400G PAM4 QSFP-DD 至 2×200G QSFP56 直連銅纜 (DAC)，PVC，無源，最長 3 公尺（10 英尺）
概述
NS 400G PAM4 QSFP-DD 至 2×200G QSFP56 直連銅纜 (DAC) 是一種分支銅互連線，專為大型資料中心、雲端基礎設施和 HPC 環境中的 400G 至 2×200G 乙太網路連接而設計。
它採用雙軸銅纜和PVC護套，提供400 Gbps聚合頻寬，並透過8×50 Gbps PAM4通道分成兩個200G通道。被動版本支援長達3公尺（10英尺）的傳輸距離，且功耗幾乎為零，是短距離機架內部署的理想選擇。
為了實現更遠的傳輸距離，主動式 DAC 可支援長達 5 公尺（16 英尺）的傳輸距離，同時每端功耗不超過 4 瓦。其低延遲、強大的 EMI 抗擾度以及優於光纖解決方案的成本優勢，使其成為高密度互連應用的理想選擇。
相容品牌
NS 400G QSFP-DD 至 2×200G QSFP56 DAC 經過驗證，可與 Juniper、Arista 和 Dell 的交換器和伺服器無縫協作。
