Optical fiber patch panel
| Details |

Primary Examiner: Healy; Brian

Attorney, Agent or Firm: Nixon & Vanderhye
A patching panel (4) for housing multiple connections in an optical communication system. The panel is corrugated to define alternately disposed angled faces and apertures are provided on alternate faces (6) on each side of a central line parallel to the corrugations so that the ends of terminal connectors mounted in the patch panel are angled away from the center of the panel in a direction towards the nearest side of the panel. Preferably the angle progressively decreases towards the side. A flange extends from a frame supporting the patch panel on each side to prevent direct line of sight into a supported connector. |

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Referring firstly to FIG.
2, a preferred patch panel assembly is shown which comprises a substantially rectangular section frame having a back wall 1, side walls 2 and front wall portions 3.
The central part of the front of the frame between wall portions 3 is open to give access to a patch panel 4.
The front of the frame may be open by virtue of a large central aperture leaving upper and lower front wall portions for support in addition to the side portions 3, or the entire central part of the front may be open from top to bottom between the wall portions 3.
Adjacent to each side wall 2 there are fibre support trays 5 or fingers for separating and guiding the lines from individual connectors on the patch panel.
It will be seen from FIG.
2 that the patch panel 4 is not a planar sheet as in the prior art, but has a zig zag corrugated section.
Apertures for individual connectors are provided on alternate faces of the corrugations, as shown in FIG.
1.
The faces with apertures, referenced 6, are those faces that, viewed from the front, are facing towards the nearest front corner of the frame (or more generally they are angled away from the centre towards the nearest side that runs parallel to the faces of the corrugations) giving rise to a change of direction at the centre.
Fibre terminations, such as from a trunk line, are threaded through access ports in the side walls 2 and are supported on the fibre support fingers 5, as shown for fibre 7.
This fibre termination is then coiled in a loop 8 and the terminal connector inserted into an aperture in the patch panel from the rear.
In a similar manner a subscriber line, for example, is connected as shown for a fibre referenced 10, the line again entering through a port in the side wall, being supported by fibre support fingers, coiling in loop 11 and then being connected to a connector of an appropriate line in the patch panel.
The fibre support fingers are generally arranged in layers, each layer serving several horizontal layers of the patch panel
