Abstract
A single-fiber bidirectional optical transmission apparatus, a wavelength division multiplexing device, and an optical transmission system, is disclosed. The single-fiber bidirectional optical transmission apparatus includes: a first single-light-source coherent optical transceiver, configured to: receive a first optical signal from a first multiplexer/demultiplexer, convert the first optical signal into a first electrical signal, and send the first electrical signal to a first client signal processing apparatus; and a second single-light-source coherent optical transceiver, configured to: receive a second electrical signal from the first client signal processing apparatus, convert the second electrical signal into a second optical signal, and send the second optical signal to the first multiplexer/demultiplexer. A wavelength of the second optical signal is different from a wavelength of the first optical signal.
