ABSTRACT:
A method for providing robust and reliable transmission of shaft encoder signals. Initially, the differentially encoded shaft encoder signals are received. The shaft encoder signals are converted into single-ended electrical signals. These single-ended electrical signals are then converted into optical signals. Finally, the optical signals are transmitted through optical conductors.
