Extending ethernet reach for instruments used in subsea observatories

Due to the increased use of subsea instruments for scientific research that generate large quantities of data, higher data transmission bandwidths are a necessity for subsea communications in these systems. Furthermore, there is a desire to locate scientific equipment relatively far away from the node in order to minimize the influence of the disrupted environment to the measurement being investigated. Through the ODI product line, Teledyne has developed solutions for extending the reach of conventional electrical Ethernet, while maintaining an electrical Ethernet wet-mate interface to customer equipment. With these new technologies, Ethernet step outs of up to 10 km are achievable.
