Design principles for multi-hop wavelength and time division multiplexed optical passive star networks

Proposes a graph model called the receiving graph model to describe optical networks where passive star couplers are used to interconnect stations, each of which has one fixed wavelength transmitter and one fixed wavelength receiver, and wavelength- and time-division multiplexing (WTDM) protocols are employed. Based on the model, the inherent characteristics of such WTDM networks can be fully understood and alternative designs can be compared. The authors discuss several design principles and present some theoretical performance limitations for the networks
