Abstract :
In this paper, we report an experimental implementation of quantum noise protected data cipher system using weak coherent light field based on an all-fiber dual unbalance beam Mach-Zehnder interferometer. The secure communication can be realized with a 450kb/s modulation rate over 27 km of optical fiber.
