Methods and systems for fiber optic communication

A method of tuning a fiber optic communication system comprising the steps of:

• (a) generating a source signal X;
• (b) pre-distorting said source signal X by applying at least one pre-distortion equalizer to said source signal X to generate a pre-distorted signal XiP;
• (c) transmitting said pre-distorted signal XiP over an optical channel to generate a transmitted signal Yi;
• (d) post-equalizing said transmitted signal Yi by applying at least one post-equalization equalizer to said transmitted signal Yi to generate a post-equalized signal Zi;
• (e) evaluating said post-equalized signal Zi to determine a performance of said fiber optic communication system;
• and
• (f) when said performance of said fiber optic communication system fails to meet a predefined threshold, updating said at least one pre-distortion equalizer and repeating steps (b)-(f),
• wherein i represents an index tracking each cycle of performing said steps (b)-(f).
