WebMar 1, 2024 · Well, an optical network terminal (or ONT) has a similar function to the retina—it converts fiber signals (light, basically) into digestible information your devices can understand. If you have a fiber internet connection, an ONT serves as an integral part of your system. Without it, your devices wouldn’t know what to do with the incoming signal. WebApr 14, 2024 · The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks, which effectively saves deployment cost. We propose an improved scheme for …
