Abstract

Wavelength stabilization of transmitters is required in a wavelength-division-multiplexed (WDM) network to avoid channel cross talk and received signal drop-out. However, transmitter-wavelength stabilization requires additional complexity within each node. The cost of implementing and maintaining this wavelength-stabilization complexity is significant in packet-switched networks.¹ Additionally, network-wide wavelength alignment requires a common broadcast channel or an absolute wavelength reference.²
