980nm SM MEMS VOA
       980nm SM MEMS Variable Optical Attenuator (MEMS VOA) is an optoelectronic products designed for attenuating 
the optical power, it intergrates with a MEMS chip inside to adjust the angle of the reflection prism to achive the optical
power attenuation function, it's widely used in WDM fiber system, fiber line protection and optical power monitoring field.

Notification:
1. The MEMS products are particulary sensitive of ESD (electro-static discharge), it's recommended to use grounded anti-static 
    wrist straps and grounded anti-static mats before handling the products. 
2. Make sure the driving voltage is 0V before and after operating.
3. when switching on the circuit, connect ' - ' (pin2) first, then ' + ' (pin 1) and upgrade 
    voltage slowly. when switch off the circuit, power off '+' (pin 1) first, then ' - ' (pin 2).
4. Always take anti-static measures to storage the products when not in use.
