Abstract

An optical layer solution for implementing multiple secure virtual private networks (VPNs) over a passive optical network (PON) using electronic code-division multiple access is proposed. The multiple virtual private networking capability is experimentally demonstrated with 40-Mb/s data multiplexed with a 640-Mb/s electronic code that is unique to each of the VPNs in the PON, and the transmission of the electronically coded data is carried out using Fabry-Peacuterot laser diodes. Experimental results show that this technique can potentially support high data rate traffic while imposing minimal penalty resulting from optical beat interference
