Claim 0:
1. A substrate support assembly configured to support a substrate during substrate processing in a processing chamber, the substrate support assembly comprising:
a first optical receiver embedded in the substrate support assembly to receive a first optical signal and a first optical data through a fiber optic cable;
a power converter embedded in the substrate support assembly to generate DC power based on the first optical signal and the first optical data received by the first optical receiver;
a first circuit embedded in the substrate support assembly to:
receive the DC power from the power converter; and
receive a second data from a sensor disposed in the substrate support assembly in response to the first optical data, the sensor configured to sense a parameter associated with a process performed in the processing chamber; and

a first optical transmitter embedded in the substrate support assembly to transmit the second data as a second optical data through the fiber optic cable.
