Optical power attenuation and monitoring products are widely applied in fiber-optic communication networks. O-Net Tap-PD Monitor integrates power monitoring and tapping functions into compact single channel and array packages with high performance and reliability. Variable optical attenuators are generally used for power equalization in multi-channel optically amplified or configurable networks. O-Net provides both MEMS VOA and manually adjustable VOA to satisfy different customer needs for performance and cost.
