The optical transceiver module includes a housing and a plurality of
components disposed at least partially within the housing. The components
include an optical transmitter, an optical receiver, and a power
controller integrated circuit (IC). The power controller IC is
electrically coupled to at least one of the plurality of components. The
power controller IC is configured to perform power supply functions for
the optical transceiver module. Also, the power controller IC includes
multiple voltage regulators providing power to the components at two or
more voltages.
