Description:
Optical fibers are housed in loose tubes that made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a central strength member to form a cable core. The core is protected with water blocking tape ,a layer of inner PE sheath and corrugated steel tape. Then another layer outer PE sheath is extruded.
