Claim 0:
1. A method for controlling dispersion compensation, comprising:
selecting at least one dispersion compensation module of a plurality of dispersion compensation modules included within an industry-standard small form factor pluggable optical transceiver (POT) to be initialized, wherein the plurality of dispersion compensation modules comprise both an electrical dispersion compensation module and an optical dispersion compensation module;
causing a first set of parameters to control the selected at least one dispersion compensation module to compensate for the effects of chromatic dispersion in a first optical path having a first chromatic dispersion characteristic;
receiving by a host network computing device a notification of a link failure in an optical network which requires transitioning data communications from the first optical path to a second optical path having a second chromatic dispersion characteristic different from the first chromatic dispersion characteristic;
determining by the host network computing device a second set of parameters different from the first set of parameters to control the at least one dispersion compensation module to compensate for the effects of chromatic dispersion in the second optical path; and
using the host network computing device to communicate with the POT through a 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;
wherein the host network computing device provides 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.
