This paper focuses on converged optical-wireless 5G infrastructures and proposes the novel concept of “Dis-Aggregated RAN” (DA-RAN) as an alternative to the RAN and C-RAN solutions. DA-RAN adopts the concept of “disaggregation” of hardware and software components across the wireless, optical and compute/storage domains. The performance of the proposed approach is evaluated through a service provisioning...
Wavelength selective switches (WSS) and wavelength blockers (WB) are crucial elements in reconfigurable optical add-drop multiplexers and cross-connect nodes. For the "continuous spectrum" WB/WSS (CS-WB/WSS), the overall filtering passband of the WSS device can be adjusted in a quasi-continuous way by grouping two or more adjacent pixels offering enhanced switching flexibility at arbitrary...
