Described are cable designs adapted for aerial installations wherein the cable comprises a bundle of multifiber tight buffer encasement units, with a conformal thin skin containment layer surrounding the bundle. The multifiber tight buffer encasement units have an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The thin skin containment layer provides cable integrity with a minimum of added size and weight. The thin skin containment layer encasement is encased in an outer protective jacket.

Aerial optical fiber cables

Described are new cable designs for indoor installations wherein the cable comprises a dual-layer optical fiber buffer encasement of acrylate resin. The buffer encasement has an acrylate compliant inner layer that protects the fiber and minimizes stress transfer to the fiber; and a hard, tough acrylate outer layer that provides crush resistance. The dual-layer optical fiber buffer encasement is wrapped with reinforcing yarn and encased in an outer protective jacket. A dual jacket embodiment adapted for indoor/outdoor installations is also described.

An assembly for use in connecting optical fibers comprising a plurality of housings for housing optical fibre connections. Each housing is pivotally mounted with respect to an associated rigid routing member which has passages for routing fibers to the housing via respective flexible conduit means which extend between the routing member and the housing. Adjacent routing members are push-fittable together such that the housings are in an aligned bank when in stowed positions. Each housing is pivotable from its stowed position out of alignment with the other housings for access.

Connecting optical fibres

Assembly for use in connecting optical fibers having pivotally mounted

A system for guiding optical fibres comprises a device which includes a plurality of units, each of which defines a row of ducts extending from a first end of the unit to a second end thereof for guiding optical fibres. The units are arranged successively in overlapping relationship with their first ends in substantial alignment at an end portion of the device and their second ends being spaced apart at successively increasing distances from the device end portion.

Guiding optical fibres

Apparatus for use in interconnecting optical fibers comprises a shelf 12 slidably mounted between a retracted position (FIG. 2) and an extended position. Housings 48 for locating fiber interconnections are mounted on the shelf 12. A plurality of tubes 22 are connected to respective further tubes 26, which are connected to the housings 48, by tube connector 30. The tubes 22 and 26 guide optical fibers to the housings 48. Each tube 22 has a substantially helical configuration over a portion 24 of its extent located behind the shelf 12 to accommodate sliding movement of the shelf.
