Paper Abstract

We present and demonstrate a unique type of secure key distribution utilizing ultra-long fiber laser (UFL). A 500km long secure key distribution link based on Raman gain UFL is demonstrated experimentally. An error-free distribution of a random key with an average bit-rate of 100Hz between the users is demonstrated and the key is shown to be unrecoverable to an eavesdropper employing either time or frequency domain passive attacks.
