Patent ID: 7359643

Claim:
An optical transceiver module, comprising: a transceiver housing; a plurality of components disposed at least partially within said transceiver housing, said components including: an optical transmitter; and an optical receiver; a power controller integrated circuit (IC) electrically coupled to at least one of said plurality of components, where said power controller IC is configured to perform power supply functions for said optical transceiver module and said power controller IC includes multiple voltage regulators configured and arranged to provide power to said components at two or more voltages; a main controller integrated circuit (IC) positioned within the transceiver housing and electrically coupled to said optical transmitter, said optical receiver and said power controller IC; a host serial interface coupled directly to the main controller IC, the host serial interface including both clock line and data line interfaces configured to enable communication between the host serial interface and an external host; and an internal serial bus to which the main controller IC and the power controller IC are connected in parallel.
