Central Tube Flame-Retardant Optical Cable

Product Overview

Central tube flame-retardant optical cable (e.g. GYXTZW) uses a high-strength hydrolysis-resistant loose tube filled with special jelly to protect the fibers, plus double-coated steel tape (PSP) for moisture barrier performance and two parallel steel wires for tensile strength. Special flame-retardant jacket materials deliver excellent fire performance while balancing crush resistance and flexibility. Small diameter and light weight ease installation and support longer delivery lengths. Stable and reliable for telecom network build-out and O&M.

Construction:
Central tube loose-tube structure
Flame Retardance:
Special flame-retardant jacket material
