The first phase of joint tests with “Svyaztransneft” JSC is completed

The first phase of joint tests of “Optic fiber Systems” JSC’s optical fiber for capacity of splicing with the fibers applied in communication networks of “Svyaztransneft” JSC has been completed.

Within the approved test program, optical fiber samples used in communication networks of “Svyaztransneft” JSC are being spliced with optical fiber of “Optic fiber Systems” JSC. After that the splices of optical fibers are placed into the splice closure and then checked for the temperature change exposure in a climatic chamber.    

The tests are carried out within full range of optical fiber process temperature: from -60 C to +85С. The first measurement phases showed positive results: attenuation gain at the splices placed into closure does not exceed standard values approved by the Decree No. 97 dd 17.12.1997 of State Committee for Communication and Informatization.

Let us remind you that the quality of Goods produced by “Optic fiber Systems” JSC has been many times confirmed within the tests performed by the market leaders such as Rostelecom PJSC, MegaFon PJSC, MGTS PJSC as well as by the largest cable plants.

“Optic fiber Systems” JSC  is always ready to perform testing with participation of cable plants and telecom operators in order to confirm compliance of Russian optical fiber with the established technical requirements and optical fiber applicability.


“Optic fiber Systems” JSC ( – is the first and the only Russian plant manufacturing optical fiber. The plant is situated in Saransk, Mordovia Republic. It was officially opened on 25 September   2015. The shareholders of the company are RUSNANO, Gazprombank and the Government of Mordovia Republic.

Optical fiber is the main component of optic cables for signal transmission in modern communication networks. Fiber is also used as a sensor for monitoring deformation, temperature, acoustics and other indicators.

"Optic fiber Systems" JSC produces telecommunication optical fibers of standards G652 and G 657 A1 including those with reduced diameter of 200 microns; provides services on optical fiber coloring and the application of ring marks "ringmarking". Optical fibers of new types such as G651 and G655 are being prepared for release. Products are certified in Russia and the quality is confirmed by "Rostelecom" PJSC, Russia's leading cable companies and foreign consumers.

According to the results of certification, optical fiber was approved for use on the networks of the largest Russian Telecom operators Rostelecom, MTS, MegaFon and others.

Manufacturing capacity of the plant is 4 mln kilometers of optical fiber per year.

"Svyaztransneft" JSC (   is the only network integrator and communication operator in the oil pipeline industryThe company is  a subsidiary of Transneft (Transneft, JSC before June 30, 2016). 

At present, specialists of Svyaztransneft, JSC maintain over 60 thousand km of communication lines, including communication cables with metal wiring, radio relay lines, fiber optic communication lines.
