Internal / External Midspan Cable 24F G657B3 3.0mm Cca – Black – 500m
The Internal / External Midspan Cable 24F G657B3 3.0mm Cca – Black – 500m is a high-capacity fibre cable designed for efficient, scalable deployment across MDU, residential and access network environments.
Engineered with a single FR-LSZH sheath and water-blocking aramid yarns, this cable is suitable for both indoor and outdoor installations, providing durability, flexibility and long-term reliability. Its compact 3.0mm diameter enables discreet routing while supporting high fibre density.
Utilising G.657B3 bend-insensitive fibre, the cable allows for tight bend radii with minimal signal loss, making it ideal for complex routing paths and midspan access applications. Fully compliant with CPR Cca fire performance requirements, it ensures safe installation within European building standards.
