MEMS VOA 1310nm/1550nm fiber Variable Optical Attenuator

MEMS (micro electro-mechanical) VOA (Variable Optical Attenuator) optic fiber attenuator The MEMS Variable Optical Attenuator is based on the Micro-Electro-Mechanical System technology. These MM series attenuators can be used to achieve the remote control of the power in the networks by a MEMS chip with a movable mirror on the silicon. The mirror attenuates the laser light power by coupling the input beam onto the output fiber. The applied voltage to the device controls the mirror tilt angle, thus the desired attenuation amount. These best-in-class MEMS VOAs attenuators are available in either normally-open or normally-closed configurations and with an integrated tap option. They are driven by applying an electrical voltage.
