The siberian branch of Svyaztransneft (Tomsk) has built a fibre-optic transmission line, which will provide all types of process and urgent operational communications for the Aleksandrovskaya – Anzhero-Sudzhensk oil trunk pipeline of Transneft Central Siberia.
Work began in October 2016 as part of the construction of Transneft’s unified information system (UIS) for the UIS project named “High-Speed Communication Line in the Demyansk – Tomsk Section. Phase 3”. Currently, the planned 968 km of fibre-optic cable with a capacity of 48 optical fibres have been laid across the territories of Kemerovo Region, Tomsk Region and Khanty-Mansi Autonomous Area — Yugra. More than 120 crossings through natural and artificial obstacles were made.
Process equipment was installed at 23 communications centres of Svyaztransneft, 16 facilities of Transneft Central Siberia’s business units and at 61 OTP control and monitoring stations (CMSs). Four additional tower type antenna-mast structures with a height of 44 to 74 m were built to eliminate poor reception areas.
The FOCL network’s planned traffic capability is over 40 Gbit/s, and it can be increased to 100 Gbit/s if necessary. The high FOCL traffic capability is guaranteed by the Dense Wavelength Division Multiplexing (DWDM) technology and by arranging a synchronous digital hierarchy (SDH) transmission system of various transport levels from STM-1 to STM-64.
The commissioning of the new FOCL will provide consumers of the services with high-speed broadband communication channels and modern multi services; integration with the existing radio-relay lines of the branch will permit full redundancy.
