GYTA-1
Optical Fiber Cable APL Armored Stranded Loose
Tube Duct Installation
The bending insensitive optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The loose tubes with smaller size are stranded to form a cable core. The core is armored with laminated aluminum tape. Then a PE outer sheath is extruded. This structure has a smaller size to enhance installation density of fibres in ducts.

1. Loose Tube: thermoplastic material, containing filled with gel.
2. Optical Fiber: 200um B6a2 Fibre
3. Central Strength Member(CSM): phosphate steel wire.
4. Cable Filling Compound.
5. Aluminum Polyethylene Laminate (APL)
6 Outer Sheath: black polyethylene with APL Tapes.
Features and Applications:
Accurate process control ensuring good mechanical and temperature performances
The material of loose tubes with good hydrolysis resistance and relatively high strength
Tube filling compound providing the key protection for fibres
Using small-sized B6a2 fibres with good micro and macro bending performance
Comply with IEC60794-3-11(2007): Optical fibre cables- Part 3-11
Water resistance of optical cable is ensured by the following measures: Special water-blocking compound filled in loose tubes
Laminated aluminum tape armorCable filling compound ensuring longitudinal water resistance
