AV6381B is a small programmable optical attenuator newly launched by 41 Institute in 2008. It adopts new appearance and circuit design. It can provide 0-60dB continuous adjustable attenuation in the wide wavelength range of 1200-1650nm. It has extremely high performance. reliability and stability.

main feature:

New design, more comfortable and lighter

0 ~ 60dB attenuation range: AV6381B provides a continuously variable attenuation range of 0 ~ 60dB (excluding insertion loss), and provides a shutter function to meet the needs of users to cut off the optical path.

1200~1650nm wide wavelength range: AV6381B can attenuate in the 1200~1650nm wide wavelength range, and the attenuation data of each wavelength point can be automatically corrected through specific correction data to ensure the accuracy of the attenuation data.

GPIB interface: AV6381B provides a GPIB interface, which can be easily connected to a computer. With other test instruments, users can form the required automatic test system by themselves.

AV6381B programmable optical attenuator is suitable for testing and debugging of optical fiber communication systems, equipment and instruments in the process of research, development and production.
