Telenco Dual Sheath Internal/External Lead-In Cable G657A2 1F LC/APC - 125m Pigtail

Telenco Dual Sheath Internal/External Lead-In Cable – G657A2 – 1F – LC/APC – 125m Pigtail

The Telenco Dual Sheath Internal/External Lead-In Cable – G657A2 – 1F – LC/APC – 125m 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 ITU-T G657A2 bend-insensitive single-mode fibre, the cable delivers outstanding optical performance and flexibility, making it ideal for FTTH, FTTP and MDU deployments where long lead-in distances and demanding installation routes are required. Its dual sheath construction combines a robust 5.0mm UV-resistant LSZH outer sheath for outdoor durability with a 3.0mm CPR B2ca flame-retardant LSZH inner cable, allowing direct building entry while complying with modern fire safety requirements. An integrated rip cord enables quick removal of the outer sheath, while aramid yarn strength members provide excellent tensile strength and mechanical protection during installation.

Supplied with a factory-terminated LC/APC connector on a 125m pigtail, the cable provides low insertion loss and excellent return loss, reducing installation time while ensuring dependable long-term optical performance. Lightweight, flexible and easy to install, it is ideally suited to residential broadband, commercial buildings and telecommunications access networks.
