DOI: 10.1109/lpt.2018.2868048
Abstract: A passive technique for multiplexing spectrally overlapping optical network signals is proposed and experimentally verified. The system utilizes arrayed fiber delay lines for multiplexing signal generation and offers simultaneous plotting of multiple optical spectra. Accurate… read more here.
