The deployment of translucent optical networks is considered the most promising short term solution to decrease costs and energy consumption in optical backbone networks. In fact, translucent Wavelength Switched Optical Networks (WSONs) have recently received great attention from the research community due to their technological maturity. However, the inflexibility and coarse granularity of WSONs is (re-)fostering research interest in sub-wavelength switching technologies such as Optical Burst Switching (OBS). In OBS, however, the majority of research works neglect the impact of physical layer impairments by considering either fully transparent (i.e., with optical 3R regeneration) or opaque (i.e., with electrical 3R regeneration) networks.
