Novel optical cable for communication between underwater equipment and equipment in cabin body

Abstract

The invention provides a novel optical cable for communication between underwater equipment and equipment in a cabin body, which is light in weight, easy to bend, good in water resistance, wear resistance, oil resistance, low-temperature flexibility and flame retardance, and capable of realizing rapid wiring and repeated folding and unfolding use. A central reinforcing member, a loose tube, a wrapping tape, an inner sheath, an aramid fiber braid layer and an outer sheath are sequentially arranged at the radial center of the cable from inside to outside. The central reinforcing member is an aramid fiber extrusion molding flame-retardant sheath. Optical fibers are distributed in an inner cavity of the loose tube. Internal spaces of the optical fiber and the loose tube are filled with fiber paste. The loose tube is twisted around the central reinforcing member to form an equivalent circular cable core, the wrapping tape wraps an equivalent outer ring of the cable core, the inner sheath wraps an outer ring of the wrapping tape, the aramid fiber braid layer is annularly distributed on the outer ring of the inner sheath, and the outer sheath wraps the outer ring of the aramid fiber braidlayer.

Description

technical field [0001] The invention relates to the technical field of optical cable structure, in particular to an optical cable for communication between novel underwater equipment and cabin internal equipment. Background technique [0002] In the existing structure of the optical cable used for communication between underwater equipment and equipment inside the cabin, the optical fiber is located in a loose tube with fiber paste; the center of the cable core is a steel wire (PE cushion may be added), and the steel wire is surrounded by a loose tube, The filling rope is twisted, and the gap inside and outside the cable core is filled with cable paste; the outside of the cable core is sheathed with steel or aluminum tape. After being armored by one or more single thin round steel wires, the polyethylene outer sheath is finally extruded into cables. Because the optical cable is armored with steel wire, the central strength member is made of steel wire material, which is hea...

AI Technical Summary

Problems solved by technology

Because the optical cable is armored with steel wire, the central strength member is made of steel wire material, which is heavy and has high bending rigidity; and the traditional optical cable central strength member pad, inner sheath and outer sheath are made of polyethylene material, which is not very wear-resistant , oil resistance, low temperature flexibility, flame retardant effect
