Internal / External Midspan Cable 12F G657B3 3.0mm Cca – White – 500m
The Internal / External Midspan Cable 12F G657B3 3.0mm Cca – White – 500m is a compact, high-performance fibre solution designed for efficient and discreet deployment across MDU, residential and access network environments.
Built with a single FR-LSZH sheath and water-blocking aramid yarns, this cable is suitable for both indoor and outdoor installations, offering durability and consistent performance. The white outer sheath is ideal for visible indoor routing, delivering a clean and professional finish.
Featuring 12 bend-insensitive G.657B3 fibres, the cable supports tight bend radii with minimal attenuation, making it ideal for complex routing paths and midspan access applications. Its 3.0mm compact diameter enables easy handling and discreet installation within corridors, risers and internal building spaces.
