On December 15, students graduated from the basic department T8 "High-Speed Backbone Transport DWDM Systems" (HTS DWDM), established in 2021 in Bonch-Bruevich St. Petersburg State University of Telecommunications (SPbSUT).

On April 26-29, T8 took part in the 34th international exhibition of information and communication technologies Svyaz-2022. The company's stand introduced the visitors to the latest developments in the field of communications. Some of them are announced at the exhibition for the first time:

On February 17, the official opening of "Backbone High-speed Transport DWDM Systems" (HTS DWDM) took place. It is the basic department of the T8 company. This event is the result of the University’s and T8 cooperative strategic vision of the importance of educating the next generation of communications technicians.

T8 took part in the OpenRAN Russia 2021 conference at Skoltech. In the 5G demo zone, visitors could get acquainted with the company's universal solution, which is the MS-200EC2-SX10P/Q40Q OTN aggregator for transmitting 4G and 5G client traffic to Fronthaul, Midhaul and Backhaul

T8 LLC will become a technological partner of Liberum Navitas in design and building of communications networks between Data centers. The key area of cooperation will be the design and construction of highly reliable communication networks between data-centers with the provision of broadband access to network services and other open resources. For the needs of the data centers and their clients T8 specialists will carry out work on the development of the data centers’ network design, preparation of specifications for their engineering, supply of telecommunication equipment and its following installation forming of fiber-optic communications lines with a bandwidth of 100 to 600 Gbit/s in each spectral channel.

T8 LLC together with Resources of Yamal State Governmental Agency completed work on expanding the backup backbone channel of Yamalo-Nenets regional interdepartmental telecommunication network along the Salekhard - Nadym - Pangody - Novy Urengoy - Purovsk - Gubkinsky - Noyabrsk route. The total bandwidth of the channels for the two starter complexes 2020 and 2021 amounted to 200 Gbps.

T8 company has completed work on launching communication channels of the backbone technological network for Transammiak PJSC. The transition from copper infrastructure to optical network using wavelength division multiplexing (DWDM) technology was one of the stages of a large-scale modernization of the world's longest ammonia pipeline.

Coherent communication systems have made a revolutionary breakthrough in the development of fiber-optic DWDM communication lines, dramatically increasing the bandwidth of networks and the range of non-regenerative transmission. However it was found, that lightning strikes, causing a fast state of polarization rotation of a light wave with information signal, can interrupt the operation of coherent FOCL based on aerial fiber-optic cables located in a ground wire.
