General information
A-DQ (ZN) 2Y (SR) 2Y/A-DQ (ZN) 2Y (SR) 2Y (OKL) type fiber optic cable with double sheath and armor made of corrugated laminated steel tape (dry structure) for laying in cable channels
THE STRUCTURAL DESIGN OF CABLE
Tubes: the optical fibers are freely laid inside, and the free space is filled with hydrophobic gel. The central power element based on the dielectric is covered with water-blocking yarns; and the tubes are twisted around it by the SZ-twist method. A water-blocking tape is applied onto the twisted tubes, and an inner sheath - onto the tape. An armor made of steel corrugated laminated tape and an outer sheath made of high-density polyethylene are placed on the cable covered with an inner sheath. At the customer's request, a water-blocking thread or tape can be placed under the corrugated steel armor.
