Problems solved by technology

[0003] The existing metal armor modes such as stainless steel strips and galvanized steel wires are undoubtedly the most effective anti-rodent methods, but their cost is relatively high. Based on cable safety considerations, they can be used in small quantities on some special lines, but they will not be widely promoted.

Abstract

The invention discloses a light type anti-chewing and anti-thunder optical fiber and cable with easy stripping, comprising a loose tube disposed in the center, and a plurality of glass fibers disposed in the loose tube. Two non-metal reinforced rods are disposed at the left and right side of the loose tube in parallel, and are at the same plane. The loose tube and the outer surfaces of the two non-metal reinforced rods are coated by a flat type outer sheath. The upper surface and the lower surface of the loose tube are respectively coated with thermosetting glass fiber yarn.

Description

technical field [0001] The invention relates to an optical fiber cable, in particular to a light-weight anti-biting anti-lightning and easy-to-stripping optical fiber cable. Background technique [0002] As the line medium of optical network construction, optical cable is an indispensable part of the optical access network (OAN) network. It realizes the link between the optical line terminal (OLT) and the optical network unit (ONU), and completes the service The conversion of the relevant signaling protocol between the node interface (SNI) and the user network interface (UNI). As the last mile of FTTx, the access network is directly connected to the terminal equipment through the OLT. The wiring is dense and the single information capacity requirement is small. Therefore, the optical cable used in the access network segment is required to have the characteristics of simple structure, stable performance and convenient construction. . [0003] The existing metal armor modes ...
