Variable Optical Attenuators

MEMS Broadband Optical Attenuator – Fiber-Fiber™

The Fiber-Fiber™ series VOA is based on fiber-to-fiber direct coupling with a micro-electro-mechanical (MEMS) shutter in between. It eliminates the need for lens and optical coating, featuring low loss, ultra-broadband without altering fiber transmission character, high power, compact size, and easy drive. The current MEMS chips accommodate fiber with 3 to 105 mm core diameters. VOAs with fiber of larger diameters can be made with special chip fabrication run with an NRE charge. The Fiber-Fiber™ series VOA is compliant with the Telcordia 1209 and 1221 reliability standards. The VOA is driven by directly applying a low electrical voltage. The VOA is electrically a resistor load, has no polarity, and is electrostatically insensitive.
