Description:
Optical fibers are housed in loose tubes that are made of high-modulus plastic and filled with jelly. The steel wires around the central loose tube to form a cable core. The core is covered by PE sheath. Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer sheath is extruded.
