ОКГ
General information
U-DF2Y (ОКГ) type fiber optic cable with a central tube on which aramid yarns or glass yarns are put, single-layer-coated for cable jetting
STRUCTURAL DESIGN OF CABLE
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. Next, the core is sheathed with a high-dense polyethylene sheath (cables with high fire safety level are sheathed with LSZH compound).
