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.

Abstract: The system and method of the present invention is operative to monitor the performance of an optical communications channel. An optical splitter splits a wavelength division multiplexed (WDM) optical communications signal into a low power WDM signal onto a back-up path, where a tunable filter sweeps the optical communications channels, while a monitoring circuit monitors the optical communications channels for performance. Optical power can be stored and subsequently displayed, providing an optical spectrum analysis of the signal.

Abstract: An integrated, optically amplified receiver includes an optically pumped optical preamplifier for receiving, generally, wavelength division multiplexed optical communication signal over an optical communications line. A PIN photodetector receives the optical communication signal as a filtered demultiplexed signal from the optical preamplifier and converts the optical communication signal into an electrical communication signal. An amplifier circuit amplifies the electrical communication signal for digital retiming or demodulation. A housing or printed circuit card assembly contains the optical preamplifier, filter or demultiplexer, PIN photo detector and amplifier circuit as an integrated receiver unit.
