Micro-processor Compensated Variable Optical Attenuator, MEMS Type

This product is an independent control module for MEMS VOA, and suitable for the situation where optical path is controlled by programmable attenuator. Using this controller, one is easy to realize accurate attenuation controlling with large range for the MEMS device. The controller contains the following characters:

(1) Easy to be integrated in quantum products.The MCVOA module attenuates the signal to the target scale (within the error range) under the commanding voltage.

(2) The error parameter fitting of MEMS VOA is independent, and accomplished with the corresponding UI software before delivering.

(3) The fitting data, which is stored in the module, keeps even when the power is off.

KEY FEATURES

Optical on/off state mode MEMS VOA.
Downloads attenuation value through serial port.
Serial line interface reads MEMS VOA temperature information.
MCU FLASH stores MEMS VOA attenuated fitting calibrating information, and the information would not be lost when power is off.
Single module supports up to 4 channels.
Supports multiple modules communication interface concatenation, and any extended channels are controlled by single interface
