… Abstract: To provide dedicated downstream and upstream transmission with direct ONU
interconnection, a WDM-PON architecture is proposed. This offers efficient bandwidth …

… ONU for providing interconnection simultaneously. Thus, all the ONUs also can result in a
virtual private network (VPN) in the presented WDM-PON. … In the WDM-PON, the downstream …

… direct optical network units (ONUs) interconnection. Broadcasting downstream transmission
is … Direct ONU interconnection is accomplished by separating the inter-ONU signal from the …

… ONU communication approaches in WDM-PON have been reported. Some approaches
reported broadcasting in which data from source ONU … in which source ONU is sharing the data …

… This paper proposes a distinctive tree architecture supporting flexible ONU interconnection
with high wavelength utilization. This architecture creatively introduces a novel PN. Together …
