Abstract

The present invention provides an assembly for use in connecting optical fibers. The assembly may comprise a plurality of housings for housing connections between optical fibers and a guide arrangement for guiding optical fibres into the housings. The guide arrangement may comprise a plurality of guide devices each having one inlet port for the passage of optical fibres into the guide arrangement and one outlet port for guiding optical fibers into the housing. The guide arrangement may also include one further inlet port for receiving optical fibres from another guide device and one further outlet port for guiding optical fibres to another guide device.

Claims

1. An assembly for use in connecting optical fibres, the assembly comprising a plurality of housings for housing connections between optical fibres and a guide arrangement for guiding optical fibres into said housings, said guide arrangement comprising a plurality of guide devices mounted side-by-side, each guide device having at least one inlet port for the passage of optical fibres into the guide arrangement, a plurality of outlet ports associated with respective said housings for guiding optical fibres into the associated housing, a plurality of further inlet ports for receiving optical fibres from another one of said guide devices when positioned adjacent said guide device on one side thereof and a plurality of further outlet ports for guiding optical fibres to respective said further inlet ports of another one of said guide devices when positioned adjacent said guide device on another side thereof, said guide arrangement comprising at least two guide devices.

2. An assembly as claimed in claim 1, wherein the or each inlet port has a substantially cylindrical portion to correspond with the shape of a tubular member containing optical fibres so that a push-fit connection can be achieved by such a tubular member in the inlet port.

3. An assembly as claimed in claim 1, wherein each guide device provides a plurality of fixed tracks extending from said at least one inlet port to respective said outlet ports and to respective said further outlet ports for guiding optical fibres from the or each inlet port to respective said outlet ports and to respective said further outlet ports.

4. An assembly as claimed in claim 1, wherein each guide device provides a plurality of fixed tracks extending from said further inlet ports to respective said outlet ports and to respective said further outlet ports for guiding optical fibres from the further inlet ports to respective said outlet ports and to respective said further outlet ports.

5. An assembly as claimed in claim 3, wherein said fixed tracks are channels and have a bend radius not less than a predetermined distance for reducing signal attenuation in optical fibres disposed therein.

6. An assembly as claimed in claim 1, wherein the further outlet ports of one of said guide devices are adjacent the further inlet ports of another of said guide devices to assist in guidance of optical fibres between said further outlet parts of said one guide device and the further inlet ports of said another guide devices.

7. An assembly as claimed in claim 1, wherein fixed tracks provide tracks which extend from the or each inlet port of one of said devices to the outlet ports of another of said guide devices and said tracks have a bend radius not less than a predetermined distance for reducing signal attenuation in optical fibres disposed in the tracks.

8. An assembly as claimed in claim 5, wherein said fixed tracks have a bend radius of not less than 30 mm.

9. An assembly as claimed in claim 7, wherein said tracks have a bend radius of not less than 30 mm.
