Telenco Dual Sheath Internal/External Lead-In Cable 1F SC/APC – Multiple Lengths

Telenco Dual Sheath Internal / External Lead-In Cable 1F SC/APC – Multiple Lengths

The Telenco Dual Sheath Internal / External Lead-In Cable 1F SC/APC – Multiple Lengths is a high-performance drop cable engineered to simplify outdoor-to-indoor fibre transitions in FTTH deployments.

Designed with a dual-sheath construction, the cable features a robust 5.0mm UV-resistant LSZH outer jacket for external protection and a 3.0mm flame-retardant LSZH inner cable for safe indoor routing. This ensures full compliance with CPR B2ca fire standards, making it suitable for installations that transition directly into customer premises.

At its core, the cable uses G.657B3 bend-insensitive singlemode fibre, allowing for tight routing with minimal signal loss, even in confined or complex environments. A pre-terminated SC/APC connector provides fast, reliable connections, while the integrated rip cord enables quick removal of the outer sheath during installation.

Lightweight, flexible and durable, this cable is optimised for efficient installation, reduced labour time and consistent optical performance across transition points.
