A single mode optic fiber with low water peak, with a reduced sensitivity to bends for communication systems E3 ﴾G657A1/G652D﴿ ALPHA Singlemode optical fiber with low water peak E3 ﴾G657A1/G652D﴿ hybrid with advanced characteristics 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 completely complies with the requirements of ITUT G.652d and exceeds ITUT G.657A1 parameters of macrobend loss and attenuation. It is a product manufactured in the Russian Federation. Double acrylic coating provides its high strength and a long service life. The fiber works in a full spectral range of different access networks, uncluding FTTH, and can be applied in long distance communications. Fiber bending resistance and improved attenuation parameters give an advantage in the application for residential networks. The quality control system of the factory confirms plug compatibility with E3 fiber ﴾G652d﴿ manufactured by "Optic fiber Systems", JSC as well as with all available on the market SMF fibers. Fiber qulitiy's compliance with Russia and international standarts is confirmed by the Certificate № SSAQ 025.1.2.0126 issued by certification agency "Kabelsert" of JSC "VNIIKP" on 08.06.2018.
