40 Gbit/s (4 × 10 Gbit/s) Y-00 Protocol for Secure Optical Communication and its Transmission over 120 km

Not Accessible

Your library or personal account may give you access

Abstract

WDM transmitter and receiver for physical stream cipher based on Y-00 protocol using 64-level intensity modulation are demonstrated for increasing transmission capacity. 40-Gb/s Y-00 signals are successfully transmitted over 120-km amplifier repeater transmission line.
