Realization of WB-based ROADM and analysis of its optical path OSNR penalty
this article discusses in detail the advantages of ROADM device
presents a realization scheme for Wavelength Blocker(WB)-based ROADM and measures the maximum OSNR penalty of this ROADM node device in relation to its practical applications.The results indicate that this device meets the requirements in applications.
