Rostec has improved the production of optical fiber

2023: Upgrading Optical Fiber Manufacturing Equipment

Experts of the Shvabe holding of Rostec State Corporation have modernized equipment for the production of optical fiber. This made it possible to create samples with improved characteristics that ensure high signal transmission quality. Improved products can be used in quantum communication systems in various industries. Rostec announced this on October 31, 2023.

The research was carried out by specialists of the State Optical Institute. S.I. Vavilov (NPO GOI). They improved the exhaust tower of the production line and its components, and also revealed optimal modes of stretching twisted microstructured optical fibers. As a result, the most favorable conditions were established on the production lines: furnace temperature, exhaust speed, rotation, pressure and others.

The optical fibers being developed are quite complex, from the point of view of practical implementation, structure. The modernization of production has already proven its effectiveness - we managed to produce a series of prototypes with a high-intensity longitudinal twist of 790 revolutions per meter. At the same time, this technology will allow creating a fiber with an extremely induced twist of up to 1000 revolutions per meter, which will significantly improve the quality of signal transmission, "said Kirill Samsonov, interim director general of NGO GOI.

Quartz twisted microstructured optical fibers are of interest for a number of practical applications in various fields of fiber optics and photonics and can be used as sensors of fiber-optic sensors for recording mechanical influences, magnetic field of electric current, like mode filters, etc. Optical fibers differ in signal transmission quality, have special optical and mechanical characteristics, therefore they can be used in quantum communication systems to generate and transmit orbital angular moments.
