Excel OS2 Singlemode 9/125 Multi Loose Tube G.675.A1 HDPE Fca Fibre Optic Cable Black (Per Metre)

Enbeam OS2 singlemode G.657.A1 multi loose tube fibre cable is designed for external fibre optic installations in underground duct systems. It is suitable for access networks, FTTP/FTTx distribution, campus links and other outdoor telecoms routes where a water-blocked, duct-grade fibre cable is required. The cable uses multiple gel-filled loose tubes arranged around a central strength member. Water-blocking yarn and water-blocking tape provide moisture protection, with a black HDPE outer sheath for external duct environments. The G.657.A1 bend-insensitive fibre is compatible with OS2 9/125 singlemode infrastructure and standard 1310 nm / 1550 nm transmission windows. The HDPE sheath and water-blocked construction make it suitable for underground external duct routes; installers should check project CPR and internal routing requirements before taking the cable inside buildings.
