Claim 11:
12. A network computing device, comprising:
a computer processor;
a host management interface for communicating with an industry-standard small form factor pluggable optical transceiver (POT) with a plurality of dispersion compensation modules included therein, the plurality of dispersion compensation modules comprising both an electrical dispersion compensation module and an optical dispersion compensation module;
the computer processor configured to:
receive a notification of a link failure in an intensity-modulated direct-detection (IMDD) optical network which requires transitioning data communications from a first optical path of the IMDD optical network having a first chromatic dispersion characteristic to a second optical path of the IMDD optical network having a second chromatic dispersion characteristic different from the first chromatic dispersion characteristic;
determine a second set of parameters to control at least one compensation module of said POT to compensate for the effects of chromatic dispersion in the second optical path, the second set of parameters different from a first set of parameters used to control the at least one compensation module to compensate for the effects of chromatic dispersion in the first optical path; and
communicate the second set of parameters to the POT through the host management interface to reconfigure the POT to use the second set of parameters in place of the first set of parameters for dispersion compensation;

wherein the POT is configured to automatically determine at least one of the first and second set of parameters; and
wherein the computer processor is configured to provide seed values to the POT to facilitate automatically determining the second set of parameters, the seed values based on a known length of the second optical fiber or a known distance between a first POT and a second POT.
