MEMS VOA optic fiber attenuator  Variable Optical Attenuator micro electro-mechanical optic fiber attenuator

 

 

 

1.  Description

PG designs and manufactures innovative, photonic integrated circuit (PIC) based MEMS (micro electro-mechanical systems) Variable Optical Attenuator for next generation, dynamically configurable optical networks.

PG’ MEMS products base on electrostatic MEMS technology, The reflective mirror MEMS technology enables the creation of products with high attenuation levels and can be configured as bright or dark devices. When combined with the

 

PG advanced packaging and manufacturing capabilities, this results in a new category of MEMS components that are designed to exceed specifications for performance, compactness, manufacturability and reliability.
