Cost and energy consumption analysis of advanced WDM-PONs

A Research Framework for the Clean-Slate Design of Next-Generation Optical Access

“…9. 6 We set the tolerance value to 10% of the sample mean of performance measure for the dedicated architecture in non-inferiority testing with the significance level (α) of 0.05. As expected, adding more transceivers greatly improves the ECR as n increases.…”

“…In fact, many NGOA network architectures have been proposed by both academia and industry and are now under extensive study (e.g., [5], [6], [7], [8]). Unfortunately, most of the existing works lack a systematic comparison of these candidate architectures under realistic operating environments; they are based on the comparison of network-level performances (e.g., packet delay and throughput), reaches, splitting ratios, and energy consumptions under static or limited statistical traffic configurations without taking into account the actual performances perceived by end-users that reflect the impact of higher-layer protocols including transmission control protocol (TCP) flow and congestion control.…”

Reliable and Cost Efficient Passive Optical Interconnects for Data Centers

“…The overall results cover the cases of 1 Gbps and 10 Gbps transmission capacity per server. Table I shows the MTBF and the cost values for the involved components [8], [13], [14], which are used to evaluate the reliability and the total cost of the proposed POI architectures. Fig.…”

Flexible TDMA/WDMA passive optical network: Energy efficient next-generation optical access solution

“…( This architecture is simple (using a legacy power-split ODN) and provides full [24]. As an AWG has a smaller insertion loss than a power splitter, this architecture has a better power budget and can support more users and a longer reach.…”
