The First in Russia
"Optic Fiber Systems" JSC was registered on February 18th, 2008. The investors of the company are “Gazprombank” JSC, “RUSNANO” Corporation, the Government of the Mordovia Republic. The authorized capital of the company is 3,6 billion rubles.
The main goal of "Optic Fiber Systems" JSC is the implementation of the project to found the first optical fiber production plant in Russia. The project involves industrial production of telecommunication and technical optical fiber, introduction in the production process of the latest achievements in nanostructures creation in the optical fiber and use of nanotechnologies for improvement of the fiber parameters. Production capacity of the plant is 2,4 million kilometers of optical fiber per year.

1. Optical fiber drawing
The structure of the future fiber lies in the fiber preform. The preform is loaded into the furnace upstairs drawing tower. When preform heats to a temperature of about 2000 ° C, the optical fiber is drawn preserving initial structure. At a speed of 1500 m/s (90 km/h) the fiber is cooled, two-layer acrylate coating is applied using the "wet-to-wet" method, coatings are cured, and fiber is wound on process spool. Spools are changed without drawing process stop.
2. Fiber rewinding under tension
Rewinding fiber from technological to commercial spools takes place under tension of 0.82 GPa. Thus, the fiber is tested for strength.
3. Quality control
At this stage, all optical characteristics tests are carried out.
To protect against all hydrogen exposure fiber is treated in an atmosphere of deuterium.
