Patent ID: 7974537

Claim:
An integrated optical transceiver, comprising: an optical subassembly configured to produce a first electrical signal in response to a first optical signal and to emit a second optical signal in response to a second electrical signal, wherein the first optical signal comprises reception signal data, wherein the second optical signal comprises transmission signal data; a data processing unit in communication with the optical subassembly, wherein the data processing unit is configured to extract the reception signal data from the first electrical signal and produce the second electrical signal in response to a third electrical signal comprising the transmission signal data, wherein the data processing unit is configured to perform system-layer functions comprising media access control (MAC), Ethernet/ATM switching, or OAM message processing; a data path interface in communication with the data processing unit, wherein the data path interface is configured to send the reception data to a host device and receive the third electrical signal comprising the transmission data from the host device; a management unit in communication with the optical subassembly and the data processing unit, wherein the management unit is configured to control the data processing unit to perform the system-layer functions; and a control path interface in communication with the management unit and the host device.
