The 250um fiber is positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire locates in the center of core as a metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Aluminum Polyethylene Laminate (APL) moisture battier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.
Our figure 8 fiber optic cable GYXTC8S GYXTC8A GYTC8S GYTC8A GYTC8Y are also available on request. This type cable is specifically applied for self-supporting aerial installation.
High tensile strength of stranded wires meet the requirement of self-supporting and reduce the installation cast
Good mechanical and temperature performance
High strength loose tube that is hydrolysis resistant
Special tube filling compound ensure a critical protection of fiber
The following measures are taken to ensure the cable watertight:
