Core connected to the heart and happy to share
The GYTZA53 optical cable is constructed by embedding 250μm optical fibers into a loose tube made of high-modulus material, filled with a water-blocking compound. The core center contains a metallic strength member. For certain fiber counts, an additional polyethylene (PE) layer is extruded over the metallic strength member. The loose tubes (and filler rods, if applicable) are stranded around the central strength member to form a compact and circular cable core, with gaps filled with water-blocking material. A plastic-coated aluminum tape (APL) is longitudinally applied before extruding an inner PE sheath, followed by a double-sided plastic-coated steel tape (PSP) longitudinally applied and a flame-retardant outer sheath extruded to complete the cable.
Excellent mechanical and thermal properties
High hydrolysis resistance and strength of the loose tube material
Specialized filling compound provides critical fiber protection
Outstanding crush resistance and flexibility
Flame-retardant sheath offers excellent fire resistance
Waterproof performance ensured through:
· Single steel wire central strength member
· Special water-blocking compound in loose tubes
· Fully filled cable core
· Plastic-coated aluminum tape (APL) moisture barrier
· Double-sided plastic-coated steel tape (PSP) for enhanced moisture resistance
· Effective water-blocking materials preventing longitudinal water penetration
