    產品特性

    • 適用於 PAM4 模組與元件的 FEC 感知實體層測試
    • 在不對其他通道施加應力的情況下,透過單一應力通道,以 FEC 技術量測 400G 乙太網路鏈路中的訊框遺失率
    • 符合 400GAUI-8 和 400GBASE-LR8/-FR8/-SR8 介面的 IEEE 測試規格
    • 支援 PRBS 或 FEC(KP4)模式下的 26.5625 Gbaud PAM4
    • 強大的分析工具

    加速下一代資料中心 400G 裝置的部署

    Keysight N4891A 400G 前向誤差修正(FEC)感知相符性測試解決方案,具備靈活特性與完整功能 ,它可因應 400G 光收發器模組和相關主 ASIC 的測試關鍵缺口:在第一層相符性測試中監控 FEC 效能。

    此解決方案助您了解如何在 FEC 要求下,對元件與系統設計進行取捨,並預測系統在真實條件下的邊限。

    N4891A 解決方案可結合 M8040A 64 Gbaud 高效能 BERT 使用,在待測單通道內產生正確分割的 FEC 測試碼型,並可搭配 A400GE-QDD 400GE 第一層 BERT 和 KP4 FEC 多埠測試系統,為其他 7 個通道提供經正確校驗的分割 FEC 訊務流量,以便在應力條件下量測測試介面的 FLR。

    400GABASE FEC 感知解決方案可與是德科技相符性測試解決方案搭配使用(如光接收器應力測試和 IEEE 802.3bs 接收器測試先期認證應用軟體),提供快速、準確且可重複的光學與電子應力信號校驗,以滿足互通性測試需求。

    400GBASE FEC 感知接收器測試解決方案可因應下列應用需求:

    • 400G 系統與元件設計
    • 符合 IEEE 802.3bs/cd 標準的 400GE 互通性測試

    FEC 感知第一層測試原理

    FEC 碼字統計頁面 ─ 透過進階量測結果,如執行 FEC 前的 BER、訊框遺失率,完成 FEC 埠統計。
