Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 50m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 50m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 50m 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 outstanding flexibility, making it ideal for FTTH, FTTP and broadband access networks where long lead-in distances and tight 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 LSZH inner cable, allowing direct building entry while complying with stringent fire safety regulations.

Supplied with a factory-terminated SC/APC connector on a 50m pigtail, the cable provides excellent return loss and low insertion loss, reducing installation time while ensuring reliable, long-term network performance. Aramid yarn strength members, water-blocking tape and an integrated rip cord offer enhanced mechanical protection and simplify cable preparation, making this cable an ideal solution for professional fibre access deployments.
