    • Handheld Variable Optical Attenuator

    The handheld variable optical attenuator provides convenient and rapid continuous variable attenuation of optical signals from 0 to 30 dB or 0 to 60 dB. It features a high attenuation precision of 0.1 dB and supports attenuation at five commonly used wavelengths. With backlight adjustment and display functions, it offers high attenuation accuracy and a universal interface design; attenuation values are shown on an LCD screen. This product is primarily used for the testing and debugging of optical fiber communication system equipment and instruments during R&D, development, and production. Typical applications include bit error rate testing, receiver sensitivity measurement, system sideband analysis, loss simulation, optical power meter calibration, and verification.

    Product features：Multi‑wavelength selection；Selectable optical attenuation range；Attenuation resolution up to 0.1 dB；Auto‑power‑off function; optional backlight on/off；Large‑capacity lithium battery with up to 48 hours of continuous operation

    Part Number：MP-VOA-1550-A-FC/UPC

    Application area：R&D testing of optical communication equipment | Production inspection of optical modules | Receiver sensitivity testing | Verification and debugging of optical communication instruments
