Conventional optical attenuators only provide an attenuation level for the input optical signal and display this attenuation on the screen. However, the output optical signal level after attenuation still needs to be measured with an optical power meter. In contrast, the OVA-50 optical attenuator with direct output optical power setting function can accurately set and stably output optical signals, effectively integrating an optical attenuator and an optical power meter into one device. It also avoids the impact of input signal fluctuations, ensuring the stability of the output signal.
