We used a commercial QKD system to conduct key exchange over 50-km fiber span that supported classical 10 Gbit/sec traffic. Both quantum and classical channels were carried by the standard ITU grid C-band wavelengths.
Traffic will undoubtedly continue to grow, but it is important to put this into perspective. This presentation will categorize growth rates and propose cost effective solutions in Access, Metro and Long Haul without the need to replace existing fiber.
We monitored the state of polarization (SOP) of polarized light in an optical ground wire (OPGW) link located in North America using a test method and apparatus that measured Stokes space angular velocity and geographic location of SOP transients. We observed transients up to 5.1 Mrad/s and were able to correlate these events in both time and location to lightning strikes documented by the United States Precision Lightning Network (USPLN).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
