Abstract
A transceiver is provided for a communication network. The transceiver includes a single laser source configured to output (i) a first optical laser signal at a first wavelength, and (ii) a second optical laser signal at a second wavelength different from the first wavelength. The transceiver further includes a coherent transmitting portion configured to modulate the first optical laser signal for transmission to the communication network, and a coherent receiving portion configured to utilize the second optical laser signal as a local oscillator source.
