What is the GYXTW fiber optic cable?

Central tube Steel polyethylene laminate Armored Cable

Structural features:Central tube cable(also called loose tube cables)

Optical fiber applications place:  Installed in ducts, underground conduits, aerial

Fiber optic cable types:GYXTW

Fiber Numbers:1-12 fibers

Recommended index: 5 stars

Laying fiber optic cable has been giving priority to developing countries in the world as a strategic project.

When you're laying pipes and overhead cables, and fibers number 2-12 fibers,

Recommended by the general manager of foreign trade James xu from zion communications,

You can select the GYXTW style(Central tube) to suit the applications. This is the most popular and the first choice for the ducts/aerial.

The fibers are positioned in a loose tube made of PBT. The tube is filled with a water-resistant filling compound. Two steel wire locates beside the center of core as a metallic strength member.

The cable is completed with a PE(LSZH) sheath.

Steel-polyethylene bonded sheathed cable for outdoor communication, the metal reinforcing members, center tube, fully filled, parallel steel wire


Good mechanical and temperature performance.

High strength loose tube that is hydrolysis resistant.

Special tube filling compound ensures critical protection of fiber.

Crush resistance and flexibility.

PSP enhancing moisture-proof.

Two parallel steel wires ensure tensile strength

Small diameter, lightweight, and friendly installation

Long delivery length

The properties of single-mode optical fiber (ITU-T Rec. G.652.D)

Fiber optic cable uses:

This kind of cable is generally recommended

G.652D (B1.3): Supports 10Gbit/s system transmission distance up to 3000km, 40Gbit/s system transmission distance is 80km

The attenuation coefficient is the same as that of G.652C, that is, the system can work in the 1360~1530nm band.

The zero-dispersion wavelength is at 1310 nm, and the attenuation is minimal at a wavelength of 1550 nm, but has a large positive dispersion of about 18 ps (nm/km).

G.652.D is the most rigorous and fully backward compatible of all G.652 levels and is structurally indistinguishable from ordinary G.652 fiber.

The reason for this difference is in manufacturing technology.
