OPTICAL CHANNEL MONITOR FOR A WAVELENGTH SELECTIVE SWITCH EMPLOYING A SINGLE PHOTODIODE |
摘要 |
A method of monitoring at least one optical wavelength component of a WDM optical signal being routed through a wavelength selective switch (WSS) includes directing an optical wavelength component from a given input port of the WSS to a selected output port with a selected amount of attenuation. A rejected portion of the optical wavelength component giving rise to the selected amount of attenuation is directed to an optical monitor associated with another output port of the WSS. A power level of the optical wavelength component is determined by pre-calibrating a proportionality between the power level of the wavelength component and the power level of the rejected portion that is directed to the optical monitor. |
