Abstract
Messages on controller area net work (CAN) buses are communicated over subsea optical links. An adaptor couples a CAN bus to an optical link. The adaptor detects a direction of transmission, that is, whether a signal began on the CAN bus coupled to the adaptor or on the optical link coupled to the adaptor. Signals from the CAN bus are conditionally transmitted to the optical link depending on the detected direction of transmission. The adaptor can operate at the physical layer without analyzing contents of the CAN bus communications.
