Single mode underwater fibre optic cable with Kevlar braid reinforcement. PUR jacket, high tensile for deep ROV fibre tether deployments. G.652D fibres, custom count.
Combining the optical performance of single-mode G.652D fibres with the structural strength of a Kevlar (aramid) braid and the durability of a PUR jacket, this underwater fibre cable is engineered for ROV tether applications where the cable must simultaneously serve as the data link and the structural tether. Ideal for deep-sea deployments where high bandwidth, low latency, and tensile reliability are all critical.

Single-mode fibre supports 10 Gbps and beyond with appropriate SFP+ transceivers, enabling real-time 4K video, full-duplex sensor data, and control communications simultaneously. Over tether lengths of 100--3,000 m, single-mode fibre vastly outperforms copper alternatives.
Yes. The gel-filled loose tube construction ensures that hydrostatic pressure does not cause micro-bending losses in the fibre. At depths up to 6,000 m, the optical performance is maintained within specification.
