The GYTY53 Outdoor Direct Buried Fiber Optics Cable, either of single-mode or multimode type, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire sometimes sheathed with polyethylene (PE) for cable with high fibre count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. After the PSP Is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
Characteristics
Accurate fibre excess length ensures good mechanical and temperature perfonnanceHigh strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fibreSpecially designed compact structure is good at preventing loose tubes from shrinkingCrush resistance and flexibilityhe following measures are taken to ensure the cable watertight:Steel wire used as the central strength memberLoose tube filling compound100% cable core fillingPSP enhancing moisture-proofWater-blocking materialGYTY53 Outdoor Direct Buried Fiber Optics Cable
