Single Armor Single Jacket Central Loose Tube Waterproof Outdoor Cable- GYXTW
These central loose tube optical fiber ribbon cables are suitable for installation in aerial or duct environment for communication between bureaus, metropolitan network, access network and is especially suitable for the situation where high-density fibers is expected.
The tube is wrapped with a layer of PSP longitudinally,excellent crush-resistant performance. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape,to ensure tensile strength. The cable is completed with a single polyethylene (PE) sheath.
Cable Structure

Features
Light weight, small diameter, easy to lay. Good mechanical and temperature resistant performance. Low dispersion and attenuation. The centrally-situated loose tube minimizes the influence of lateral crush. Good moisture-resistance, water blocking, and flexibility. Two parallel steel wires ensure tensile strength. Good Tensile Strength and Crush Resistance performance, but a little inferior than GYXTW53.
| | Application
Laying modes: Aerial & Conduit/Duct. Bureaus network. Metropolitan network. Access network

Package
 |  |
| Package 1 | Package 2 |
Package 1: usually for indoor cable, light weight cables.
Package 2: usually for outdoor cable, heavy weight cables
Usually for each roll, the cable length is 2km, but we could provide customized package for different cable lengths. |
Mark
Usually we only attach Test Report on the out package of the cable, but we could also mark as your requirements, such as:
1. Company Name
2. Cross /Net weight
3. Drum No: XX
