Indoor (B2Ca) tube with 1...4 optical fibers

Indoor (B2Ca) tube with 1...4 optical fibers

Description

Description

Standards

IEC 60794; IEC 60793

This cable consists of an LSZH tube containing 1 to 4 optical fibers, reinforced with aramid yarns for mechanical strength. It is protected by a white LSZH outer sheath, designed for indoor use, and includes a ripcord beneath the sheath for easy access during installation. The cable meets the high fire performance requirements of CPR Class B2Ca. It is available in different fibre color codes.
