The construction of the underwater fiber-optic transmission line Kamchatka-Sakhalin-Magadan
Public hearings were held in the administration of the Ust-Bolsheretskiy region on the implementation of the project for the construction of an underwater fiber-optic transmission line "Kamchatka-Sakhalin-Magadan", the agency for informatization and communications of Kamchatka Krai reported.
Residents of the district were familiarized with the project documentation, including the Terms of Reference and materials of the Environmental Impact Assessment (EIA). Taking into account the results of the public hearings, a unanimous decision was made to approve the implementation of the Kamchatka-Sakhalin-Magadan Submarine Fiber Optic Transmission Line Construction Project.
In 2012, design work was carried out, which was carried out by OOO Sevzapgidroproekt (offshore section) and Giprosvyaz-4 (onshore section), surveys of the seabed and coastline were completed, and design documentation for the survey of the underwater part of the shelf was issued. In 2014, OJSC Rostelecom launched a project for the construction of a submarine fiber-optic communication line of the Sakhalin - Magadan - Petropavlovsk-Kamchatsky OSS.
The new submarine line with a total length of 1841 km will link the city of Okha on Sakhalin with Magadan and Petropavlovsk-Kamchatsky and, in most cases, will prevent the use of satellite communication channels. The capacity at the first stage will be 100 Gbit / s per direction with the possibility of further increase to 8 Tbit / s. The total cost of the project is estimated at about 3 billion rubles.
Work on laying a submarine fiber-optic communication line will begin in the second decade of May 2015. The planned completion date for laying a submarine fiber-optic communication line is October 2015. The commissioning of the FPOLS is planned in the second quarter of 2016. Laying the cable along the bottom of the Sea of Okhotsk, with an actual depth of 1,2 m in the ground, will be carried out by a specialized vessel - a cable-laying ship owned by the contractor Huawei Marine.
