GYTA333 (Double-layer Steel Wire Armored, Corrugated Aluminum Tape Armored, Stranded Loose Tube Cable)

Underwater Optical Fiber Cable

The loose tubes are made of high modulus plastics (PBT) and filled with water resistant filling gel. Loose tubes are stranded around the metallic central strength member, cable core is filled with cable filling compound. The corrugated aluminum tape is longitudinally applied over the cable core, and combined with polyethylene (PE) inner sheath. Double layer galvanized steel wires are stranded around inner sheath, and then extruded with PE outer sheath.
