indicator 228 (eg, a light source such as a light-emitting diode) is attached to circuit board 222. For example, the visual indicator 228 can be attached to an opposite end of the circuit board 222 relative to the contact plates 224. In the particular example illustrated in Figures 2A-2I, the visual indicator 228 is implemented with an LED 228 and the visual indicator is also referenced ²⁷ iMTTnnpjuüuawo:

Adapter body 201 defines an aperture 255 (Figure 2E) that can be accessed from inside the first connector opening 208. The LED 228 is positioned in the opening 255 so that the light emitted by the LED 228 enters the first connector opening 208. Accordingly, LED 228 can illuminate any light-transmitting material located in connector opening 208 (eg, on a pin connector that can be placed in connector opening 208).

In some implementations, a cover 218 is placed on the circuit board 222 (for example, see Figure 2B). For example, the cover 218 can be overmolded to the adapter body 201 on the circuit board 222. In other implementations, the cover 218 can be hooked, welded, or otherwise attached to the adapter body 201. The cover 218 inhibits the damage to circuit board 222 and to components attached to it. In certain implementations, cover 218 includes cutouts or gaps that align with contact plates 224 which allow contact plates 224 to remain uncovered. In others

The adapter body 201 includes partition tabs 210 that extend outwardly from the ends 206, 207 of the adapter body 201. For example, the partition tabs 210 may extend outwardly from the intermediate end sections 206, 207. The tabs dividers 210 simplify maintaining the adapter body 201 with a panel 300 and another surface (see Figure 2H). For example, it is possible to position one or more fasteners 230 on the body of the adapter 201. Each fastener 230 includes a fastener body 231 configured to attach to the body of the adapter 201. In some implementations, a majority of the body of the fastener 231 extends into one of the ends 2 06, 207 of the adapter body 201.

The body of the fastener 231 has at least a first contact section 232 that flexibly extends outward from the body of the adapter 201 when the body of the fastener 231 is attached to the adapter 200. When the rear 203 of the adapter 200 is inserted through

232 of fastener 230 passes through aperture 305 and engages a rear portion 301 of panel 300. Consequently, panel 300 is held between first contact section 232 of fastener 23 0 and partition flange 210 of adapter 200.

In some implementations, clip 230 also electrically connects adapter 200 to the circuit attached to panel 300 (eg, see Figure 2H). In such implementations, the fastener 230 includes a second contact section 234. The second contact section 234 is configured to extend over one of the contact plates 224 of the circuit board 222. The second contact section 234 is electrically connected to the first contact section 232. For example, the bra body 231 can be produced from an electrically conductive material (eg, metal). The first contact section 232 may be linked to a contact plate 302 provided at a rear end 301 of the panel 300 when the adapter 200 is attached to the panel 300 (see Figure 2H). Consequently, the components on the circuit board of the adapter 200 can be electrically coupled to the circuits

In some implementations, the fastener body 231 also includes a third contact section 236. The third contact section 236 extends into the first contact section 232. When the adapter 200 is attached to the panel 300, the third contact section 236 of fastener 230 is configured to engage with a front 303 of panel 300. For example, the third contact section 236 may be linked to a contact plate 304 provided on the front 303 of the panel 300 (see Figure 2H). In certain implementations, contact plate 3 04 at the front 3 03 of panel 300 is electrically connected (for example, through 3 06) to contact plate 3 02 at the rear 301 of panel 300 (see Figure 2H).

The combination of the second and third contacts 234, 236 increases the probability that some part of the body of the fastener 231 will come into contact with one of the contact panel plates 302, 304 when a pin connector is placed in one of the openings for connectors 208, 209. For example, inserting a pin connector into the

In such situations, the third contact section 236 will move against the front contact plate 304 on the panel 300 and the connection between the circuit board 222 and the circuit panel will be maintained. Also, inserting a pin connector into the rear connector opening 209 or removing a pin connector from the front connector opening 208 may move the third contact section 236 away from the front contact plate 304 on the panel 300. bra 230.

The cantilever arm 233 bends or bends so that the second contact section 234 bends. extends generally orthogonal to the flat section of the body of the fastener 231. Accordingly, the second contact section 234 is configured to lie on one of the major surfaces (eg, the first side 204) of the adapter body 201. A distal tip of the second contact section 234 can be curved to facilitate contact. with the contact plate 224 of the circuit board 222.

