Abstract
An optical data bus transceiver (), optical data bus system () and method () employ a disambiguation signal to resolve bit ambiguities in a summation signal on an optical data bus (). The optical data bus transceiver includes a transmitter () connected to the optical bus and configured, in conjunction with another transmitter (), to produce on the optical bus the summation signal during a first interval and the disambiguation signal during a second interval. The optical data bus transceiver further includes a receiver () configured to receive () the summation signal. The summation signal includes a summation of separate data signals from each of the transceiver transmitter () and the other transmitter (). The disambiguation signal includes information to resolve bit ambiguities in the summation signal. A bit ambiguity results from a summation of data bits in each of the respective data signals during a symbol period of the first interval.
