Abstract

An optical fiber cable management panel includes drawer assemblies, each including a drawer slidable within a chassis. The drawer assemblies are secured together by a bracket that includes an interlock arrangement with the chassis. Such an interlock arrangement includes a non-threaded stud engaging a hole. Radius limiters may be part of the drawer assembly and include a cable entry aperture have a closed perimeter and a flared cable guide surface around most of, and preferably all of, the closed perimeter to allow for the entry of cables from all directions. A control mechanism controls movement of the radius limiter relative to the drawer assembly. The control mechanism includes a rotating member that has an axis of rotation transverse to the slidable motion of the radius limiter and normal to the radius limiter.

Claims

1. (canceled)

2. A method of managing cables, the method comprising the steps of:

a) providing a drawer slidably mounted to a chassis by a drawer slide;

b) providing a cable radius limiter located at one side of the drawer, the cable radius limiter being mounted to a control mechanism having a wheel with a horizontally oriented wheel diameter;

c) routing a cable within the curved cable trough of the cable radius limiter;

d) sliding the drawer relative to the chassis, the wheel of the control mechanism contacting both the drawer and the chassis and rotating about a vertical axis during the sliding movement of the drawer; and

e) moving the cable radius limiter at one-half the speed of the sliding movement of the drawer.

3. The method of claim 2, wherein the step of providing the cable radius limiter includes providing a cable radius limiter having a bell-mouth portion that leads into the curved cable trough.

4. The method of claim 2, wherein the step of routing a cable includes pivoting a cover of the cable radius limiter to a closed position to capture the cable within the curved cable trough.

5. The method of claim 4, further including latching the cover of the cable radius limiter in the closed position.

6. The method of claim 2, wherein the step of providing the drawer and chassis includes providing first and second drawers slidably mounted to first and second chassis by drawer slides, each of the first and second chassis being connected together by an interlocking arrangement.

7. The method of claim 2, wherein the step of providing the cable radius limiter includes providing the cable radius limiter mounted to a projection formed on the control mechanism, the projection extending through a longitudinal slot located at the one side of the drawer.

8. The method of claim 2, wherein the step of sliding includes sliding the drawer to an open position, the opening sliding movement being limited by a drawer catch that engages a stop member of the chassis.

9. The method of claim 2, further including routing a plurality of cables within the curved cable trough of the cable radius limiter.

10. The method of claim 2, further including limiting the bend radius of the cable routed within the cable radius limiter by directing the cable against a flared cable guide surface of the cable radius limiter.
