Hybrid WDM/TDM PON based on bidirectional reflective ONUs offering differentiated QoS via OBS

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… CONTINUE READING
