GYTA fiber optic cable is a stranded loose tube outdoor cable widely used for overhead, duct, and even direct burial applications. It combines strong mechanical performance with superior water resistance.
Fiber Type: GYTA
Application: Overhead laying, Duct, Direct Burial
Fiber Count: 1–144 fibers
Recommended Index: ⭐⭐⭐⭐⭐ (5 stars)
Multiple loose tubes stranded around a central strength member (steel wire).
Full cable core filling with water-blocking gel for complete moisture protection.
Steel-Polyethylene Bonded Sheath (PSP): Offers excellent moisture and crush resistance.
Outer layer is a polyethylene (PE) sheath, protecting the cable from environmental stress including UV radiation.
Optical fibers (250μm) are housed in high-modulus plastic loose tubes.
The loose tubes are filled with water-resistant filling compound.
A steel wire (sometimes PE-sheathed for high fiber counts) is used as the central strength member.
Tubes and fillers are stranded around the central member to form a compact and circular cable core.
The entire core is longitudinally wrapped with PSP and filled to protect against water ingress.
Finished with a tough polyethylene (PE) sheath for added protection.
Excellent mechanical performance and temperature stability.
High-strength, hydrolysis-resistant loose tubes.
Special filling compound offers critical fiber protection.
Compact structure design prevents tube shrinkage.
High crush resistance and good flexibility.
PE sheath protects against ultraviolet (UV) radiation.
Full waterproof structure using:
Central steel wire strength member
Tube filling compound
100% cable core filling
PSP moisture-proof barrier
Overhead installation
Duct installation
Direct burial installation
