ОККМ-ОККмС
General information
A-DF(ZN)2Y / A-DF(BN)2Y (ОККм/ОККмС) type fiber optic cable with dielectric structure, single-layer coated, with aramid or fiber glass yarns for suspension on power line pylons
CABLE CONSTRUCTION DESIGN
Optical fibers are freely placed inside polymer tubes and interstice is filled with a hydrophobic gel. Polymer tubes are SZ stranded around a central-strength member. Interstice between stranded tubes is filled with hydrophobic gel and covered with PET tape. Reinforcing aramid yarns or glass fiber yarns and high-density polyethylene outer jacket are imposed on the cable core.
- Central member
- Polymer tube
- Optical fiber
- Hydrophobic gel (intramodular)
- Insulating cord
- Hydrophobic gel (intermodular)
- PET tape
