Int/Ext Midspan Cable G657B3 3.0mm Cca – White – Multiple Fibre Counts

Internal / External Midspan Cable G657B3 3.0mm Cca – White – Multiple Fibre Counts

The Internal / External Midspan Cable G657B3 3.0mm Cca – White – Multiple Fibre Counts is a compact, high-performance fibre solution designed for scalable and discreet deployment in MDU, residential and access network environments.

Available in multiple fibre counts (including 12F and 24F variants), this cable range offers flexibility for both standard and higher-density installations. Its white FR-LSZH outer sheath is ideal for internal visible routing, delivering a clean, aesthetic finish while maintaining compliance with fire safety requirements.

Engineered with water-blocking aramid yarn strength members, the cable is suitable for both indoor and outdoor installations, ensuring durability and long-term reliability. The 3.0mm compact diameter allows easy handling and discreet installation along walls, ceilings and corridors.

Utilising G.657B3 bend-insensitive fibre, the cable supports tight bend radii with minimal signal loss, making it ideal for complex routing paths and midspan access applications in multi-dwelling environments.
