400G OSFP 至 OSFP 直連銅纜 (DAC)，PVC，被動，最長 3 公尺（10 英尺）
概述
NS 400G OSFP 至 OSFP 直連銅纜 (DAC) 是一款經濟高效、超低延遲的互連解決方案，適用於超大規模資料中心、雲端環境和 HPC 叢集中的 400 千兆乙太網路短距離應用。此 DAC 兩端皆整合 OSFP 連接器，無需單獨的光收發器和跳線，即可提供即插即用的效能。
被動 DAC 採用雙芯銅導體和耐用的 PVC 護套，支援長達 3 公尺（10 英尺）的線纜長度，且幾乎不耗電。對於擴展部署，有源銅纜 DAC 的線纜長度可達 5 公尺（16 英尺），每端功耗不超過 4 瓦，確保高效可靠。它具有卓越的 EMI 抗擾度、強大的訊號完整性和始終如一的低延遲。
