Int/Ext Midspan Cable 12F G657B3 3.0mm Cca- Black - 500m

Internal / External Midspan Cable 12F G657B3 3.0mm Cca – Black – 500m

The Internal / External Midspan Cable 12F G657B3 3.0mm Cca – Black – 500m is a high-performance corridor cable designed for fast, reliable fibre deployment across MDU, residential and access network environments.

Constructed with a single FR-LSZH sheath and water-blocking aramid yarns, this cable is suitable for both indoor and outdoor installations, providing durability and flexibility across a wide range of applications. Its compact 3.0mm diameter allows discreet routing while maintaining excellent mechanical performance.

Featuring G.657B3 bend-insensitive fibre, the cable supports tight bend radii with minimal signal loss, making it ideal for complex routing scenarios and midspan access installations. Designed to meet CPR Cca requirements, it ensures compliance with European fire safety standards.
