Method for operating a multi-channel optoelectronic module
One example of a method for operating a transceiver includes selecting a first operating wavelength from a set of operating wavelengths. Next, a first control value is accessed that corresponds to the first operating wavelength. The first control value also corresponds to a first operating temperature of the transceiver, and the first operating temperature resides within a range of about 30° C. to about 50° C. Finally, the transceiver is operated substantially at the first operating temperature.
