200G DWDM 3Ports DWDM Devices
What is the introduction of DWDM?
The technology is getting more and more advanced, and the wavelength interval is getting shorter and shorter. When it reaches the level of a few nm, it becomes a compact WDM called Dense Wavelength Division Multiplexing, or DWDM (Dense WDM). The DWDM wavelength interval can be 1.6nm, 0.8nm, 0.4nm, 0.2nm, can accommodate 40, 80, 160 waves (maximum can support 192 waves). The wavelength range of DWDM is 1525nm to 1565nm (C band) and 1570nm to 1610nm (L band).
Dense WDM, also named dense WDM splitter, as well as coarse WDM splitter, is one of the commonly seen WDM device. DWDM often applied with network device such as wireless device, olt device, etc.
Product Information:
