Optical Distribution Indoor Cable

Product Description

Tight-Buffered Distribution Indoor Cable

 

Tight-buffered fiber distribution cable consists of several tight-buffered fibers consolidated in a single cable. Compared with the bare fiber, the tight-buffered fiber is coded with an additional 900um layer over the 250um fibers for protection. Generally, the tight-buffered distribution cable comes in various fiber counts ranging from 2 to 144 fibers. According to different application requirements, these cables are usually plenum or riser rated but can also be constructed as an indoor/outdoor or low-smoke (LSZH) cable.

Features

  • Contains several tight-buffered fibers bundled under the same jacket with Kevlar strength members
  • Lightweight and softness.
  • Excellent stripping performance of tight buffer fiber.
  • Cable diameter and bending radius are small.
  • It can be installed freely in a narrow room.
