G657A1 Bending insensitive single-mode fibre has the characteristics of dispersion-unshifted single-mode fibre (G652D) and good macrobending resistance. It is a bend insensitive low water peak fiber, and comprehensively optimized for use in O-E-S-C-L band (1260~1625nm). Because of its minimum bending radius up to 10mm, this fiber is suitable for high density or small space application.
