Variable Optical Attenuator

DESCRIPTION

- This product using the 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.

FEATURES

- Low insertion loss

- Low polarization dependent loss

- Miniature design

- Low power consumption

- High shock & vibration immunity

- Telcordia 1209 & 1221 compliant

APPLICATIONS

- Channel on/off switch

- Channel equalization

- Receiver protection

- Power equalization in OADM/ROADM

- Power equalization in VMUX

- EDFA GAIN-TILT control
