Sercalo's fiber optic Variable Optical Attenuator is based on an electrostatic MEMS mirror. The normally open (bright) type or high attenuation. A voltage between 0-6.5 V on the drive pin sets the optical attenuation. When power is removed the VOA returns into its default state.

The MEMS component is hermetically sealed. The part is designed to conform to Telcordia 1221 reliability standards. No epoxy is present in the optical path. The optical collimator is assembled using laser welding techniques which results in long term stability and excellent reliability. The component withstands rugged environments. It can directly be mounted on printed circuit boards. The component is compliant to ROHS requirements 2015/863/EU.

Sercalo’s COAXIAL TYPE VOA is non latching and returns to the default position at power-off, i.e. the bright variant returns to the minimum insertion loss position, whereas the dark variant returns to the high attenuation state (I.e it is blocking the light at power off). The VOA works over the wavelength range of the fiber, but wavelength dependent loss is specified within one single band (50 nm).

The VOA is also available for specialty fiber at 650, 750, 850 and 980 µm. Also variants with Polarisation Maintaining fibers are available.
