Bending-loss insensitive fiber
Single-mode optical fiber with low water peak "E3 (G657A1/G652D)" is a fiber with a reduced sensitivity to bends. The fiber is produced by vapor axial deposition method (VAD) with a quartz core alloyed with Germanium. It complies with the recommendations ITU-T G.652D and G.657A1. Supplies of colored optical fiber E3 (G657A1/G652D) are possible.

Fiber with a reduced sensitivity to bends for communication systems
Singlemode optical fiber with low water peak Е3 (G.657.A2) hybrid with advanced characteristics is a fiber with a reduced sensitivity to bends has the ability to function over the entire spectrum of optical transmission of singlemode fibers.
Production since 2021Спецификация Е3 (G.657.A2)
Cut-off Wavelength Shifted Single Mode Optical Fiber
Advanced pure silica core single mode optical fiber with low transmission losses over long distances for the construction of high-performance optical telecommunications networks such as terrestrial long-distance communication systems and submarine trunk cables with optical amplifiers.
Production since 2021Specification E2 (G654E)
Multimode graded index fiber
In a standard multimode graded index fiber the core diameter is 50 and 62,5 µm which is a bigger value than transmission wavelength. This leads to propagation of plenty of different light rays – modes – in all the three transmission windows. Two transmission windows – 850 and 1300 nm are usually used to transmit the light along a multimode fiber.
Production is planned
Non-zero dispersion-shifted single-mode optical fiber
Single-mode optical fiber with non-zero shifted dispersion and small inclination of dispersion curve is used for long-distance fiber-optic systems of data transmission with DWDM (dense wavelength division multiplexing) that work in C- and L-ranges.
Production is planned
