We produce fiber optic switches for all application scenarios in volume, leading the market in performance and cost. Perfected over 20 years, we offer the lowest loss, the fastest, the smallest, and the most reliable switches in the industry. Our switches have some uniquely state-of-the-art attributes: nearly lossless, 300-2000nm ultra-broadband, single-mode core as small as 3 μm and multimode core as large as 1mm with little distortion/loss, 10ns fast switching, 20W high power handling, over 26dB polarization extinction, vibration insensitive, vacuum compatible. Moreover, we provide custom solutions with in-house micro-assembly and MEMS wafer fabrication. The table below guides optic switch selection according to the main application requirement. All switches can be delivered in PM fibers and high-power versions with cost-effective driving electronics and user-friendly GUI control software, as well as in a turn-key net-ready box. Photonwares also design/produce integrated modules/systems with customized functions.
