ОКЛ-Т
General information
A-D(ZN)2Y(SR)2Y/A-D(BN)2Y(SR)2Y (ОКЛ-Т) type fiber optic cables with the double sheath and armored by a laminated corrugated-steel tape for installation in cable ducts.
STRUCTURAL DESIGN OF CABLE
Optical fibers are freely placed inside the tube and interstice is filled with a gel. In addition to aramid yarns or fibers glass yarns, the central tube is sheathed with a polymer inner jacket. Internally jacketed cable core is sheathed with laminated corrugated-steel tape armor and a high-density polyethylene outer jacket. On customer’s request, water-blocking fiber or tape can be applied under the laminated corrugated-steel tape armor.
