Description of Product:
In the structure of the cable, the multiple Kevlar yarn is used as reinforcement on the outside of the tight jacketd single mode or multimode ooptical fiber and the fire retardant flat sheath is extruded to form an optical cable. The performance of the product is better than teh national standard as teh premium optical fiber is selected with rational number of Kevlar yarn and design tension and made by special equipment with precision mold.

Features of product:
A perfect screw of good linearity and small extrusion rate is chosen for processing tight jacketed optical fiber with adjustment of vacuum of the extrusion machine. It ensures an even OD of tight jacketed iptical fiber adn good stripping.
Both tight jacket of optical fiber and external sheath are perfect fire retardant sheathing material.
Before tight jacketing of optical fiber, the optical fiber has been strictly selected so that both geometric dimension and transmission performance of the optical cable could satisfy customer demand.
