Abstract

A fiber distribution frame includes a support structure having a wall with a plurality of bulkhead assemblies secured to the wall. Each of the assemblies has opposing and spaced-apart slide plates. A connector support rod is positioned between the slide plates. The rod is slidably connected to each of the slide plates for the rod to slide along a linear and horizontal path of travel extending substantially perpendicular to the wall. The rod is slidable between a retracted position and an extended position. In the retracted position, a rear end of the rod is positioned adjacent the wall. In the extended position, the rear end of the rod is positioned adjacent a forward edge of the slide plates. The rod carries a plurality of fiberoptic adaptors. Each of the adaptors may receive an individual coupled pair of fiberoptic connectors. The plurality of adaptors are disposed on the rod in a linear array extending along the path of travel. The adaptors are aligned for coupled connectors to extend transversely away from the path of travel on opposite sides of the rod. Snap clips are provided to mount each plate to the support structure. Each plate is further constructed from separate halves and includes a dove-tail arrangement between each plate and the rod. A stop limits the rod from sliding beyond the extended position. A flexible tab engages the stop, and also permits insertion and removal of each rod from the assemblies.

4. the rod carrying a plurality of fiber optic adaptors each for receiving an individual coupled pair of fiber optic connectors, the plurality of adaptors disposed on the rod in a linear array extending along the path of travel and with the adaptors aligned for coupled connectors to extend transversely away from the path of travel on opposite sides of the rod;

5. wherein the plates are spaced apart to define an unobstructed spacing between the plates on opposite sides of the rod along the length of the plates between the rear and forward edges;

6. a vertical lock slide between the rod and the plates wherein the rod is slideable only in the horizontal direction, and wherein the rod is locked to the plates in the vertical direction;

c. wherein the plurality of assemblies are disposed in a vertical array with an upper of the plates of an assembly concurrently being a lower one of the plates of an adjacent assembly.

2. A fiber distribution frame according to claim 1, wherein the plates are triangularly shaped, and the rod is positioned to generally bisect the triangular shape.

3. A fiber distribution frame according to claim 1, wherein the assemblies are grouped into multiple groups of multiple assemblies with a gap between groups.

4. A fiber distribution frame according to claim 3, further comprising fanning clips aligned with the gaps between groups.

5. A fiber distribution frame according to claim 1, further comprising two transversely spaced, vertical arrays of the assemblies.

6. A fiber distribution frame according to claim 5 comprising a field of cable storage members disposed between the two vertical arrays of the assemblies.

7. A fiber distribution frame according to claim 1, wherein the rod includes upper and lower dove-tail rails, and wherein the respective upper and lower plates each include a dove-tail groove, wherein the dove-tail rails and the dove-tail grooves define the vertical lock slide.

8. A fiber distribution frame according to claim 7, wherein each plate includes two separate slide plate segments, each segment including a locking tab engageable with the other segment, each segment forming a portion of the dove-tail groove.

9. A fiber distribution frame according to claim 8, wherein each slide plate segment of each plate is identical to the other segment of the respective plate.

10. A fiber distribution frame according to claim 9, further comprising a stop extending from the rod adjacent to the rear end, each slide plate segment including a tab adjacent to the forward edge and engageable with the stop so as to define the extended position, each slide plate segment including a snap clip, and a fastener receiving vertical plate, the vertical plate including a hole for receiving a fastener, the support structure including a first opening receiving the snap clip, and a second opening for receiving the fastener, and further comprising a fastener positioned in the hole of the vertical plate and the second opening of the support structure.

11. A fiber distribution frame according to claim 10, wherein the tab includes a ramped surface facing the forward edge, wherein the tab further includes a flexible portion extending generally parallel to a plane defined by the plate.

12. A fiber distribution frame according to claim 1, further comprising a stop extending from the rod adjacent to the rear end, the plate including a tab adjacent to the forward edge and engageable with the stop so as to define the extended position.

13. A fiber distribution frame according to claim 12, wherein the tab includes a ramped surface facing the forward edge, wherein the tab further includes a flexible portion extending generally parallel to a plane defined by the plate.

14. A fiber distribution frame according to claim 1, wherein the rear edge of the plate includes a snap clip, and a fastener receiving vertical plate, the vertical plate including a hole for receiving a fastener, the support structure including a first opening receiving the snap clip, and a second opening for receiving the fastener, and further comprising a fastener positioned in the hole of the vertical plate and the second opening of the support structure.
