Submarine Optical Fiber Cable GYTA33
GYTA33 is a double armored loose tube fiber optic cable designed for direct burial and underwater installation. Full cross-section water-blocking structure ensures excellent moisture resistance. Loose tubes filled with special jelly protect fibers from stress. Phosphate steel central strength member offers high modulus and corrosion resistance. Double-layer corrugated aluminum tape with steel wire armor provides superior tensile, crush, and impact performance, suitable for harsh submarine and underground environments.
