Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 250m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 200m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 200m Pigtail is a premium fibre optic lead-in cable engineered to provide a seamless transition between outdoor and indoor fibre installations without the need for additional joints or transition enclosures.

Manufactured using G657B3 bend-insensitive single-mode fibre, the cable delivers exceptional optical performance and superior flexibility, making it ideal for FTTH, FTTP and broadband access networks where extended lead-in distances and demanding installation routes are required. Its innovative dual sheath construction combines a durable 5.0mm UV-resistant LSZH outer sheath for external protection with a 3.0mm CPR B2ca flame-retardant LSZH inner cable, allowing direct building entry while complying with stringent fire safety requirements. The integrated rip cord enables quick removal of the outer sheath, while aramid yarn strength members provide excellent pulling performance and mechanical protection.

Supplied with a factory-terminated SC/APC connector on a 200m pigtail, the cable offers low insertion loss and high return loss for reliable, long-term optical performance. Its lightweight construction and robust design help reduce installation time, making it an ideal solution for professional FTTH, MDU and fibre access network deployments.
