Abstract
An optically amplified back-up receiver includes an optical splitter for receiving a wavelength division multiplexed (WDM) optical communications signal by splitting the signal into a low power WDM optical signal onto a back-up path where it is amplified and an optical signal of desired wavelength selected. A PIN detector receives the optical signal at the desired wavelength and converts the optical signal into an electrical communications signal.
