Abstract

An optical fiber cable management panel is provided with slideable drawers and structure within the drawers for cable management and/or connection to other devices. Tray inserts drop into the drawers to provide the appropriate management and connection devices. A movable take-up mechanism manages the cable entering and exiting the drawers at side openings. Stackable pivoting storage trays on the tray insert include a detent arrangement for holding each tray in a pivoted access position. The tray inserts further include a front key, and a back tab mounting arrangement for mounting the tray inserts to the drawers, and side radius limiters including notches for extending over raised portions of the drawer. The take-up mechanism includes a U-shaped trough section and cable retention tabs. A control mechanism is provided for controlling movement of the take-up mechanism relative to the drawer.

Claims

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

(a) providing a chassis having a drawer;

(b) routing an optical fiber cable into an interior of the chassis through an access opening of the chassis;

(c) moving the drawer, relative to the chassis, from a closed position wherein the drawer is fully inserted within the chassis to a intermediate position wherein the drawer partially extends outward from the chassis, and further to an open position wherein the drawer fully extends outward from the chassis;

(d) moving a radius limiter, in a synchronized manner relative to the drawer, from a first position on the drawer toward a second position on the drawer when the drawer moves from the intermediate position to the open position.

2. The method of claim 1, wherein the radius limiter remains stationary relative to the drawer when the drawer moves from the closed position to the intermediate position.

3. The method of claim 1, further including moving the drawer, relative to the chassis, from the open position, to the intermediate position, and further to the closed position.

4. The method of claim 3, further including moving the radius limiter, in a synchronized manner relative to the drawer, from the second position toward the first position when the drawer moves from the intermediate position to the closed position.

5. The method of claim 4, wherein the radius limiter remains stationary relative to the drawer when the drawer moves from the open position to the intermediate position.

6. The method of claim 1, wherein the radius limiter includes a trough section, the method further including placing the optical fiber cable into the trough section of the radius limiter.

7. The method of claim 6, wherein the radius limiter includes a tab located adjacent to the trough section, the method further including pivoting the tab to cover a portion of the trough section to retain the optical fiber cable within the trough section.

8. The method of claim 7, further including snapping the tab into slots formed in the radius limiter to secure the tab relative to the trough section.

9. The method of claim 1, further including moving the radius limiter at half-speed relative to a moving speed of the drawer.

10. The method of claim 9, wherein moving the radius limiter at half-speed is provided by a linear bearing arrangement including a wheel interconnected to the radius limiter, the wheel being in contact with both the drawer and the chassis.

11. The method of claim 1, wherein the step of routing the optical fiber cable through the access opening includes routing the optical fiber cable through the access opening located in a side of the chassis.
