OKLm
General information
A-DF (ZN) (SR) 2Y / A-DF (BN) (SR) 2Y (OKLm) type fiber-optic cable with double sheath and armor made of corrugated laminated steel tape for laying in cable channels
STRUCTURAL DESIGN OF THE CABLE
Tubes: the optical fibers are freely laid inside and the free space is filled with hydrophobic gel. Tubes are twisted around the central force element by the SZ-twist method. The free space between the twisted tubes is filled with gel and wrapped with PETF tape. Then the conductor is superimposed, with aramid or glass yarns, together with steel corrugated laminated tape and a sheath of high-density polyethylene (in places with increased fire danger - of LSZH). At the customer's request, a water-blocking yarn or tape can be placed under the corrugated steel armour.
