The BVA3400 series benchtop variable optical attenuator is a high precision mechnical attenuator, which can provide 0 to 65dB large attenuation range. It can calibrate Max 10 wavelength at one time and compatible with both SM and MM signal. With the interchangeable FC/SC/ST connector, BVA3400 series benchtop variable optical attenuator can accommodate with FC/SC/ST connector. 

There is special “Shutter” design inside the VOA, which can completely “shut off” optical signal, avoid the repeatedly pulling in or out, greatly improve the working efficiency and protect the connector port. The attenuation loss is automatically calculated via “REF” function and avoids the complicated calculation. The remote-control function can be realized via RS232 port.
