Abstract:
A method for crosstalk reduction in a bidirectional optical communication link between two terminals, comprising the step of:simultaneously transmitting data in two directions over the communication link utilizing two different optical wavelengths as well as two different electrical-carrier frequencies, wherein a laser section comprising a laser source, a monitor photodetector section comprising a monitor photodetector, and a receiver photodetector section comprising a receiver photodetector are integrated in each of the two terminals to optically transmit, monitor, and receive data in a first and second direction over said communication link utilizing the two different optical wavelengths and the two different electrical-carrier frequencies, at least one of the optical wavelengths propagating through at least one of the monitor photodetector sections to be received by the receiver photodetector, the monitor photodetector section being essentially transparent to the at least one optical wavelength.
