Abstract

A fiber optic telecommunications frame is provided including termination modules positioned on left and right sides of the frame. The frame further includes left and right vertical cable guides. The frame includes a horizontal passage linking the left and right panels and the cable guides. The termination modules hold fiber optic modules with front termination locations. The fiber optic modules can house couplers, such as splitters, combiners, and wave length division multiplexers. A retention mechanism retains each fiber optic module in a partially removed position from the termination module.

Claims

1. A fiber optic termination module comprising:

a housing having first and second spaced apart ends, and first and second spaced apart sides extending between the ends, the housing including a rear extending between the first and second ends and the first and second sides to define an interior, the housing defining an open front, the first and second ends extending generally horizontally when the termination module is mounted to a telecommunications rack, the first and second sides extending generally vertically when the termination module is mounted to the telecommunications rack;

a plurality of longitudinal guides positioned in the interior of the housing for slideably receiving a plurality of fiber optic modules through the open front;

at least one adapter mounted to the housing, the adapter being configured to receive a fiber optic connector;

a spring biased ball plunger arranged on the housing, the spring biased ball plunger being configured to exert a retention force on a fiber optic module to retain the fiber optic module in a partially removed position with respect to the housing against a force sufficient to remove the fiber optic connector from the adapter.

2. The fiber optic termination module of claim 1, wherein the first side includes a vertical array of extensions for supporting cables extending toward the front opening.

3. The fiber optic termination module of claim 1, wherein the open front is positioned at a non-perpendicular angle relative to the rear, the sides positioned at a generally perpendicular angle relative to the rear.

4. The fiber optic termination module of claim 1, wherein the longitudinal guides are configured to receive planar flanges of the fiber optic modules.

5. The fiber optic termination module of claim 1, further comprising an opening in the housing for each fiber optic module for receiving a latch for locking each fiber optic module to the housing.

6. The fiber optic termination module of claim 1, further comprising a plurality of fiber optic modules arranged within the interior of the housing, each of the fiber optic modules being slideably received in one of the longitudinal guides positioned in the interior of the housing.

7. The fiber optic termination module of claim 6, wherein each fiber optic module includes a housing including two spaced-apart major sides extending parallel to one another, the major sides interconnected by two spaced-apart minor sides extending parallel to one another, the major and minor sides extending between front and rear ends of the housing, the front end being open and defined by edges of the two major and minor sides.

8. The fiber optic termination module of claim 7, wherein one of the minor sides defines first arid second round openings, the first opening positioned further from the rear end than the second opening, each of the first and second openings sized to receive a ball end of the spring biased ball plunger.

9. The fiber optic termination module of claim 6, wherein a plurality of spring biased ball plungers are provided on the first side of the housing, each spring biased ball plunger being configured to exert a retention force on one of the fiber optic modules to retain the fiber optic module in a partially removed position with respect to the housing when the fiber optic module is partially removed from the interior of the housing through the open front.

10. The fiber optic termination module of claim 1, wherein the housing also includes cable guides defining passages for receiving cables and routing cables to the open front of the housing.

11. The fiber optic termination module of claim 10, wherein the housing also includes a curved panel at the open front to facilitate cable routing between the cable guides and the open front.

12. The fiber optic termination module of claim 1, wherein the housing defines an aperture configured to cooperate with a securement arrangement on the fiber optic module to secure the fiber optic module within the housing.

13. The fiber optic termination module of claim 12, wherein the securement arrangement includes a latch to secure the fiber optic module within the housing.
