FONN

VERSATILE, MULTI-PURPOSE

PINLESS SUBSEA CONNECTOR

Fonn represents the convergence of patented high-speed microwave-based data transfer technology with innovative power transfer techniques. 250 W power transfer provides a solution for many tooling applications and mid-range power requirements, facilitating new possibilities for the subsea industry.

Comparative Advantages

WiSub pinless connectors transfer data through seawater at much higher data rates than many other existing non-contact subsea communications methods, being based on WiSub-patented high-speed, high-frequency microwave electronics vs. low-frequency RF, inductive or acoustic technologies.
Advantages over legacy “plug-in” wet-mate connectors include galvanic separation, alignment freedom, immunity against seal contamination and unlimited mating cycles.

WiSub pinless connectors are unaffected by acoustic disturbance and turbidity, or by marine growth that might affect optical systems. Driving electronics and transducers are optimized for through-water transmissions. Low-frequency inductive power transfer and high-frequency data transfer solutions peacefully co-existing without interference.
