Underwater hybrid cable combining power conductors, Cat6 Ethernet, and single-mode fiber optic. PUR jacket for ROV and subsea systems requiring power, LAN, and fiber in one run.
This high-complexity hybrid underwater cable integrates power conductors, Cat6 Ethernet shielded pairs, and single-mode (SM) fiber optic cores in a single PUR-jacketed assembly. Designed for high-bandwidth ROV tether systems and deep-sea fiber LAN applications where the tether must simultaneously carry thruster power, on-board network traffic, and high-bandwidth fiber optic video or DWDM data to the surface.

Single-mode fiber (9/125 μm OS2) supports much longer reach at higher bandwidth. For ROV tethers exceeding 100 m and requiring >1 Gbps (e.g., 10GBASE-LR, 40G, or DWDM), single-mode is essential. Multi-mode (OM3/OM4) is limited to 10 Gbps at up to 300 m and is only suitable for short on-vehicle runs.
Single-mode fibers are placed in a gel-filled or dry loose tube inside the cable core. The loose tube allows the fibers to float freely within the tube, isolating them from tensile and bending strain in the cable. An Aramid (Kevlar) braid around the tube provides crush resistance and additional strength. The tube is then co-extruded with the power and Cat6 cores inside the PUR jacket.
