Fire Resistant Central Loose Tube Fiber Optic Cables

Application:

These cables are characterized by light weight and small diameter, suitable for both aerial and duct installation.

They are mainly installed inside buildings, tunnels,subways or closed areas in general, specially designed to

guarantee the signal transmission even in case of fire. The cable can also be used for direct burial for armoured

version.

Standards:

Basic design to Telcordia GR-20 / RUS 7 CFR 1755.900 (REA PE-90) / ICEA S 87-640

Cable Construction:

Fibers: Single mode fibers, with loose tube technology.

Structure: Central loose tube cable contains one tube with 12 core single mode fibers, which are filled with

water blocking gel.

Fire barrier: The jelly filled tube is wrapped with a fire barrier mica glass tapes.

Water blocking: The jelly filled tube is waterblocked by using swellable tape and thread.

Reinforcement: Fiber glass is wound around the tube to provide physical protection and tensile strength, with

added fire protection.

Armouring(optional): Corrugated steel tape armour is applied over cable core.

The 0.15mm thick steel tape is coated with a copolymer and applied with an overlap.

Outer Sheath: Thermoplastic LSZH compound type LTS3 as per BS 7655-6.1
