產品介紹
產品定位與應用Keysight / Agilent / HP HP81560A Agilent / Keysight 81560A Optical Attenuator Module 光衰減器模組
Optical Attenuator Module
AI 伺服器高速光互連測試 屬於頻譜與訊號分析設備，適合用於載波、雜訊、諧波、雜散、調變品質、通訊訊號與 EMI 預掃測試等情境。
實際量測範圍與選配需依機身配置、附件與校正狀態確認。
選型時建議同步確認頻率範圍、分析頻寬、相位雜訊、DANL、前置放大器、追蹤產生器與量測應用軟體，避免後續因選配、治具或校正條件不符而影響測試進度。
弘燁科技可依目前庫存、附件組合、校正需求與交期，協助比對同級替代型號並整理詢價所需資訊。

原廠英文說明
The Agilent/HP 81560A is a variable optical attenuator plug-in module (single slot) for Agilent's Lightwave Multichannel Platform 8163, 8164 and 8166 series. Small and cost effective, this HP81560A module offers high resolution (.001dB) for single wavelength applications. Using 9/125 um single mode optical fibers (SMF28), Agilent 81560A features an integrated shutter which can be used for protection purposes or to simulate channel drops if available.In addition, by entering the operating wavelength, the instrument automatically applies the appropriate corrections. Typical return loss is 45dB; Straight fiber connector.
