FVA-60DVariable Optical Attenuator Product Overview
The FVA-60D handheld optical attenuator enables continuous variable attenuation of optical signals. As this attenuator is primarily designed for online testing of laser systems, it is suitable for applications in digital hierarchies (PDH, SDH) that include communication equipment, as well as systems using analog modulation (CATV).

FVA-60DVariable Optical Attenuator Application Scope
Telecommunication engineering maintenance
CATV engineering and maintenance
Integrated wiring systems
Optical device production and research
Optical communication teaching and experimentation
Other fiber optic engineering

FVA-60DVariable Optical Attenuator Product Features
Rotary dial step attenuation: step increment of 0.05dB
Capable of displaying relative or absolute attenuation values
Optional 10-minute automatic shutdown function after inactivity
After shutdown, the system remembers the attenuation and step values before shutdown; upon restart, it restores to the pre-shutdown state
