Product Detail Specification

Description

Huruntek uni-tube loose tube CST cable 4 core to 24 core optical fibres are all placed in a fiber jelly filled loose tube. Around the central uni-tube, water-blocking material fiber glass yarn and strength member of corrugated steel tape (CST) wrap the loose tube as a strengthened cable core. Outside, an PE or LSZH black sheath is finished around all loose tube and armour materials.

All optical fibre and jacket colour for choose and customize, different CST cable structures from 4 fibre, 12 fibre, 24 fibre, 48 fibre to 96 fibre, 144 fibre and 288 fibre. Cable sheath printing includes length marking and other information.
