G657A2 fiber optic cable bare fiber

Short Description:

G657A2 single-mode fibre combines two attractive features: excellent low macro-bending sensitivity and low water-peak level. It is comprehensively optimized for use in O-E-S-C-L band (1260 -1625 nm). The EasyBand^® Plus’s bending insensitive feature not only guarantees L-band applications but also allows for easy installation without excessive care when storing the fibre especially for FTTH networks application. Bending radii in fibre guidance ports can be reduced as well as minimum bend radii in wall and corner mountings.
