Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 2.5m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 2.5m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 2.5m Pigtail is a premium fibre optic lead-in cable designed to provide a seamless transition between external and internal fibre installations without requiring additional joints or transition boxes.

Manufactured with G657B3 bend-insensitive single-mode fibre, the cable delivers outstanding flexibility and optical performance, making it ideal for FTTH, FTTP and broadband access networks where tight bend radii are often required. The innovative dual sheath construction combines a robust 5.0mm UV-resistant LSZH outer sheath for outdoor durability with a 3.0mm CPR B2ca LSZH inner cable, allowing direct entry into buildings while meeting stringent fire safety requirements.

Supplied with a factory-terminated SC/APC connector on a 2.5m pigtail, the cable provides low insertion loss and excellent return loss, reducing installation time and ensuring consistent network performance. Featuring aramid yarn strength members, water-blocking tape and an integrated rip cord, it is built for reliable installation in demanding telecommunications environments.
