40G QSFP+ 至 QSFP+ 直連銅纜 (DAC)，無源，最長 7 公尺（23 英尺）
概述
NS 40G QSFP+ 轉 QSFP+ 直連銅纜 (DAC) 是一款低成本、低延遲的互連產品，專為短距離 40 Gb 乙太網路連結而設計。它採用雙軸銅纜和工廠端接的 QSFP+ 連接器，為機架內和相鄰機架部署提供了光收發器和跳線的即插即用替代方案。
被動版本支援長達 7 公尺（23 英尺）的連接長度，無需額外供電。對於更長的連接距離，主動銅纜版本可以以極低的功耗（< 1.5 瓦）擴展連接。此電纜可確保穩定的訊號完整性、一致的延遲以及出色的 EMI 抗擾度，適用於密集的資料中心環境。
相容品牌
NS 40G QSFP+ DAC 已驗證可與 Cisco、華為、Juniper、Arista、Dell、Intel、Extreme 等公司的設備一起使用。
