400G PAM4 QSFP-DD 至 4×100G 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 4×100G QSFP56 直連銅纜 (DAC) 是一種分支銅互連線纜，專為超大規模資料中心、HPC 叢集和企業網路中的 400G 至 4×100G 乙太網路應用而設計。
一端有一個 QSFP-DD 連接器，另一端有四個 QSFP56 連接器，可實現無縫的 400G 到 100G 分支連接，具有超低延遲和成本效率。
DAC 採用雙芯銅導體和 PVC 保護套製成，確保卓越的 EMI 抗擾度、耐用性和穩定性。被動版本支援長達 3 公尺（10 英尺）的線纜長度，且功耗極低；主動版本則可延長至 5 公尺（16 英尺），每端功耗不超過 4 瓦。
相容品牌
NS 400G QSFP-DD 至 4×100G QSFP56 DAC 可與思科、華為、瞻博網路、Arista、戴爾和 Nvidia 的裝置無縫合作。
