摘要：

The objective of this study is to exploit the existing trade-off between the fiber link wavelength count and achievable circuit optical signal-to-noise ratio (OSNR) in Wavelength Division Multiplexing (WDM) networks. Each fiber link is assigned a specific OSNR-driven Spectrum Assignment (OSA) constraint, defined as the maximum number of active wavelengths the link is allowed to concurrently provision. By constraining the number of active wavelengths (where applicable) each wavelength can be assigned a larger fraction of the optical amplifier-provided (finite) total power budget on that link. The study shows that by properly choosing the OSA constraint for each fiber link in the network, it is possible to increase circuit OSNR without adversely affecting the network ability to accept traffic requests. In turn, increased circuit OSNR permits bandwidth-efficient modulation schemes to be used and/or improves signal robustness. Achievable OSNR gains are estimated through simulation using both an ideal optical amplifier model and a realistic erbium-doped fiber amplifier (EDFA) model accounting for uneven gain and noise.(1)
