ОКГ-Т
General information
U-D(ZN)2Y / U-D(BN)2Y (ОКГ-Т) type fiber optic cable with single-sheath, a dielectric structure for indoor installation and cable jetting
STRUCTURAL DESIGN OF CABLE
Optical fibers are freely placed inside polymer tubes and interstice is filled with a hydrophobic gel. Reinforcing glass fiber yarns and high-density polyethylene jacket are imposed on the central tube (cables with high fire safety level are sheathed with LSZH compound).
- Optical fiber
- Hydrophobic gel
- PBT tube
- Aramid yarns (ZN) or fiberglass yarns (BN)
- Outer protective jacket
