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

Internal / External Midspan Cable 24F G657B3 3.0mm Cca – Black – Multiple Fibre Counts

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

Available in multiple fibre counts (including 12F and 24F variants), this cable range provides flexibility for both standard and higher-density installations. Its single-sheathed construction with FR-LSZH outer jacket and water-blocking aramid yarns ensures durability and reliability in both indoor and outdoor applications.

With a 3.0mm compact diameter, the cable supports discreet routing while maintaining strong mechanical performance. The use of G.657B3 bend-insensitive fibre enables tight bend radii with minimal attenuation, making it ideal for complex routing paths and midspan access deployments in multi-dwelling environments.
