An assembly for use in connecting optical fibers includes a housing ( ) for optical fiber joints and a fiber routing device ( ) associated with the housing. The housing has a first inlet ( ) for receiving optical fibers from a primary side of an optical fiber network and a second inlet ( ) for receiving optical fibers from a customer side of an optical fiber network. The fiber routing device ( ) has an outlet ( ) for feeding fibers from the customer side of the optical fiber network into the second inlet ( ) and two inlets ( ) for receiving the customer-side optical fibers for feeding to its outlet.

Connecting optical fibers

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.

Assembly for use in connecting optical fibers

An installation 10 comprising a line 12 extending between and suspended from a plurality of spaced apart aerial suspension locations 14 defines a passage for an optical fiber unit. The line comprises a plurality of elongate tensile resistant tubes 18 connected end-to-end by respective connectors 20. The line is secured to each suspension location by respective securing means 22 which are secured to said line at two spaced apart locations 28, 30 thereon such that the portion 26 of said line between these locations is untensioned and includes a connector 20. The securing means 22 is adapted to allow tensioning of the portion 26 of said line when the tensile load on the line adjacent thereto on either side of said suspension location reaches a first predetermined amount, and the connector 20 is adapted to cause the end-to-end connection of the tensile resistant tubes 18 connected thereby to break when the tensile load on said portion reaches a second predetermined amount. The first and second predetermined amounts are less than the tensile load for breaking the tensile resistant tubes and said second amount is no greater than said first amount.
