Match the following

Intermodal Dispersion

The time delay difference resulting from different propagation velocities of two optical signals with different cross polarization states

Polarization Mode Dispersion (PMD)

The dispersion generated by the different time delays from different signals with different frequencies (or wavelengths) during their transmission over the same optical fiber

Chromatic Dispersion (CD)

The time delay difference resulting from different modes (incident angles) that have different group velocities

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.
