Optical Variable Attenuator
Variable Optical Attenuator, we have developed an option that integrates both a coupler and a power meter into the one-slot attenuator module. This allows users to set the output power level directly, thus improving the overall testing efficiency. By allowing users to monitor the attenuator’s output power in real time, the internal power meter can also be used to compensate for any power fluctuation generated from the source, while maintaining stable conditions at the device under test.
