ROV umbilical twisted pair tether

Derul Cable is able to design and manufacture Remotely Operated Vehicle (ROV) tethers. Power & signals are integrated into a cable structure, so ROV tethers can be used to transmit both electricity and signal. ROV tethers normally resort to coaxial and twisted pairs to achieve signal transmission. The cable which connects the underwater vehicle with the controller significantly affects its performance, so it must ensure stable signal transmission. The neutrally buoyancy helps vehicle run smooth with less water resistance and loading.
