Down Sized 60-144F Duct Micro Cable (GYTA)

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 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.

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
• 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 armor
• Cable filling compound ensuring longitudinal water resistance
