摘要

在這篇論文裡我們提出使用平行運作的可調變光纖延遲線來模擬最大延遲d的彈性延遲線。我們證明，若要利用平行運作的可調變光纖延遲線來完美的模擬彈性延遲，只需要floor((2d+1)/3)條可調變光纖延遲線。我們也證明，當延遲d很大時，模擬彈性延遲平均使用到的忙碌的可調變光纖延遲線大約需要(1-2e^(-1))d條。

In this paper we propose to construct a flexible delay line with maximum delay d by parallel variable optical delay lines. We show that to exactly emulate a flexible delay line, one needs floor((2d+1)/3) variable optical delay lines. We also show that the average number of busy variable optical delay lines to approximate a flexible delay line is roughly (1-2e^(-1))d for large d.
