4-core single mode (G.652D) underwater fibre optic cable. PUR jacket, deep-sea rated, for high-bandwidth ROV data links and subsea optical networks.
This 4-core single-mode underwater fibre optic cable is designed for demanding subsea optical transmission applications. Using G.652D (OS2) single-mode fibres, it delivers high bandwidth at low attenuation over long cable runs -- ideal for ROV tethers, subsea observatory links, and deep-sea communication networks. The PUR outer jacket provides excellent resistance to seawater, UV, and abrasion.

Yes. G.652D single-mode fibre is fully compatible with DWDM (Dense Wavelength Division Multiplexing) systems. Multiple high-capacity channels can be transmitted on a single fibre, making this 4-core cable capable of carrying 40+ DWDM channels per fibre.
Yes. We commonly produce hybrid versions combining 4SM fibres with power conductors (e.g. 2 x 1.5mm2) in a single cable. See our fibre optic hybrid cable range or contact us with your combined requirements.
