Framework type 8-shaped photoelectric composite cable

Abstract

The invention discloses a framework type 8-shaped photoelectric composite cable. According to the framework type 8-shaped photoelectric composite cable, an outer sheath (8) is in a shape of 8, and the 8-shaped outer sheath (8) is composed of two O-shaped structural units. A framework (1), framework grooves (2), an O-shaped structural unit center reinforcing piece (5), a metal belt (6) and an armor layer (7) are arranged in each O-shaped structural unit, wherein the O-shaped structural unit center reinforcing piece (5) is located in the center of the framework (1), a plurality of framework grooves (2) are formed around the framework (1), the framework (1) is wrapped with the metal belt (6), the armor layer (7) and the outer sheath (8) in sequence from inside to outside, and an optical cable (3) and an electric cable (4) are arranged in the framework grooves (2) respectively. The framework type 8-shaped photoelectric composite cable has the advantages that optical cable transmission and electric cable transmission can be achieved on the same cable and can also be separated, mutual influence is avoided, the structure is compact, a small amount of energy is lost during transmission, dispersion of optical fibers is little, and good mechanical property and environmental property are achieved.

Description

technical field [0001] The invention relates to a composite cable, in particular to a skeleton type figure-eight photoelectric composite cable. Background technique [0002] Modern communication networks not only support telephone services, but also include many data services. At the same time, multimedia such as telephone videos and pictures need to be transmitted. Therefore, network transmission lines with larger capacity and wider frequency bands are required. At present, the photoelectric composite cable, a new type of access method, integrates optical fiber and power transmission copper wire, which saves the cost of cables. It is suitable for occasions that need to provide ordinary telephone, cable TV and broadband services at the same time. It has a wide range of applications. And it can reduce the construction difficulty caused by laying optical cables and cables separately. However, there are still some problems in the current photoelectric composite cable. [0003...

AI Technical Summary

Problems solved by technology

[0004] 2. The "8" shape is used to separate the optical cable and the cable for transmission, which can easily separate the cable and the optical cable during use, but the energy loss is large during the transmission process, the dispersion of the optical fiber is high, and the mechanical performance and environmental performance are poor.
