Flexible hinge photoelectric composite cable

Abstract

The invention belongs to the technical field of communication optical cables, and relates to a flexible hinge photoelectric composite cable, which is characterized in that an optical fiber communication unit and an electric transmission unit are arranged in parallel, the optical fiber communication unit is arranged on the left side, the electric transmission unit is arranged on the right side, a longitudinal central reinforcer with a rectangular cross section is arranged in the center between the optical fiber communication unit and the electric transmission unit, the left long side of the rectangular cross section of the central reinforcer is adjacent to the optical fiber communication unit, the right long side of the rectangular cross section of the central reinforcer is adjacent to theelectric transmission unit, a filler is stranded with the optical fiber communication unit, the electric transmission unit and the central reinforcer to form a cable core with an elliptical cross section, and an inner sheath layer, a hinge layer, an outer sheath layer and a support hand are sequentially coated outside the cable core from inside to outside to form the flexible hinge photoelectric composite cable. According to the invention, the flexible hinge photoelectric composite cable solves the influence of outdoor severe environment on the transmission performance of the photoelectric composite cable, improves the flexibility, interference resistance, water resistance, compression resistance and tension resistance, is stable in signal transmission, is easy to lay and construct, and issuitable for data transmission in the fields of military affairs, finance and the like.

Description

technical field [0001] The invention belongs to the technical field of communication optical cables, in particular to a flexible hinge photoelectric composite cable. Background technique [0002] The photoelectric composite cable is suitable for use as a transmission line in the communication access network system. It is a new type of access method. It integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. It is often used in Communication remote power supply system and short distance communication system power supply. [0003] However, photoelectric composite cables are often used in harsh outdoor environments, and it is inevitable that the composite cable will be trampled, squeezed, stretched, impacted, and dragged during construction. Cause damage, and then affect the signal transmission capability, which requires the composite cable to have better compressive stre...

Problems solved by technology

[0003] However, photoelectric composite cables are often used in harsh outdoor environments, and it is inevitable that the composite cable will be trampled, squeezed, stretched, impacted, and dragged during construction. Cause damage, and then affect the signal transmission capability, which requires the composite cable to have better compressive strength, tensile strength, and better flexibility

The current conventional photoelectric composite cable cannot meet the above requirements, and a new type of photoelectric composite cable is needed
