Down Sized 300F Composite Duct Micro Cable (GYTA (RS))

The bending insensitive optical fibres, Easy Band® Plus-Mini(200 μm), 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 sub-units. The composite structure is formed by stranding sub-units, armoring with laminated aluminum tape and then extruding a PE outer sheath. This structure allows the optical cable to exceed 216 fibres (in 18 units), which enhances installation density of fibres in ducts.
The length of delivery

• Standard length: 2,000m; other lengths are also available. 

Features

• 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

• High fibre density

• Comply with IEC 60794-3-11(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 armor

• Cable filling compound ensuring longitudinal water resistance
