MEMS Variable Fibre Optical Attenuator >65dB
21 June 2021Ultra-small MEMS fibre optical attenuators up to 65dB are announced. These devices uniquely feature both excellent optical performance and ultra-high reliability, and share a compact footprint with a narrow packaging width of only 4.5mm.
MEMS Straight Fibre Optical Variable Attenuator
The MEMS Straight Series Fibre Optical Variable Attenuator uses a patented thermal activated micro-mirror, moving-in and -out optical paths, uniquely featuring large extinction ratio, high stability over wide temperature range, and very long life cycle. The thermal MEMS is insensitive to moisture and ESD without drift issues, providing a high reliability platform for over 25 years continuous operation. The MEMS Straight Series VOAs are configured in single and dual channels (activated at the same time). The VOAs are bidirectional and are Telcordia standards GR1221 qualified.
Compatible MEMS Reflective Fiber Optical Variable Attenuator
The Compatible MEMS Series Fibre Optical Variable Attenuator is constructed using a standard VOA core having a circular end shape and pins that are compatible with VOAs made by other manufactures for easy replacement. It uses a patented high reliability thermal activated micro-mirror, moving-in and -out optical paths, uniquely featuring large extinction ratio, high stability over wide temperature range, and exceptionally long life cycle. Unlike electrostatic MEMSs, the thermal MEMS has no drift issues and is insensitive to moisture, vacuum environment, and ESD, providing a high reliability platform for over 25 years continuous operation. The MEMS Straight Series VOAs are configured in single and dual channels (activated at the same time). The VOAs are bidirectional and are Telcordia standards GR1221 qualified.
Mini MEMS 24 Channel VOA Array
The etMEMSTM series VOA is based on a micro-electro-mechanical mechanism featuring compact design, simple construction, easy direct drive, and excellent optical performance. The etMEMSTM series VOA is compliant with the Telcordia 1209 and 1221 reliability standards. The VOA is driven by directly applying an electrical voltage.
