Fault-detection technique in a WDM-PON
Optics Express, 2007 We propose and demonstrate a new in-service fault-localization method for a wavelength division multiplexing passive optical network (WDM-PON). This scheme uses a tunable OTDR realized by a wavelength-locked Fabry-Perot laser diode. We successfully detect the faults both at the feeder fiber and the drop fibers.

Quantum key distribution integration with optical dense wavelength division multiplexing: a review
IET Quantum Communication, Volume 1, Issue 1, Page 9-15, July 2020., 2020 Quantum key distribution (QKD) can ensure information security between two remote parties. To commercialise QKD technology successfully, it should be integrated with dense wavelength division multiplexing optical transport. However, various challenges limit the QKD's performance in terms of the quantum key rate, quantum bit error rates, and maximum ...
