Detailed description of the embodiments

Referring to Figures 1 to 3, an explanatory example of a support or frame 20 for splicing, terminating and managing fiber optic cables within the frame is shown. Also, other features of frame 20 are shown in Figures 4-13. An upper portion 22 of frame 20 defines a storage and termination area. A lower portion 24 of frame 20 defines a splice area. Cables containing one or more individual optical fibers are typically introduced into frame 20 from an overhead cable environment through an upper side 26 of frame 20, or from a raised floor environment of base 28 of frame 20. Si the cables are pre-terminated, the cables run directly to the termination and storage area 22. If the cables entering the frame 20 are not pre-terminated, the cables are extended to the splice area 24 for splicing with terminated cables. From the splice area 24, the cables then extend to the termination and storage area 22. In the termination and storage area 22, a plurality of accessible termination locations are provided for the terminated cables and for connecting other cables to terminated cables, such as cords or patch cords. By using patch cords, telecommunications equipment can be interconnected between termination sites through frame 20.

Curved guides 101 protect cables extending from splice area 24 to storage and termination area 22. Center cover 102 prevents stored patch cords from hanging down from internal management panel of bracket 40 within splice area 24. Cutouts 104 at each end of horizontal tray 50 can be filled with horizontal brackets for support horizontally extending cables, or downward curved brackets, if cables are routed directly downward from frame 20. The horizontal cable tray 50 also includes a front wall 105, and a rear wall 106 extending from the main horizontal portion.

Referring now to Figures 4 to 10, each termination module 32 includes a top side 110, a base 112, opposite sides 114, 116, and a rear side 118. The illustrated module 32 is from the right set 36. Preferably, each one of the termination modules 32a, 32b, are identical, but are positioned in an inverted orientation. Therefore, the top side 110 and the base 112 would be in the reverse orientation for the left set 34 of modules 32.

Each termination module 32 defines an open front side 120 preferably closed by a smaller first door 122 and a larger second door 124, both of which are hingedly mounted to a remainder of the termination module 32 about vertical axes. First door 122 defines a cable access door, especially useful for allowing cables to enter termination module 32 and for positioning cables passing between locations on frame 20, such as cable running between the area splice 24, and an upper termination module 32 positioned on the particular termination module 32. The cable access door 122 is rotatably mounted to the side 114 via a hinge 126.

The second door 124 defines a main panel 124 and is rotatably mounted to the side 116 via a second hinge 128. The main panel 124 includes a plurality of rows 130 of openings 132, each dimensioned to support an adapter 134. Each of the adapters 134 includes at least two aligned openings, one on a front side 134a, and the other on a rear side 134b for holding two connectors 142 for optically connecting the connectors and cables connected to the connectors. Various adapters 134 can be used, including an adapter of the type shown in US Patent No. 5,317,663 constructed to have the normally known SC configuration for receiving an SC connector at each end. Other styles of adapters / connectors can be used, including ST, FC, E-200, and other styles. Preferably, main panel 124 includes six upper rows 130 of eight openings each, and six lower rows 130 of eight openings each. If desired, fewer than eight of the openings can be used for a given application. In the illustrated embodiment, the adapters 134 are spring-mounted to the main panel 124 with a clip 135. Designation tapes (not shown) may be provided to label each of the openings 132.

Rear connectors 142b are connected to cables leading into frame 20 from telecommunications equipment. A rear side 140 of main panel 124 is used primarily as a semi-permanent connection between connectors 142b and adapters 134. A front side 138 of main panel 124 defines a plurality of accessible termination locations that can be connected to one another with patch cords and connectors 142a, in order to interconnect telecommunications equipment.

Main panel 124 includes a corner side panel 143. Side panel 143 includes a vertical set of clips 144 adjacent to each row 130 of openings 132. Clips 144 rotate with main panel 124 and side panel 143. Each clip 144 supports the wires of each connector 142 arranged in each row. From clips 144, the cables extend through a side access of each cable guide 60, 62. Clips 144 help retain and protect cables when main panel 124 is rotated. Without clips 144, rotation of main panel 124 can stretch or push excessively on portions of cables positioned within cable guides 60, 62.

