Polarization Maintaining 1550nm Manual Variable Optical Attenuator
Description:
A Polarization-Maintaining (PM) Manual Variable Optical Attenuator is a precision optical device engineered to reduce and finely control optical power levels in polarization‑maintaining fiber systems. It allows users to manually adjust attenuation to achieve the desired output power while preserving the input polarization state. This makes it essential for applications where both power stability and polarization integrity are critical. New York
