Description:
G657A2 bending insensitive singlemode fiber 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 bending insensitive
feature not only guarantees L-band applications but also allows for easy installation without excessive care when storing the
fiber especially for FTTH networks application.
