Match the following
G.652
This fiber is called dispersion shifted fiber (DSF). It has zero-dispersion at 1550nm to match the minimum attenuation window of the fiber. But it has strong non-linear effects.
G.655
This fiber is also know as non-zero dispersion shift (NZDSF). Therefore, there is certain dispersion of around 4 ps/nmkm at 1550nm that is close to the one of G.653 but without the problem of strong non-linear effects.
G.653
This fiber is the widely used single-mode fiber (SMF). It has around of 17 ps/nmkm at 1550nm. It is also called dispersion-unshifted fiber.
