· Direct Setting of Output Optical Power

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 requires measurement 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 stable output signals.

· Programmable Setting
Allows pre-programming of commonly used attenuation levels for quick and efficient user application.
