Optical Fiber Cable

Aerial.

The fibers,either of single-mode or multimode type,are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water-resistant filling compound.A steel wire sometimes sheathed with polyethylene (PE) for cable with high fiber count,locates in the center of core as a metallic strength member.Tubes (and fillers) are stranded around the strength member into a compact and circular cable core.After PSP is applied around the cable core,this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.This king of cable is specifically applied for self-supporting aerial installation.
