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.
