G.657A2 bears the entire characteristics of non-dispersion shifted single-mode optical fiber and superior bending performance, which is applicable to transmission over entire wavelength from 1260nm to 1625nm. It has low macro-bending loss and even with the bending radius of 7.5mm,and the macro-bending loss at 1625nm is only 0.8 dB.
G.657A2 bending-loss insensitive single-mode optical fiber is superior to standards of ITU-T Recommendation G.652D/G.657A and IEC International Standard 60973-2-50 B1.3.
G.657A2 applies to all types of optical fiber cable especially indoor tight-buffer cable and bow-type drop cable, which is the essential part for FTTH and FTTB.
