Abstract

An optical fiber connector housing or facilitating the cross-connection or interconnection of optical fibers is provided having upper and lower plate members spaced apart from one another with the front edge of the lower plate member extending further forward than the front edge of the upper plate member. A connecter panel depends generally vertically downward from the front edge of the upper plate member thereby defining a shelf portion at the forward part of the lower plate member. A door is hingeably connected to the front edge of the lower plate member thereby defining a forward cable area, at least one side aperture, and at least one top aperture forward of the connector panel.

Claims

1. An optical fiber connector housing for providing cross-connection functions for optical fibers terminated with connectors and having a minimum bend radius, said housing comprising:

(a) upper and lower plate members which are generally horizontal and spaced apart from one another;

said plate members being adapted for attachment to a supporting frame and each having front and rear edges;

the front edge of said lower plate member extending further forward than the front edge of said upper plate member;

(b) a connector panel depending generally vertically downward from the front edge of said upper plate member and connected to said lower plate member along an attachment line which is rearwardly disposed with respect to the front edge of said lower plate member, thereby defining a shelf portion and a rear portion of said lower plate member;

said shelf portion of said lower plate member being between the front edge of said lower plate member and said attachment line;

said rear portion of said lower plate member being between the attachment line and the rear edge of said lower plate member;

said connector panel having a front face and a rear face and being adapted for mounting a plurality of optical fiber adaptors therethrough wherein each said optical fiber adaptor has a front side and a rear side and is adapted for receiving and mounting in optical alignment a pair of optical fibers, said fibers being routed from opposite sides of said adaptor and each being terminated with a connector;

(c) a door having top, bottom and side edges;

said door being hingedly connected at the bottom edge to the front edge of said lower plate member and thereby movable between an open position and a closed position;

wherein, when in said closed condition, said door has a generally vertical orientation and is spaced from and parallel with said connector panel thereby defining a forward cable area, at least one side aperture, and at least one top aperture;

said forward cable area being bounded by said door, the front face of said connector panel, and the shelf portion of said lower plate member;

said side aperture being between the side edge of said door and the front face of said connector panel;

said top aperture being between the top edge of said door and the front face of said connector panel;

wherein, when in said open position, said door is not vertically oriented and vertically aligned with said connector panel, thereby allowing unrestricted access to said forward cable area; and

(d) a means for releasably securing said door in said closed position;

whereby, when said door is in the closed position, a plurality of optical fibers each being terminated with a connector and connected to the front side of an adaptor on said connector panel can be advantageously routed out of said forward cable area by routing a first portion of said plurality of fibers through at least one side aperture and routing a second portion of said plurality of fibers through at least one top aperture, thereby reducing the density of the cables routed in each direction while said door protects said connectors and optical fibers in said forward cable area from damage and maintains the minimum required bend radius of the optical fibers.

2. The optical fiber connector housing of claim 1, wherein said door is selectively removable from said housing.

3. The optical fiber connector housing of claim 2, wherein said door comprises a transparent material allowing visual inspection of the optical fiber cables, connectors, and adaptors in said forward cable area when said door is in the closed position.

4. The optical fiber connector housing of claim 3, wherein said transparent material of said door significantly attenuates the transmission of light radiation at selected wavelengths.

5. The optical fiber connector housing of claim 3, wherein said transparent material is a plastic.

6. The optical fiber connector housing of claim 3, wherein said transparent material is a glass.

7. The optical fiber connector housing of claim 1, wherein said means for securing said door comprises a bracket extending from said connector panel and releasably interfitting with a latch mechanism mounted on said door.

8. The optical fiber connector housing of claim 1, further comprising cable management brackets mounted on said shelf portion of said lower plate member for releasably securing fiber optic cables routed from said adaptors through said side aperture.

9. The optical fiber connector housing of claim 1, further comprising side plate members connected between said upper plate member and said rear portion of said lower plate member thereby defining a rear cable area bounded by said upper plate, said rear portion of said lower plate, said side plates, and said rear face of said connector plate.

10. The optical fiber connector housing of claim 9, further comprising a rear plate member connected to a rear portion of said housing to enclose said rear cable area.

11. An optical fiber connector housing for providing cross-connection functions for optical fibers terminated with connectors and having a minimum bend radius, said housing comprising:

(a) first and second plate members which are generally parallel and spaced apart from one another;

said plate members being adapted for attachment to a supporting frame and each having front and rear edges;

the front edge of said second plate member extending further forward than the front edge of said first plate member;

(b) a connector panel connected to the front edge of said first plate member and connected to said second plate member along an attachment line which is rearwardly disposed with respect to the front edge of said second plate member, thereby defining a shelf portion and a rear portion of said second plate member;

said shelf portion of said second plate member being between the front edge of said second plate member and said attachment line;

said rear portion of said second plate member being between the attachment line and the rear edge of said second plate member;

said connector panel having a front face and a rear face and being adapted for mounting a plurality of optical fiber adaptors therethrough wherein each said optical fiber adapter has a front side and a rear side and is adapted for receiving and mounting in optical alignment a pair of optical fibers, said fibers being routed from opposite sides of said adapter and each being terminated with a connector;

(c) a generally rectangular door having two main edges oriented generally parallel to the front edge of said second plate member and two side edges connected between said main edges;

said door being releasably connectable to at least one of said plate member and said connector panel, and thereby being movable between an open position and a closed position;

wherein, when in said closed condition, said door is positioned with a first of said main edges adjacent the front edge of said second plate member, and said door is oriented parallel to and aligned with said connector panel, thereby defining a forward cable area, at least one side aperture, and at least one main aperture;

said forward cable area being bounded by said door, the front face of said connector panel, and the shelf portion of said second plate member;

said side aperture being between the said edge of said door and the front face of said connector panel;

said main aperture being between a second of said main edges of said door and the front face of said connector panel;

wherein, when in said open position, said door is not oriented parallel to and aligned with said connector panel, thereby allowing unrestricted access to said forward cable area; and

(d) a means for releasably connecting said door to at least one of said plate members and said connector panel;

whereby, when said door is in the closed position, a plurality of optical fibers each being terminated with a connector and connected to the front side of an adaptor on said connector panel can be advantageously routed out of said forward cable area by routing a first portion of said plurality of fibers through at least one side aperture and routing a second portion of said plurality of fiber through at least one main aperture, thereby reducing the density of the cables routed in each direction while said door protects said connectors and optical fibers in said forward cable area from damage and maintains the minimum required bend radius of the optical fibers.
