outdoor optical cables used for telecommunication with metallic central strength, the steel-PE central tube complete all-filled
The structure of GYXTW (outdoor optical cables used for telecommunication with metallic central strength, the steel-PE central tube complete all-filled with steel wire) is covering the inner-fulfilled waterproof compound loose tube, which is made of high modulus plastic, with the single-mode optical fiber. The waterproof belt and steel belt covered vertically out of the loose tube, two parallel steel wire on the both sides of the cable core are be used as the strengthen part and become the optical cable.
It controls the extra length of the optical fiber precisely to ensure the good performance of stretch-proof and temperature characteristic of the optical cable.
The PBT loose tube material has good performance of hydrolyze-proof,the special balm is filled with the tube to protect the optical fiber.
The smooth outer sheath provides a smaller friction coefficient in the installation of the optical cable.
The PE sheath has excellent performance of radiation-proof of sun
We take the steps as follow to ensure the waterproofness of the optical cable:
The special water-proof compound filled in the loose tube.
Complete filled with the core of the optical cable
Plastic-plated steel belt moisture barrier
With the development of the demand of telecommunication, the requirement of optical cable in some kinds of industries like multimedia,internet and videoconference which need high transmission speed makes optical cable become the basic media of transmission. We use the normal and nonzero dispersion single mode optical fiber for the optical cables to run the transmission mode like SDH/SONET, ATM and the transmission system like WDM, DWDM efficiently. The excellent design of the twist-layer structure for the loose tube and the material with good quality provide the overall protection of our optical fiber to resistant the terrible whether and environment. The products are especially suitable for the urban backbone transmission network and the accessing network of the users.
