Reduced diameter indoor fiber optic cable

摘要

Tight buffered optical fiber cables for indoor use as jumper or interconnect cables have a reduced outer diameter and nonetheless pass many recognized mechanical and environmental test procedures. A single optical fiber cable has an outer diameter of equal to or less than 1500 mu m, and a dual optical fiber cable has an outer diameter of equal to or less than 2000 mu m. A layer of loose tensile strength yarn is disposed between the tight buffered optical fiber or optical fibers and the outer jacket. The cables may be made of flame retardant materials for riser or plenum applications.
