ABSTRACT:
A method of measuring mode dispersion in a transmitting optical fibre for transferring light signals representing digital information coded according to a binary line code. The clock signal amplitude is first measured in the system receiver with the pertinent transmission fibre connected and thereafter with the system loop-connected. The dispersion can be calculated from both measured amplitude values.
