Variable Attenuators
Used in In-line Power Control in Multi-channel Optically Amplified Systems, Transmitter Power Equalizationand, and Laboratory R&D, the SANWA Variable Optical Attenuators feature high resolution and convenient manual adjustment. It has low insertion loss, low wavelength-dependent loss, and low polarization-dependent loss. It is designed for pre-emphasis attenuation, detector saturation control, in-line power equalization, and amplifier power control.
Customized designs to meet specialized feature applications are also available.
Mini Manual Variable Attenuators
SANWA's Mini-type Manual Variable Optical Attenuator (MVOA) operates by manually moving a shading element into an 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. It is applied for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control.
