Mastertel, located in St. Petersburg, has just completed a project for the construction of three underwater fiber-optic lines across the bottom of the Neva river. The lines are located near Alexander Nevsky Bridge, Annunciation Bridge and Tuchkov Bridge. As a result, the Telecommunications Provider has expanded the length and capacity of its own Master-Connect network.
The underwater construction, stretching across the Neva, interconnects the Central, Vasileostrovskiy and cultural capital of the Petrograd district. The total length of the underwater cables is 1,400 m. The underwater fiber-optic cable laying used the ĎZenithí boat along with divers and construction workers using jet-skis to carry heavy equipment. This method of cable laying was chosen because St. Petersburgís rivers are relatively free from physical obstacles (e.g. pipes, drains, etc.), which are usually associated with the presence of drawbridges in rivers of large width (300-600m).
This project is truly a unique one! As the cables are placed at the end of the existing channel, their underwater junctions and the construction of new lines are only possible with the reconstruction of the riverís embankments.
"Thanks to this project, we have created a backup line that ensures stable operation of the entire network. This means that Mastertelís customers in St. Petersburg may avail of advanced high quality telecommunications services. In addition, with the advent of the underwater channels, providing dark fibers has been made possible in any area of the northern capitalĒ, said Vladimir Kukushkin, Deputy Director Mastertel.
Note that Mastertelís venture into underwater cable laying is the first underwater telecommunications infrastructure project of its kind.
The cabling work was carried out in accordance with industry regulations, as evidenced by the project supervisorsí achievements.
