КС-FTTНSC Cable

Application

КС-FTTНSC- fiber optical cable with G.657A2 fiber standard is designed for aerial laying on supports, on building walls.

Cables are recommended for overhead laying from support to the building (without strength member) and outside as well.

General description

Optical fiber cable with high flexible fiber in incombustible, halogen – free, low smoky LSZH coating with integrated steel galvanized wire bearer. Optical single mode high flexible fiber is used in cable. Core diameter is 9-10 µm (Rec. ITU-T G.657A2).

Cable load-bearing elements are made in the shape of round glass-fiber- plastic bar, aramid or glass fibers, impregnated with glue composition.

Ordering information

Reference cable signs should have the following: name; КС - manufacturer’s reference name «Kazcentrelectroprovod» LPC; cable type; load-bearing element (П - glass-fiber- plastic, А – aramid; absence of signs means steel), number of cable optic fibers, ITU optic fiber standard; optic fiber manufacturer (FF – Fujikura Fiber, CF - Corning Fiber); maximum tension level in KN; coating material (PVC, LSZH, РЕ and so on).

 

Example of overhead FTTHSC cable produced by «Kazcentrelectroprovod» LPC, in incombustible, halogen – free, low smoky LSZH coating with 2 single mode optical fibers, produced by Fujikura Fiber, 0,6 кН tension, with dielectric load-bearing members made of glass-fiber- plastic.
