The bending losses were measured for each wavelength with different bending curvature radii. In addition, the critical radius of curvature was calculated for both wavelengths, it was 0.34 and 0.26 mm of wavelength 850 and 1550 nm, respectively. The results appeared that the bending loses of 1550 nm was less than of 850 nm. ER -
