Abstract

An AWG access architecture based on reflective ONUs and a laser stack at the OLT is presented. By means of optical bursts switching, the network is capable of offering QoS and dynamic bandwidth allocation. All the network intelligence is located at the OLT, simplifying the end user equipment and reducing overall costs. The ONUs are dynamically polled by the OLT, which runs a centralized OBS protocol. Numerical analysis and network simulations have been carried out to demonstrate the performance of the proposed access scheme.
