Polarization Maintaining Manual Variable Optical Attenuator
The PM Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading element can be integrated and adjusted to get any attenuation value in a range. MVOA features low insertion loss, good resolution, high stability and good reliability. The Manual Variable Optical Attenuator applies for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control, etc.
