Our company according to the developing optical communications designs the FVA digital optical attenuator. This handheld variable attenuator enables consistent operation in manual testing situations, such as BER testing and acceptance, power meter calibration and certification, optical margin analysis loss simulation, as well as field, manufacturing and R&D applications.
| | Features: | - ±0.1dB attenuation Resolution
