Production started in 2016. A standard single-mode fiber is a thin (5-8 µm) core made of glass alloyed by Germanium surrounded by a thicker layer of pure glass.Specification E3 (G652d)
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 will start in 2017
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 will start in 2018
Bending-loss insensitive fiber
The fiber described in ITU-T G.657 recommendations allows very small bending radius (up to 7,5 mm) and is used for indoor installations.
