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