The third contact section 236 is arranged in a

The second cantilever arm 235 bends or curves such that a portion of the third contact section 234 extends generally orthogonally. relative to the flat section of the fastener body 231 and to the second contact section 234. The third contact section 236 defines a flexible section so that the distal tip can move towards the second cantilever arm 235 and away from the first contact section 232. In the illustrated example, the distal tip of the third contact section 236 defines a protruding curve or bulge toward the first contact section 232.

The body of the fastener 231 defines a retention flange 238 that facilitates the positioning of the body of the fastener body 231 on the body of the adapter 201. The retention flange 23 8 is positioned on the opposite side of the body of the fastener 231 with respect to the third contact section 236. Retaining flange 238 curves away from the flat section of the fastener body 231. The flat section of the fastener body 231 defines a notched section

With respect to Figures 2A and 2B, the body of the adapter 201 is configured to be fitted with one or more of the fasteners 230. For example, the ends 206, 207 of the body of the adapter 201 define recesses 212 in which it sits. the flat section of the fastener body 231. The end recesses 212 form projections that extend at least partially around the end recesses 212. For example, a protrusion 215 may be formed along the second side 205 of the adapter body 201 and at the opposite end of the gap 212 from the partition flange 210. The fastener body 231 is positioned in one of the recesses 212 so that one side of the fastener body 231 and the retaining flange 238 are contiguous with the protrusion 215. The body of the adapter 2 01 includes a retainer 214 that extends over and engages the notched section 239 of the body of the fastener 231, opposite the projection 215.

The adapter body 201 defines the cutouts 213 in the first side 2 04 that connects the gaps 212 with the gap side 216. The first cantilever arm 233 of each fastener

230 extends through one of the cuts 213 so that the second contact section 234 of the fastener 230 can couple the contact plate 224 to the circuit board

222. In some implementations, the dividing tabs 210 define the gap sections 211 in which the third contact sections 236 of the fasteners 230 can be seated. In other implementations, the third contact section 236 of each fastener 230 can abut against a outer surface of the respective partition flange 210.

With respect to Figures 2E-2G, the plug connectors can be inserted to mate with adapter 200 in a specific direction of rotation. For example, the adapter body 201 may define a key 219 in the connector openings 208, 209 that are configured to mate with the corresponding wedges on the pin connectors when they are placed in the connector openings 208, 209. In the example shown, keycaps 219 are provided on an opposite side of the adapter body 201 from the circuit board 222. In the example shown, the second side 205 of the adapter body 201 defines keypads 219. In the example shown certain implementations,

Keyways 219 are provided on a side opposite the adapter body 201 from the LED 228.

In accordance with some aspects of the description, adapter 200 may also include a wedge arrangement 240 for mounting adapter 200 on panel 300 in a specific direction of rotation. For example, in some implementations, panel 300 can be configured to have multiple adapters 200 fitted to it and each adapter 200 is inserted in a specific direction of rotation. In certain implementations, the direction of insertion of some adapters 200 may differ from the direction of insertion of other adapters 200 with respect to panel 300. In other implementations, adapters 200 can be inserted into panel 300 so that the keyways 219 of the adapter bodies 201 are facing in the same direction with respect to the panel 300.

In the example shown in Figures 2E-2G, the wedge arrangement 240 includes a rail 241 that is configured to slide in a notch 308 defined in the panel 300 (Figure 21). In some implementations, panel 300 defines one or more apertures 305 that are sized³⁷ IMPI®

In other implementations, panel 300 defines one or more apertures 3 05 that are sized to fit place a single adapter 200 in each. In such implementations, each opening 305 defines a notch 308. In still other implementations, the panel 300 may define a protruding protrusion at the opening 305 and the body of the adapter 201 may define a channel along which the protrusion can slide when the adapter 200 is mounted to the panel 300.

In some implementations, rail 241 defines an inclined or conical surface 243 that leads rail 241 for the keys to the notch in panel 308 where adapter 200 is mounted to panel 300 (see Figure 2G). Tapered surface 243 facilitates insertion of keyway rail 241 into panel notch 308.
