Discreet Internal Cable 12F G657B3 2mm – Cca White – Bare – Multiple Lengths
The Discreet Internal Cable 12F G657B3 2mm – Cca White – Bare – Multiple Lengths (200m / 500m) is a high-performance fibre cable designed for discreet internal routing within multi-dwelling units (MDUs). Engineered for large-scale deployments, it enables clean, efficient and continuous fibre installation across corridors, risers and internal building pathways.
Manufactured using G.657B3 bend-insensitive singlemode fibre, this cable offers excellent flexibility with minimal bending loss, making it ideal for tight routing conditions and confined spaces. 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 combined with 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) and available in 250m and 500m reel lengths, it offers maximum flexibility for on-site termination, making it ideal for bespoke network builds and high-volume fibre deployments.
