In a multimode fiber modal dispersion causes each mode to have a different velocity and reach to the end of the fiber at a different time. This will cause inter-symbol interference (ISI) which means that we need to send data at lower rates in order to prevent ISI. Lower rates means a reduction in bandwidth.

1. intermodal dispersion in multimode fibre but intrmodal in single mode....

2.intermodal is also known as modal dispersion but intramodal is also known as material dispersion.

3.in intermadal more pulse broadning but in intramodal less pulse broadning.

the three types of dispersion are:

1. Intermodal Dispersion

2. Chromatic Dispersion

3. Waveguide Dispersion

No. Modal is an adjective and not a verb so nobody can modal anything.

the three types of dispersion are:

1. Intermodal Dispersion

2. Chromatic Dispersion
