Abstract
An apparatus and method are applied to characterizing an dispersion-affecting element for use in controlling chromatic dispersion in an optical communications link. Information regarding the behavior of the dispersion-affecting element is recorded and stored in a medium that is provided for deployment with the dispersion-affecting element to enable improved management and active control of the dispersion-affecting element. The suitability of the dispersion-affecting element for operating under different conditions may also be characterized.
Claims20
A method comprising:
- coupling an optical signal to a dispersion-affecting element of an optical commumcation system;
- applying a tuning influence to the dispersion-affecting element;
- measuring a response of the dispersion-affecting element to the optical signal;
- deriving characterization information that indicates the response of the dispersion-affecting element to the tuning influence;
- and
- in a data storage element, recording the characterization information related to the measurement.

A system comprising:
- an optical transmitter to transmit a first optical signal;
- a dispersion-affecting element to:
- receive the first optical signal, and
- output a second optical signal;
- an attenuator to apply a tuning influence to the dispersion-affecting element;
- and
- at least one analysis device to:
- receive the second optical signal from the dispersion-affecting element, and
- derive characterization information based on the received second optical signal, where the characterization information indicates a response of the dispersion-affecting element to the tuning influence.
