Abstract
Abstract In a submarine repeater for a fibre optical transmission system, the cable and tail fibres at the A and B ends of the repeater are accommodated in storage structures. Each structure comprises two bodies 12, 13 (FIG. 1) having circular surface grooves or channels 125, 135 in which respective cable or tail fibres are stored. Straight channels 126, 136 provide communication between the circular channels and accommodate splices between the fibres stored therein.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
An optical fibre storage arrangement for a telecommunications repeater whereby to provide an interface between a telecommunications cable and regeneration means, the storage arrangement including a first generally cylindrical body having a plurality of first circular surface grooves one for each fibre of said cable and within which a plurality of turns of that fibre are accommodated, a second generally cylindrical body having a plurality of second circular surface grooves one for each said first groove and each accommodating a plurality of turns of a respective tail fibre associated with the regeneration means, further surface grooves in said first and second bodies each providing communication between respective first and second circular grooves and accommodating a splice between the fibres stored in those grooves, and casing means for retaining the fibres and splices within the grooves.
Claim 2
Dependent Claim
135 words
An optical fibre storage arrangement for a telecommunications repeater whereby to provide an interface between a telecommunications cable and regeneration means, the storage arrangement including a first generally cylindrical body having a plurality of first circular surface grooves one for each fibre of said cable and within which a plurality of turns of that fibre are accommodated, a second generally cylindrical body having a plurality of second circular surface grooves one for each said first groove and each accommodating a plurality of turns of a respective tail fibre associated with the regeneration means, further surface grooves in said first and second bodies each providing communication between respective first and second circular grooves and accommodating a splice between the fibres stored in those grooves, and casing means for retaining the fibres and splices within the grooves.
Claim 3
Dependent Claim
43 words
An optical fibre storage arrangement as claimed in claim 1, wherein said casing means comprises a mating pair of semi-cylindrical shells disposed in abutment with the surface of the first and second cylindrical bodies whereby to retain the fibres stored in the grooves.
Claim 4
Dependent Claim
22 words
An optical fibre storage arrangement as claimed in claim 2, wherein said first and second bodies are formed from a plastics material.
Claim 5
Dependent Claim
37 words
An optical fibre storage arrangement as claimed in claim 3, wherein said first cylindrical body is mounted on a bulkhead coupling having an axial bore via which fibres are led from a cable to the first body.
Claim 6
Dependent Claim
138 words
A submarine telecommunications repeater provided with an optical fibre storage arrangement for a telecommunications repeater whereby to provide an interface between a telecommunications cable and regeneration means, the storage arrangement including a first cylindrical body having a plurality of first circular grooves one for each fibre of said cable and within which a plurality of turns of that fibre are accommodated, a second cylindrical body having a plurality of second circular surface grooves one for each said first groove and each accommodating a plurality of turns of a respective tail fibre associated with the regeneration means, further surface grooves in said first and second bodies each providing communication between respective first and second circular grooves and accommodating a splice between the fibres stored in those grooves, and casing means for retaining the fibres and splices within the grooves.
Claim 7
Dependent Claim
138 words
A submarine telecommunications repeater provided with an optical fibre storage arrangement for a telecommunications repeater whereby to provide an interface between a telecommunications cable and regeneration means, the storage arrangement including a first cylindrical body having a plurality of first circular grooves one for each fibre of said cable and within which a plurality of turns of that fibre are accommodated, a second cylindrical body having a plurality of second circular surface grooves one for each said first groove and each accommodating a plurality of turns of a respective tail fibre associated with the regeneration means, further surface grooves in said first and second bodies each providing communication between respective first and second circular grooves and accommodating a splice between the fibres stored in those grooves, and casing means for retaining the fibres and splices within the grooves.
