GYXTW Central Loose Tube Fiber Optic Cable

GYXTW fiber optic cable is a central loose tube outdoor cable designed for reliable fiber optic communication networks. It features optical fibers housed in a PBT central loose tube, surrounded by water-blocking materials and protected by plastic-coated steel tape (PSP) armor. Two parallel steel wires provide tensile reinforcement, while a black MDPE outer sheath offers protection against outdoor environmental conditions.

The steel tape armored construction provides enhanced mechanical protection and moisture resistance, making GYXTW suitable for underground duct installation and outdoor telecommunications networks. Available in 2–24 fiber configurations, the cable supports a range of outdoor fiber connectivity requirements.

GYXTW fiber optic cable features a central loose tube construction with PSP steel tape armor, parallel steel wire reinforcement, and a protective MDPE outer sheath.

Optical Fibers
G.652.D single-mode optical fibers provide reliable optical signal transmission.

Tube Filling Compound
Fills the central loose tube to protect the optical fibers against moisture.

PBT Central Loose Tube
Houses and protects the optical fibers, helping reduce mechanical stress during installation and operation.

Parallel Steel Wires
Two parallel steel wires provide tensile reinforcement and improve mechanical stability.

Water-Blocking Compound
Helps prevent longitudinal water penetration and protects the cable core against moisture.

PSP Steel Tape Armor
Plastic-coated steel tape provides additional mechanical protection and improves crush resistance.

MDPE Outer Sheath
The black medium-density polyethylene outer sheath protects the cable against moisture, abrasion, and outdoor environmental conditions.

Compact Central Loose Tube Design
The PBT central loose tube provides a compact structure and reliable protection for optical fibers.

Enhanced Mechanical Protection
PSP steel tape armor provides additional protection against crushing and external mechanical stress.

Reliable Tensile Reinforcement
Two parallel steel wires enhance tensile strength and provide mechanical stability during installation.

Effective Water-Blocking Design
Tube filling and water-blocking compounds help prevent moisture penetration and protect the optical fibers.

Durable MDPE Outer Sheath
The black MDPE outer jacket provides protection against moisture, abrasion, and outdoor environmental conditions.

Designed for Underground Duct Installation
The armored construction is suitable for underground duct networks and outdoor telecommunications infrastructure.
