Abstract

The crosstalk penalty on the performance of optical satellite networks with wavelength-division-multiplexing (WDM) architectures is analyzed and quantified. The crosstalk is generated due to imperfection of the wavelength filtering devices at the wavelength router onboard a satellite node, when several optical WDM intersatellite links (ISLs) arrived and their channels are recombined though demultiplexer/multiplexer pairs, then they are transited. The Doppler wavelength shift is introduced to the ISLs. It causes the fluctuation to the system power penalty. The worst case of the system power penalty is used to analyze satellite networks with multihop ISLs, and crosstalk specification of wavelength filtering devices is given for the different number of multihop ISLs. This work contributes heuristically to the design of constellation networking with WDM Laser ISLs architectures.
