Abstract (in Japanese) (See Japanese page) 
(in English) To process the ever-increasing network traffic cost-efficiently, the spectral efficiency of photonic networks must be increased. This is possible with higher-order modulation formats, ultra-dense wavelength-division multiplexing (WDM), and/or elastic optical networking. However, such spectrally efficient systems are more susceptible to transmission impairments such as fiber nonlinearity in links and spectrum narrowing at nodes, which limits the available transmission distance and node-hop count. Therefore, distance-adaptive modulation cannot directly be applied to ultra-dense WDM. In our developed grouped routing network, express paths are routed in a bundle and add/drop operations are done in a path-by-path manner, which can limit the number of spectrum narrowing time while realizing ultra-dense WDM. In this paper, we confirmed the effectiveness of grouped routing networks with distance-adaptive modulation by extensive computer simulations.
