Photoelectric mixed communication cable

Abstract

The present invention provides a photoelectric mixed communication cable which comprises two light channels and two electric channels. Each of the light channels is formed by internal multimode optical fibers, a loose tube which sleeves the outer side of the multimode optical fibers, and fiber paste arranged in the gap between the multimode optical fibers inside the loose tube. Each of the electric channels is formed by a copper wire in the center and an insulation sleeve which coats the copper wire. The four channels are in a central symmetric arrangement. A soft steel wire reinforcement piece is respectively arranged at the center of the four channels and the adjacent part of every two channels. Wires and optical fibers are combined in one cable, a problem of difficult power taking in many places is solved, at the same time through respectively setting a soft steel wire reinforcement piece arranged at the center of the four channels and the adjacent part of every two channels, the strength and smoothness of the optical fiber and the cable can be ensured, thus the cables in a same office building or relatively near areas do not cross, the normal use of other cables is not influenced, and the optical path transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a photoelectric hybrid communication cable. Background technique [0002] Fiber optics are the next generation transmission medium and have some distinct advantages over copper media. Because the optical fiber does not radiate electronic signals to the outside world, the network using the optical fiber medium has greatly improved in terms of security, reliability and network performance. The bandwidth of optical fiber transmission greatly exceeds that of copper cables, and the maximum connection distance supported by optical fiber is more than two kilometers. It is an inevitable choice to build a large-scale network. There are now two different types of fiber, single-mode fiber and multimode fiber. (The so-called "mode" refers to a beam of light entering the fiber at a certain angle). Multimode fiber uses light-emitting diodes (LEDs) as light emitting devices, while s...

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention provides a photoelectric hybrid communication cable, which combines electric wires and optical fibers in one cable to solve the problem of difficulty in obtaining electricity in many places. Each place is equipped with a soft steel wire reinforcement, which can ensure the strength and flatness of the optical fiber and cable, so that the cables in the same office building or in a relatively close area will not cross and will not affect the cable. Normal use, improve optical path transmission efficiency
