Discreet Internal Cable 12F G657B3 2mm – Cca White – Bare
The MDU Discreet Internal Cable 12F G657B3 2mm – Cca White – Bare is a high-performance fibre cable designed for discreet internal routing within multi-dwelling units (MDUs). Engineered for simplicity and efficiency, it supports fast and reliable installations across corridors, risers and internal building pathways.
Manufactured using G.657B3 bend-insensitive fibre, the cable offers excellent flexibility with minimal bending loss, making it ideal for tight routing conditions and confined installation environments. Its compact 2–3mm profile ensures a low-visibility installation while maintaining high optical performance.
The cable features a FR-LSZH (Flame Retardant Low Smoke Zero Halogen) outer sheath and water-blocking aramid yarn strength members, providing durability, fire safety compliance and suitability for both indoor and limited external routing.
Supplied as a bare cable (unterminated), it offers maximum flexibility for on-site termination, making it ideal for bespoke installations and network builds.
