Underground Directly Buried Central Outdoor Loose Tube cable GYXTW53

The fibers are placed in a losse tube made of PBT.  The tube is filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally.  Between the PSP and the loose tube water -blocking material is applied to keep the cable compact and waterlight.  Two parallel steel wires are placed at the two sides of the steel tape,over which a thin PE inner sheath is applied.  After the PSP is longitudinally applied over the inner sheath,the outdoor armored fiber optic cable is completed with a PE outer sheath

FEATURES:

Low attenuation and dispersion, special control of exceed length ensure the good transmission performance in varying environment.

Excellent mechanical performance

Good flexibility and bending performance

Small outer diameter, lightness and compact construction

APPLICATION:

Long-distance teecom,LAN in high -votage area or access to telecom network

Installation: Sef-support aeria

Stranded loose tube non-metallic strength member and non-armored cable (GYFTY) construction is that 250um fibers are positioned in a loose tube which is made of high modulus plastic and filled with a water-resistant filling compound; A fiber reinforced plastic (FRP), sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a non-metallic strength member; Tubes are stranded around the strength member into a compact and circular cable core; After the cable core is filled with the filling compound which protects it from water ingress, the cable is completed with a polyethylene (PE) sheath.

Main Features

Good mechanical and temperature performance

High hydrolysis resistance and high strength loose tube

Good crush resistance and flexibility

High tensile strength ensured by FRP central strength member

Good anti-electromagnetism due to non-metallic central strength member (FRP)

Standards

GYFTY cable complies with Standard IEC 60793, IEC60794, TIA/EIA, ITU-T

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.

Features

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.

Outdoor GYTA53 Fiber Optic Cable with Corrugated Steel Armoured Tape

Application: Duct and Aerial, Direct Buried

Jacket: PE material

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.

Characteristics

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
