Fibre optic cable, methods of manufacture and use thereof

A fibre optic cable (500, 700, 1420) comprises one or more fibre units (502, 1302). Each fibre unit comprises two or more optical fibres (506, 1306) embedded in a solid resin material (520, 1320) to form a coated fibre bundle and an extruded polymer sheath (524, 1324). The sheath (524, 1324) of each...

Zusammenfassung:A fibre optic cable (500, 700, 1420) comprises one or more fibre units (502, 1302). Each fibre unit comprises two or more optical fibres (506, 1306) embedded in a solid resin material (520, 1320) to form a coated fibre bundle and an extruded polymer sheath (524, 1324). The sheath (524, 1324) of each fibre unit is primarily polybutylene terephthalate (PBT), with a friction reducing additive such as polydimethylsiloxane (PDMS). The additive may be polythene based and/or polyacrylate based. The fibre unit may be applied in a pullback cable (500, 800, 1100), as a cable for pulling or pushing or as a blown fibre cable (502, 1302).
