FVA-40 is an advanced digital variable attenuator. It is widely used to reduce the power level of an optical signal to meet input request in various applications. The compact instrument allows the user quickly and accurately setting attenuation on four calibrated wavelengths, 1310nm, 1490nm, 1550nm and 1625nm, which are commonly used in FTTH and Fiber Monitoring. Consolidating with digital coarse and fine adjustment, it is more suitable for a laboratory, production environment and field work. With one of FibreOptica's optical power meter series products, the user can simply select a suitable output level. Not limited to specified wavelengths, this device can be used for other wavelengths within the applicable range if necessary.
