Optical fiber composite low-voltage insulation cable for indoor connection

Abstract

The invention relates to an optical fiber composite low-voltage insulation cable for indoor connection, which can achieve high speed both-way interaction between a power grid and users and comprises a 1-4 core butterfly lead-in optical cable which is compact in structure, small in volume and applicable to use in indoor sites with small bevelling radius. 1 anti-bending optical fiber, 2 anti-bending optical fibers and 4 anti-bending optical fibers are arranged in an optical fiber in the optical cable, and photo-communication signals can be provided for a plurality of users. One 1.5-10 copper conductor is respectively arranged on two sides of the optical cable, and the conductor is insulated through a protective sleeve made of low smoke zero halogen anti-flaming materials. An optical unit and an electrical unit are integrated together to jointly be located in the protective sleeve. The optical fiber composite low-voltage insulation cable is low in cost, convenient to install and capable of simultaneously transmitting optical signals and electrical signals, and has fireproofing and anti-flaming functions.

Description

technical field [0001] This product involves an optical fiber composite low-voltage insulated cable for indoor access, including an outer sheath, a 1-4-core butterfly lead-in optical cable in the center of the outer sheath, and a low-voltage cable placed on each side of the optical cable. Background technique [0002] Currently on the market, optical cables and electric cables are two different products, so they can only be laid twice. In this case, the purchase cost and construction cost of the two layings are relatively large, and a large amount of pipeline resources are occupied at the same time. The "last mile" of the power grid "Resources are the weakest link in the optical fiber information communication network. Power fiber-to-the-home uses OPLC to build an xPON+PFTTH network to realize high-speed two-way interaction between the power grid and users.
