Tight Buffer Fiber(GJFJV)

 1-1-紧套光纤.png


Description

Tight Buffer Fiber is produced as that fiber is sheathed by buffer material. The selection of top-quality fiber, the specific production equipment and the accurately designed die make the performance of product.

  

Characteristics

Good uniformity of the outer diameter of tight buffer fiber and excellent strippability

Good performance of flame-retardant

Low induced attenuation within the operating temperature range

Excellent geometrical dimension of the fiber

  

Applications

Indoor cable

Making jumper, pigtail

Data communication
