“…Moreover, the switch controlling overhead should be independent of the network scale. Considering the scale of practical DCNs, which typically comprise hundreds of thousands servers, switch control mechanism needs to be performed in parallel and independently for every optical switch, not a network-wide scale schedule [123]. In addition, for the label control mechanism, the edge nodes should be time-synchronized connected to the optical switches at a very fine granularity (ideally few nanoseconds) to align the label signals and corresponding data packets [4].…”

“…circuits, such as all-digital CDR [11][12], gated VCO CDR [13], and over-sampling CDR [14][15][16], either lack practical integration in OPS transceivers or can only achieve microsecond-level data recovery [17][18]. Therefore, there is an urgent need to develop efficient nanosecond CDRs to meet the demands of nanosecond OPS networks.…”
