Fiber Optic Cable,The structure of GYTA53 (outdoor optical cable used for telecommunication with metalliccentral strength, loose and

layer-stranded tube style, aluminum-polyethylenecover, and vertically corrugated steel tape armored)   is covering the inner-fulfilled

waterproof compound loose tube, which is made ofhigh modulus plastic, with the single mode and multi-mode optical fiber. The center

of the cable’s core is steel wire. For some optical cables with certain number of core, this steel wire could be a strand, or covered with

a tight pack of polyethylene (PE). The compact and round shape cable core is a combination of the loose sleeve pipe (gasket for

packing) and center-strengthened core, thegap in the cable core is filled with water retarding compound. (the core number of the

vertical-laid moisture retarding belt out of the cable core is over 96).The PE sheath will appear after being vertically covered with

the plastic-plated aluminum belt, The polyethylene over layer will be made after the double-side plastic-plated aluminum belt is

covered vertically.
