200G PAM4 QSFP56 至 4×50G SFP56 直連銅纜 (DAC)，PVC，被動，最長 3 公尺（10 英尺）
概述
NS 200G PAM4 QSFP56 轉 4×50G SFP56 直連銅纜 (DAC) 是一款適用於超大規模資料中心、HPC 叢集和雲端環境中 200G 轉 4×50G 乙太網路連接的分支銅纜解決方案。它一端整合一個 QSFP56 連接器，另一端整合四個 SFP56 連接器，可實現 200G 轉 50G 的無縫分支連接。
這款 DAC 採用雙芯銅纜和 PVC 護套，與光纖收發器相比，具有超低延遲、可靠的訊號完整性，並顯著節省成本。被動版本支援長達 3 公尺（10 英尺）的傳輸長度，且功耗極低。對於更長距離的需求，主動銅纜版本可支援長達 5 公尺（16 英尺）的傳輸長度，功耗不超過 2 瓦。
