Dwdm radiation
A WDM system uses a multiplexer at the transmitter to join the several signals together and a demultiplexer at the receiver to split them apart. With the right type of fiber, it is possible to have a device that does both simultaneously and can function as an optical add-drop multiplexer. The optical filtering devices used have conventionally been etalons (stable solid-state single-frequency Fabry–Pé… WebAug 1, 2001 · In submarine DWDM systems, special cleanup filters, separated by several EDFAs throughout the chain, remove residual ripple from the GEF-filtered EDFA gain …
