The Shvabe holding of Rostec State Corporation has supplied a pilot set of equipment for a fiber-optic system for transmitting and converting optical signals. Signal transmission equipment for managing the subsea infrastructure of offshore oil and gas production is planned to be installed at the production complex at the Yuzhno-Kirinskoye field on the shelf of Sakhalin Island in the Northern Pacific Ocean.

The technological solution is based on the use of fiber optics and allows data exchange at a depth of 500 meters. In terms of the speed of information transfer, this Russian equipment surpasses foreign counterparts operating by means of an electric cable.

Digital fiber-optic modules, specially designed for operation in deep water, are responsible for the speed and reliability of information transfer. In total, the system allows to connect up to 48 subsea control modules, which remotely control and monitor the production process at a distance of up to 85 km. The guaranteed service life of the system is at least 30 years.

In 2021, it is planned to complete operational tests and carry out the next delivery to an energy company operating in Russian waters.
