Stranded Loose Tube

Fiber Optic Cable

Duct or Direct Burial Application

Stranded Loose Tube Cable With Aluminum Tape and Steel Tape(Double Sheaths)

Type: GYTY53

Cores: 2~144 Cores

Fibers: G652D, G655, G657, A1a(50/125),A1b(62.5/125),OM3

Description: 

     The fibers,either of single-mode or multimode type, are placed in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire sometimes sheathed with polyethylene(PE) for cable with hight fiber count,locates in the center of core as a metallic strength member. Tubes(and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate(APL) is applied around the cable core,which is filled with the filling compound to protect it from water ingress.Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.

Characteristics:

1. Accurate fiber excess length ensures good mechanical and temperature performance.

2. High strength loose tube that is hydrolysis resistant and special tube filling compound ensure a critical protection of fiber.

3. Specially designed compact structure is good at preventing loose tubes from shrinking

4. Crush resistance and flexibility

5. The following measures are taken to ensure the cable watertight:

Steel wire used as the central strength member

Loose tube filling compound

100% cable core filling

APL moisture barrier

PSP enhancing moisture-proof

Water blocking material
