There are two types of air-blown microfiber cables: central-tube type (GCYFXTY) and stranded-loose-tube type (GCYFY).
(1) The central-tube type (GCYFXTY) has a structure where a 250um fiber is placed in the center of a loose tube made of high-modulus material filled with non-toxic waterproof compound (gel), and then covered with a PE jacket. Its characteristics and advantages are:
The gel-filled loose tube provides critical protection for the fiber.
High fiber density: 2-24 cores.
Small diameter (2-4 cores, 2.0mm), light weight, and easy to upgrade. (See structure 1)
Suitable for 5/3.5mm microducts. (See structure 1)
The groove-featured jacket structure enhances air-blowing performance. (See structure 1)
(2) The stranded-loose-tube type (GCYFY) has a structure where a 250um fiber is placed in a loose tube made of high-modulus material filled with gel, and the tube is twisted around a non-metallic central strength member (FRP) and surrounded by dry water-blocking material to form the cable core. A thin PE jacket is extruded over the cable core. Its characteristics and advantages are:
The gel-filled loose tube provides critical protection for the fiber.
Dry water-blocking cable core (no gel) for low-carbon and environmental protection.
High fiber density: 2-288 cores.
Small diameter (288 cores, 9.4mm), light weight, and easy to upgrade.
Innovative jacket structure enhances air-blowing performance.
Optional 200μm fiber available (144 cores, 6.0mm, standard size 7.9mm).
