GYFTA53 Armored Outdoor Optic Cable 96 Core

The fibers,250μm‚are positioned in a loose tube made of a high modulus plastic.The tubes are filled with a water−resustant filling compound.A Fiber Reinforced Plastic locates in the center of core as a non–metallic strength member.The tubes‹and fillers› are stranded around the strength member into a compact and circular core.An Aliminum Polyethylene Laminate(APL) is applied around the cable core.Then the cable core is covered with a thin polyethylene (PE) inner sheath.which is filled with jelly to product it from water ingress.After a corrugated steel tape armor is applied,the cable is completed with a PE outer sheath.


Good mechnical and temperature performance

High strength loose tube that is hydrolysis resistant

Special tube filling compound ensure a critical protection of fiber

Crush resistance and flexibility

The following measures are taken to ensure the cable watertight:

Loose tube filling compound

-100% cable core filling

-APL ,oisture barrier

-PSP enhacing moisture−proof

-Water−blocking material

    GYTA53 / GYTS53 Direct Buried Fiber Optic Cable 144 Core


    GYTA53 is the steel tape armored outdoor fiber optic cable used for direct buried. single mode GYTA53 fiber optic cable and multimode GYTA53 fiber optic cables; fiber counts from 2 to 432.


    Up to 432 fiber cores.

    The loose tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube, which keeps the fiber stress-free while the cable is subjected to longitudinal stress.

    Corrugated steel tape armored and double PE sheath providing excellent crush resistance and rodent resistance.

    Metal strength member provides excellent strain performance.
