200G PAM4 QSFP56 至 QSFP56 直連銅纜 (DAC)，無源，最長 3 公尺（10 英尺）
概述
NS 200G PAM4 QSFP56 至 QSFP56 直連銅纜 (DAC) 是一種高效能、短距離互連，專為超大規模資料中心和 HPC 叢集中的 200 千兆乙太網路應用而設計。
它採用雙軸銅纜和工廠端接的 QSFP56 連接器構建，可在 4×50 Gbps PAM4 通道上提供 200 Gbps 頻寬，提供超低延遲和經濟高效的性能。
被動 DAC 支援長達 3 公尺（10 英尺）的傳輸距離，且功耗幾乎為零。對於需要更長距離的部署，主動式 DAC 選項可將距離延長至 5 公尺（16 英尺），同時功耗低於 2 瓦。這使其成為成本和效率至關重要的架頂式 (ToR) 和列中式 (MoR) 連接的理想選擇。
相容品牌
NS 200G QSFP56 DAC 已與思科、華為、瞻博網路、Arista、戴爾和 Nvidia 的設備進行互通性測試。