Main panel 124 further includes upper and lower hinge plates 146, 148. A ceiling plate 150 and base plate 152 define the upper side 110 and base 112 of termination module 32 and each includes a hinge plate portion 154 , 156, which cooperates with the hinge plates 146, 148 to rotatably mount the main panel 124 to the ceiling and base plates 150, 152. Each of the hinge plate portions 154, 156 includes a stop 158, 160 to limit rotation of the main panel 124.

The main panel 124 is disposed at an angle with respect to a vertical plane that extends parallel with respect to a front side and a rear side of the frame 20. Such angulation allows an increased density on the adapters 134 arranged with the longitudinal axes transversely with with respect to the front and rear planes. Furthermore, cable management is facilitated by angulation of the cables towards the cable guides 60, 62. For the right set 36 of modules 32, the main panels 124 are angled towards the right side of the frame 30. For the left set 34 of modules 32, the main panels 124 are angled towards the left side of the frame 30.

ES 2 278 632 T3

To maintain the main panel 124 in the closed position, as shown in Figures 1-5, two latches 162 are provided. Each latch 162 engages a flange 164 extending from the base and ceiling plates 150, 152. Cable access door 122 is also held in the closed position shown in Figures 4 and 5 by a second latch 166, which engages an edge 168 of main panel 124. Cable access door 122 also overlaps edge 168. Base and ceiling plates 152, 150 include cable passages 170, to allow vertical passage of cables into, and through termination module 32, if desired.

Referring now to Figures 6 through 10, internal cable management features are provided within the termination module 32. A cable clamp 182 securely holds a cable that is inserted into the termination module 32. A tab Bottom 181a helps maintain cable in passage 170. Flange 181a also maintains other cables passing through module 32 in passage 170. An intermediate flange 181c and a top flange 181b are also provided to position the desired cables in passage 170. From clamp 182, individual fibers are routed through a cable transition area 171 that includes various cable guides including tabs, spools, clips or rings. A tie bracket 190 can be used with or in place of the clamp 182 (see Figures 9 and 10) to secure the cable leading into the termination module 32. On the rear side 140 of the main panel 124, a tray Rear 192 is positioned centrally on main panel 124 projecting horizontally and rearwardly. Rear tray 192 includes a plurality of horizontal cable rings 194. A curved edge 196 helps prevent rear tray 192 from priming on cables positioned within an interior of termination module 132, vertical cable passage 170, or cable transition area 171.

As shown in Figure 8, an example cable 184 containing multiple fibers enters termination module 32 through base plate 152 at passage 170. Clamp 182 holds cable 184. A first fiber 184a extends around upper spool or guides 186a, passes through intermediate guides 186b, and around lower spool or guides 186c, around lower corner guide 186d to lower ring 188b, through horizontal ring 194 to one of the top points of the main panel 124. The second example fiber 184b extends around the upper guides 186a, passes through the intermediate guides 186b, around the lower guides 186c, back up through the intermediate guides 186b, around the upper guides 186a, around the upper corner guide 186e and through upper ring 188a. From the upper ring 188a, the second fiber 184b passes through the horizontal ring 194 to a lower point of the main panel 124. All of the adapters 134 of the main panel 124 can be connected to individual fibers that enter the termination module 32. For additional termination modules mounted to the frame 20, mounted on the termination module 32, the cables will pass through the modules lower termination modules to reach the upper termination modules in step 170. In use, the left assembly 34 of the frame 20 can be used to terminate the cables entering the construction. The right set 36 can be used to terminate the cables connected to various telecommunications equipment inside the building. The front portions of each termination module 32 are used to route the patch cables from the left side to the right side to interconnect the various rear termination locations. The connection cables pass under the internal management panel of the bracket 40. From each front connector point, the connection cables are inserted into one of the cable guides 60, 62 for vertical management of the connection cables. From a lower end of cable guides 60, 62, cables pass horizontally to the other side of frame 20, to the internal management panel of bracket 40, or to other frame or other equipment.

