GYTA53 Double Sheathed Outdoor Direct Buried Fiber Optic Cable SM or MM A steel wire as metallic strength member in center

GYTA53 Outdoor Direct Buried Fiber Optic Cable, Double Sheathed Cable

The GYTA53 Double Sheathed Outdoor Direct Buried Fiber Optic 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 highfibre 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. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protectit from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath. The GYTA53 Double Sheathed Outdoor Direct Buried Fiber Optic Cable  CharacteristicsAccurate fibre excess length ensures good mechanical and temperature performance

High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fibre

Specially designed compact structure is good at preventing loose tubes from shrinking

Crush resistance and flexibility
