GYFTA Non Self-supporting Aeral/Duct Optical Cable 12 Core

GYFTA Cable Loose Tube With Non-metal Central Strength Member and Aluminium Tape

GYFTA FRP fiber optic cable is an outdoor communication optical cable of non-metallic strength member of the loose tube jelly-filled structure, with Al-polyethylene laminated sheath.

The loose tubes are made of high modulus plastics (PBT) and filled with a water resistant filling gel. Loose tubes are stranded around the non-metallic central strength member (FRP), cable core is filled with cable filling compound. The Corrugated Aluminum Tape is longitudinally applied over the cable core, and combined with a durable Polyethylene (PE) sheath.


Outdoor Cable GYFTA is with non-metallic central strength member of FRP and PE sheath. Fiber optic cable GYFTA is suitable for duct or aerial installation. Singlemode or multimode of GYFTA cable can be ordered as per the customer request.


Jelly-filled loose tube

Central non-metallic strength member FRP

Jelly-filled cable core

nonmetallic reinforcement (if necessary)

PE outer sheath

Low loss,low chromatic dispersion

Excellent flexible capability and protection capability against bending

Special excess-length control method and cabling mode makes optical cable good mechanical and environmental properties

Filling water-blocking jelly brings entirely cross section double water-blocking capability

All non-metallic structure brings good anti-electromagnetic interference capability

Laying Method

Aerial and duct

Long distance communication, local trunk line, CATV&computer networks system

    Main Characteristics


    The cable are mainly designed for core network,city network,and access network. It’s suitable for duct, specially for the places with high requirement for moisture-proof.

    Product Characteristic:
    1. Small size,light weight,with good bending resistance performance easy to installation.

    2. Reasonable structure design and precise control for over length ensuring excellent characteristics of mechanical tensile strain and environment temperature.

    3. High strength loose tube material with good performance of hydrolysis resistant,special tube filling compound ensure a critical protection of fiber.Full section filled ensures moisture-proof and water blocking.

    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.
