Cutoff Wavelength Shifted Single Mode Optical Fiber E2 (G654E)
Cutoff wavelength shifted Single Mode Optical Fiber E2 (G654E) is manufactured with preforms obtained by vapour axial deposition (VAD). The fiber complies with ITUT G. 654.E. Shifted dispersion and cutoffshifted optical fiber with very low loss (CSF), can be used in longdistance digital transmission applications such as terrestrial longdistance communication systems and submarine trunk cables with optical amplifiers.The product is manufactured in the Russian Federation, fully meets the requirements of the Russian Government Decree No. 719 dated July 17, 2015, the Russian Government Decree No. 925 dated September 16, 2016. When used in a domestically produced cable, it allows to receive a 30% preference for purchases by Federal Law No. 223 comparing with imported analogs. Geometric and optical characteristics (attenuation, cutoff wavelength, chromatic dispersion, etc.) and mechanical characteristics of the product allow the use of fiber in the marine and coastal optical lines design, as well as, if necessary, the use of optical fibers that provide maximum transmission distance by the use of optical power high levels.
