GYTA53 Armoured Double Jacket 12Core 24Core Rodent Resistant Optical Fiber Cable
Description
GYTA53 is one of structure for double jacket double Armored Rodent Resistant. The fibers, 250μm, are positioned in a loose tube made of a high
modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with
high 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. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath
is applied. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
Feature
- Good mechanical and temperature performance
- High strength loose tube that is hydrolysis resistant
- Special tube filling compound ensure a critical protection of fiber
- Crush resistance and flexibility
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
