Customized Single-Channel Micro MEMS Variable Optical 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.
FiberZON offers standard, mini and micro MEMS VOAs in a fast, low cost miniature package. These best-in-class 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.

WDM network
An eight channel wavelength multiplexed signal from a trunk line is demultiplexed into individual signals. The signals are of different intensities, and have to be balanced to avoid saturating any of the receivers. To do so, each channel is sent through a corresponding port on an eight channel MEMS VOA.
The signal strength through the attenuator outputs is monitored by a control circuit. If the output signal on one channel gets too high or too low, the corresponding attenuator is adjusted to bring the light level to the correct range. The complete module is very compact.
