Stranded Loose Tube Micro-duct Air-blown Cable(GCYFY)

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member andsurrounded with dry water-blocking material to form a cable core. An extremely thin outer PE sheath is extruded outside the core.

Characteristics

Small diameter and light weight
Non-metallic structure
Semi-dry core design, easy for splicing
Suitable for long distance air blowing installation
Blowing distance up to 1000m
