Maelstrom
WiSub’s patented award-winning underwater microwave-based connector solutions have proven to be a disruptive solution creating new possibilities for the subsea industry. Maelstrom is designed with flexible mounting and a transparent Ethernet interface.
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 high-speed, high-frequency microwave electronics vs. low-frequency RF, inductive or acoustic technologies. WiSub pinless connectors are unaffected by acoustic disturbance, or by turbidity and marine growth that might affect optical systems. Electronics and tranducers are optimized for through-water transmissions. Low-frequency inductive power transfer and high-frequency data transfer solutions peacefully co-existing without interference.
Flexible Operational Tolerances
WiSub pinless connectors overcome sub-millimeter tolerances to offer centimeter tolerances on your subsea connection applications, enabling subsea solutions never before possible with pinned connectors.