The front side 1202 of the connector module includes a plurality of adapters 134 for receiving connectors 142a from the patch cables. Corner retainers 362 hold each adapter 134 so that its longitudinal axis is at a non-transverse angle to the plane defined by front side 1202. In rear notch 1216, side segment 1230 of housing 1201 provides a mounting surface. for 134a rear adapters. Each rear adapter 134a receives a rear connector 142b for cables from step 970. Rear retainers 1240 secure each rear adapter 134a to housing 1201. Rear fitting on retainers 1240 allows for convenient assembly, and removal if necessary. The 134,134a adapters can be SC type (as shown), FC type, ST type or others. Side boss 1228 extends from major side 1206. If connector module 1200 is used on the left side 932 for a termination module 940 on the left side, the connector module 1200 is flipped over to have its front angle toward the right side 934 of frame 920. A side segment Corner 1231 connects side 1210 to side segment 1230.

Disposed within the housing 1201 of the connector module 1200 are one or more couplers 1242, such as splitters, combiners, wave division multiplexers, etc., to connect between the rear adapters 134 and the front adapters 134. In the As an example of Figures 57 and 58, 1x2 splitters are provided for couplers 1242. Rear internal connectors 1244 and fibers 1246 connect to couplers 1242. From the couplers 1242, other fibers 1248 connect to other forward internal connectors 1250 on the forward adapters 134. Connectors 1244, 1250 are connectors similar to connectors 142a, b. A collector bracket 1260 may be provided as desired to secure the collectors 1242 in place. Fiber management guides 1262, 1264 may be provided as appropriate to secure fibers 1246, 1248 in position. In the example shown, fibers 1246 follow an S-shaped path, followed by a loop-shaped path before connecting to couplers 1242, and fibers 1248 follow a loop-shaped path.

By providing a rear notch 1216, the connectors 142b extending from the rear adapters 134a along an outer side of the housing 1201 are shielded and do not penetrate the central passage 970 of the frame 920. In addition, notch 1216 also allows for a larger front panel surface area, as well as greater volume within the housing 1201 to route fibers from the rear adapters 134a to the collectors 1242 and then to the front adapters. 134.

Referring now to Figures 59 through 61, a second preferred embodiment of frame 1320 is shown with three termination modules 632 on the left side, one termination module 940, one column

Other cable guides 1234 and the walls 1236 of splice trays 244 they are added to assist with cable management in vertical cable guides 960, 962. Figures 59 through 61 further illustrate the variety and versatility of the various frames of the present invention.

Referring now to Figures 62 through 65, a modified preferred embodiment of a frame 1420 is shown. Termination module 1440 includes space for fewer connector modules 1200 (ten instead of twelve) relative to termination module 940. Only upper and lower guides 1056a, b are provided allowing greater access to rear adapters 134a and rear connectors 142b. Additionally, module 1440 cannot be passed to the left side of frame 1420. A mirror image of module 1440 would have to be constructed with notches 1030 appropriately configured to receive connector modules 1200 inverted so that they would fit on the left side of frame 1420.

Referring now to Figures 66 to 76, modified preferred embodiments are shown for a termination module 1540 and connector modules 1600, 1700. Instead of flat shelves 1050 as in termination modules 940, 1440, it is provided a vertical set of longitudinal guides or rails 1560. The rails 1560 provide additional interior space within the termination module 1540 relative to the shelves 1050. The connector module 1660 is similar in many respects to the connector module 1200. The lateral protrusion 1228 is received in one of the notches 1030 of the termination module 1540. A second lateral protrusion 1620 is provided from the larger side 1618 to cooperate in such a manner. slide with one of the 1560 rails, to mount and hold the 1600 connector module on the 1540 termination module.

By using longitudinal rails 1560, instead of the larger flat shelves 1050, connector modules of different heights can be conveniently used, if desired. For example, a modified connector module 1700 of Figures 73 to 76 may be used in termination module 1540, where two rows of openings 1703 are provided in front face 1702. Side boss 1720 is received on one of the rails 1560 (1560a in Figure 66). With the 1700 connector module having double, triple, quad, etc. height, not all 1560 rails are used. However, due to the low profile provided by the 1560 rails, 1700 multi-height connector modules are easily used in the 1540 termination module.
