Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 2m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 2m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 2m Pigtail is a high-performance fibre optic lead-in cable designed to provide a seamless transition between external and internal fibre network installations without the need for additional joints.

Constructed using G657B3 bend-insensitive single-mode fibre, the cable offers exceptional flexibility and bend performance, making it ideal for FTTH, FTTP and broadband deployments where tight routing and confined installation spaces are common. The dual sheath construction combines a robust 5.0mm UV-resistant LSZH outer sheath for external durability with a 3.0mm CPR B2ca LSZH inner cable, allowing safe entry into buildings while meeting stringent fire performance requirements.

The cable is supplied with a factory-terminated SC/APC connector on a 2m pigtail, ensuring low insertion loss and consistent optical performance while reducing installation time on site. Aramid yarn strength members, water-blocking tape and a rip cord provide additional mechanical protection and ease of installation, making this cable ideal for professional fibre access networks.
