Abstract
A method of measuring accumulated chromatic dispersion in an optical data transmission network includes the following method steps: a) sending a first bit pattern with at least one first pulse at a first wavelength and a second bit pattern with at least one second pulse at a second wavelength over an optical fiber; b) receiving the first bit pattern and the second bit pattern; c) determining a relative temporal shift between the first bit pattern and the second bit pattern; and d) calculating the accumulated chromatic dispersion from the relative temporal shift.

A method of measuring accumulated chromatic dispersion in an optical data transmission network, the method comprising:
- a) sending a first bit pattern having at least one first pulse at a first wavelength and a second bit pattern having at least one second pulse at a second wavelength over an optical fiber;
- b) receiving the first bit pattern and the second bit pattern;
- c) determining a relative temporal shift between the first bit pattern and the second bit pattern;
- and
- d) calculating the accumulated chromatic dispersion from the relative temporal shift.
