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… WebDec 15, 2024 · DWDM typically has the capability to transport up to 80 channels (wavelengths) in what is known as the Conventional band (C-band) spectrum, with all 80 channels in the 1550 nm region. Allowing huge amounts of data to travel in one single network link, DWDM is ideal for long-haul transmission as the wavelengths are tightly …
WebDense wavelength division multiplexing works on the same principle as CWDM, but in addition to the increased channel capacity, it can also be amplified to support much longer distances. CWDM and DWDM wavelength comparison. The following figure shows how the DWDM channels fit into the wavelength spectrum compared to CWDM channels.
