Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 3m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 3m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 3m Pigtail is a premium fibre optic lead-in cable designed to provide a seamless transition between external and internal fibre installations, eliminating the need for additional joints or transition enclosures.

Manufactured using G657B3 bend-insensitive single-mode fibre, the cable offers outstanding flexibility and low bend loss, making it ideal for FTTH, FTTP and broadband access networks where tight routing and confined installation spaces are common. Its innovative dual sheath construction combines a durable 5.0mm UV-resistant LSZH outer sheath for external protection with a 3.0mm CPR B2ca LSZH inner cable, enabling direct building entry while complying with stringent fire performance requirements.

Supplied with a factory-terminated SC/APC connector on a 3m pigtail, the cable delivers excellent optical performance with low insertion loss and high return loss, reducing installation time and ensuring consistent network reliability. Aramid yarn strength members, water-blocking tape and an integrated rip cord provide enhanced mechanical protection and easy cable preparation for professional fibre installations.
