We produce electrical and manual fiber optic variable attenuators for a broad application scenarios in volume, leading the market in performance and value. Perfected over 20 years, we offer the lowest loss, the highest attenuation, the fastest, the smallest, and the most reliable fiber attenuators in the industry. Our thermal actuation MEMS VOAs have the smallest size, the highest attenuation level, and ultra-high reliability. Our Fiber-Fiber™ MEMS series VOAs offer unique performances of near-lossless, ultra-broadband, and all-type fiber compatibility. Our high-precision VOAs have a built-in position sensor achieving high stability/repeatability as well as linearity. For high-speed operation, our solid-state NanoSpeed™ VOAs set an industry-standard in low loss and fast rise/fall, as well as high power handling. The table below guides fiber VOA selection according to your key requirement. All VOAs can be delivered in a turn-key net-ready box. Moreover, we provide custom solutions with in-house micro-assembly and MEMS wafer fabrication.
