Patent ID: 8867924

Claim:
A method, comprising: determining whether or not to operate a small form-factor pluggable (SFP) transceiver in a low power mode based on a desired reach for the SFP transceiver after a thermal electric cooler (TEC) has been effectively switched off; when the determining indicates that the SFP transceiver is to operate in the low power mode, instructing a processor of the SFP transceiver to send a signal to a TEC driver to modify an intended operation of an automatic temperature control module to set a loop gain of the automatic temperature control module to zero such that a difference between a target temperature of a laser diode of the SFP transceiver and an actual temperature of the laser diode as indicated by a thermistor of the SFP transceiver is zero to effectively switch off the TEC that controls a temperature of the laser diode of the SFP transceiver; and adjusting output target power of the SFP transceiver to operate in the low power mode.
