Abstract
A Wavelength Division Multiplexing (WDM) transceiver includes a Wavelength Multiplexer/Demultiplexer (WM/D) having a plurality of inputs (N) and N Amplified Light Emitting (ALED) devices, each ALED device transmitting a wideband optical signal to and receiving an optical signal from a different one of the N inputs of the WM/D transceiver. During transmission, the WM/D selects different wavelengths from ALED signals at each of the N inputs and multiplexes them together into a combined signal at its output. During receiving, the WM/D demultiplexes different wavelengths from a signal received at its output and sends the different wavelengths to each of the N inputs. A WDM system is formed using two WDM transceivers which are connected over an optical link and which alternately transmit and receive signals.
