Central Tube Light-Armored Optical Cable

Product Overview

Central tube light-armored optical cable (e.g. GYXTW) uses a hydrolysis-resistant high-strength loose tube filled with special jelly to protect the fibers, with good mechanical and temperature performance. Double-coated steel tape improves moisture barrier; two parallel steel wires ensure tensile strength while retaining crush resistance and flexibility. Small diameter, light weight, and easy installation suit duct and light-armored applications. Stable and reliable for telecom network build-out and O&M.

Construction:
Central tube loose-tube structure
Armor:
Double-coated steel tape (PSP)
Strength Design:
Two parallel steel wires
Features:
Small diameter, light weight, easy to install
