Therefore, dwdm systems multiply the information-carrying capacity of a fiber by the number of wavelengths it carries. DWDM provides an indisputable increase in the capacity of long-distance optical networks, in other words, with the implementation of DWDM, the price per transmitted bit is significantly reduced in long-distance transmissions (50 km and more). 4. This is why CWDM is considered “coarse” compared to DWDM. Tunable DWDM transceivers allow you to control the wavelength (color) that the laser channel emits, adding flexibility and reducing cost. It can be loosely described as any centralized data repository which can be queried for business benefits. O-Band: 1270nm to 1370nm E-Band: 1371nm to 1470nm S. At any given data rate, DWDM optics modules have always been larger than client optics, so outfitting routers with DWDM optics meant sacrificing roughly half the capacity of the router. The features of CWDM mux Demux products: 1. The main advantage is that it increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network.
