Telenco Dual Sheath Internal/External Lead-In Cable G657B3 1F SC/APC - 10m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 10m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657B3 – 1F – SC/APC – 10m 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 tight bend radii and confined installation routes are common. Its innovative dual sheath construction incorporates a durable 5.0mm UV-resistant LSZH outer sheath for external protection and a 3.0mm CPR B2ca LSZH inner cable, allowing direct building entry while meeting stringent fire safety requirements.

Supplied with a factory-terminated SC/APC connector on a 10m 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 provide enhanced mechanical protection and simplify installation in professional fibre optic deployments.
