Optical fiber distribution system
An optical fiber distribution system including a rack and elements which populate the rack including fiber terminations. Each element includes a chassis and a movable tray. The movable tray includes a synchronized movement device for moving a cable radius limiter. The tray includes cable terminations which extend in a line generally parallel to a direction of movement of the movable tray. Each of the cable terminations are mounted on hinged frame members positioned on each tray. The cables entering and exiting the movable tray follow a generally S-shaped pathway.
1. An optical fiber distribution element comprising:
a chassis;
a tray slidably movable with respect to the chassis along a direction of movement, the tray defining a front end and a rear end;
a slide mechanism, which connects the movable tray to the chassis, wherein the slide mechanism includes a radius limiter which moves with synchronized movement relative to the chassis and the tray during slidable movement of the tray;
wherein the tray includes at least one frame member that defines a front end and a rear end, the frame member including a frame member hinge at the rear end of the frame member that is coupled to a tray hinge positioned at the rear end of the tray, wherein the frame member hinge and the tray hinge are configured to, and cooperate to, allow the at least one frame member to pivot with respect to the tray about an axis perpendicular to the direction of movement of the movable tray such that the at least one frame member can be pivotally lifted and a bottom of the at least one frame member can be accessed from the front end of the tray;
wherein a cable entering or exiting the movable tray is routed around the radius limiter.
2. The element of claim 1 , wherein the tray includes two frame members hingedly mounted for independent movement.
3. The element of claim 1 , further comprising a cable mount along a side of the chassis.
4. The element of claim 1 , further comprising a second non-movable cable radius limiter along a side of the chassis.
5. The element of claim 1 , wherein the radius limiter of the slide mechanism includes a rotatable portion that is configured to rotate rearwardly for cable management.
6. The element of claim 1 , wherein each frame member defines an array of adapters, each adapter defining ports for receiving connectors to be interconnected through the adapter.
7. The element of claim 6 , wherein the array of adapters defines a line which is generally parallel to the direction of movement of the movable tray.
8. The element of claim 1 , wherein the movable radius limiter defines a U-shaped configuration.
9. The element of claim 1 , wherein the cable entering or exiting the movable tray follows an S-shaped pathway as the cable extends from an exterior of the movable tray toward the movable radius limiter in a first direction, winds around the radius limiter in a second direction generally opposite the first direction, and is routed back within the at least one hingedly mounted frame member in a third direction generally opposite the second direction.
10. The element of claim 9 , wherein the S-shaped pathway includes an upper portion and a lower portion.
11. The element of claim 10 , wherein the radius limiter of the slide mechanism defines a divider for separating and guiding cables to and/or from the upper portion and the lower portion of the S-shaped pathway.
