Product Profile
The GCYFY Air Blown Fiber Cable 24 72 Cores is laid by air blown microtubules. First, the air blown microtube is laid in the outer protective tube, and then the microcable is laid in the inlet air blown microtube by air blowing. This laying method has a high fiber density, greatly improves the utilization rate of the pipeline, and is easy to expand the pipeline and divide the cable.
Optical fibers are placed into a loose tube made of high modulus hydrolytic resistant material, and the tube is filled with thixotropic water-blocking fiber paste to form the optical fiber loose tube. A number of optical fiber loose tubes arranged according to the color sequence requirements and possible fillers are arranged around the central non-metal strengthening core to form the cable core in the form of SZ twisting. The gap of the cable core is blocked by dry water blocking material. Then a layer of polyethylene sheath is extruded.

Product Features
- The loose tube material of GCYFY Air Blown Fiber Cable 24 72 Cores has good hydrolysis resistance and lateral pressure resistance. The tube is filled with thixotropic water-blocking fiber paste to buffer and protect the optical fiber and realize water blocking in the whole section of the loose tube.
- Precise control of the remaining length of the fiber in the loose tube and the remaining length of the cable core structure ensures that the GCYFY Air Blown Fiber Cable 24 72 Cores meets the tensile and temperature characteristics required by the product standards.
- Black HDPE outer sheath with UV radiation resistance and environmental stress cracking resistance to ensure the service life of the cable.
- The air-blown microcable is made of non-metal reinforcement, small outer diameter, light weight, moderate hardness, and the outer sheath has a very low friction coefficient, thus the air blowing distance is long.
- In the cable line planning, the microtube can be laid at one time, and the air-blown microcable can be laid in batches according to the actual demand, saving the initial investment cost.
- The combination of microtube and microcable has a high fiber density in the pipeline, which greatly improves the utilization rate of pipeline resources.
- The outer protective tube and microtube are laid on the periphery of the microcable to provide good protection for the microcable.
