Hybrid WDM/TDM passive optical network with dynamic virtual PON (VPON) capability

We propose a novel hybrid WDM/TDM-PON with dynamic Virtual PON (VPON) capability. ONUs in the network can dynamically form a virtual TDM-PON to increase bandwidth and optimize network resource. The VPON is achieved without using additional lasers and tunable lasers. Experiment of 10-Gb/s downstream and 1.25-Gb/s upstream transmissions verifies the proposed scheme.
