Optical VPN Connecting ONUs in Different PONs

Category: Security, Networking and Communications

Overview All optical Virtual Private Network (VPN) in a Passive Optical Network (PON) provides dedicated optical channels to connect VPN users. It is an effective technique to increase the throughput and reduce the latency of the network, while providing enhanced security for users. Several schemes based on waveband or wavelength reflection in a PON have been reported recently, and other proposals used star couplers for inter-connecting Optical Network Units (ONUs). In these demonstrations, the optical VPN connects ONUs within the same PON. In practice, however, there exist applications where an optical VPN is desired to connect ONUs in different PONs, in order to provide more efficient access service covering a wider area.
