Jupiter Io - Subsea Fast Ethernet Switch and Data Multiplexor


The leaders in subsea control

Zetechtics are world leaders in subsea control systems for ROV Intervention tooling to the oil and gas energy markets, providing proven industry solutions many of which are continually working in high integrity applications.



Jupiter Io provides all the functionality of a high specification 24 Port Fast Ethernet Managed Switch, but 4000m subsea.

Data connection to the surface is over dual redundant 1Gb fibres. In addition Jupiter Io provides data conversion for video signals, RS232, RS422 and RS485. Other interfaces are available on request.

Jupiter Io operates from 24V DC or 115V AC, is 4000m depth rated, and requires no expensive special surface rack as the fibres terminate to conventional COTS Fast Ethernet Switches fitted with bi-directional SFP modules. This integrates the subsea equipment with the surface network.

Jupiter Io can also act as a Subsea Hub allowing absolutely standard Jupiter units to be connected together for larger or more complex control systems. This removes the need for custom designed Master / Slave units operating in a daisy chain.
