Optical Variable Attenuators

Photonwares offers the largest selection of variable optical attenuators (VOAs) with multiple technologies for wide application scenarios. VOAs are commonly used along with a tap monitor to control light intensity. MEMS VOAs is often used for this application. Our MEMS VOAs offer the smallest size and integrated monitor. For some applications, no feedback control is preferred, our mini-motor VOAs provide set and forget latching function. 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. Our Fiber-Fiber™ offers unique performances of near-lossless with little back-reflection, ultra-broadband, and all type fiber compatibility.  We are a leading volume manufacturer of fiber optical attenuators providing industrial leading performances and values. Our VOAs are all Telcordia standard GR1221 qualified. Photonwares provides customized designs as well as module integration with full function and control.
