What are the differences between the G655C pigtail and the G652D

652D single-mode fibers have lower attenuation coefficients at 1550nm and eliminate the water absorption peak near 1380nm. These fibers can work in the 1360nm–1530nm wavelength range, supporting WDM transmission. It has G652A, B, C and D four versions. However, they are not. ITU-T G. 655 are the two options commonly used. It offers excellent transmission. G655 is known as nonzero dispersion-shifted fiber (NZDSF), because the dispersion at the wavelength of 1550 nm is close to zero but not zero. There are two types of NZDSF: (+D)NZDSF and (-D)NZDSF, the dispersion of which is respectively. There are 19 different single-mode optical fiber specifications defined by the ITU-T.
