Reinforced type light optical fiber and cable with rat-proof function

Abstract

The invention discloses a reinforced type light optical fiber and cable with rat-proof function, 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 a thermosetting glass fiber yarn tape. The flat type outer sheath is respectively provided with two inclined-V-shaped tearing grooves at the upper part and lower part of the loose tube, and the inclined-V-shaped tearing groove directs towards the area between the loose tube and the non-metal reinforced rod. The inner part of the flat type outer sheath is respectively provided with the thermosetting glass fiber yarn tape at the upper part and the lower part of the loose tube. The thermosetting glass fiber yarn tape is composed of a plurality of glass fiber rods in parallel arrangement. The reinforced type light optical fiber and cable with rat-proof function is advantageous in that when the glass fiber protective layer is bitten by rodents, the oral cavity of the rodent will be damaged by the glass fiber protective layer, and the rodent will stop biting the optical cable, and thereby the optical fiber can be protected from being bitten, and usage security is quite high.

Description

technical field [0001] The invention relates to an optical fiber cable, in particular to a reinforced light optical fiber cable with a mouse-proof function. 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. .

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.
