SKU: FFSW

The FF Series fiber optic switch delivers industry-leading performance, offering nearly lossless, continuous light transmission without perturbations. Its ultra-broadband operation is limited only by the intrinsic properties of the fiber, making it highly versatile for a wide range of applications. The switch features fast switching times (<1 ms), insensitivity to temperature and vibration, a high on/off extinction ratio, high polarization extinction ratio, and cost-effective. At the core of this innovative design is a MEMS-based auto-alignment silicon chip, which achieves direct fiber-to-fiber coupling. A tiny gap (less than 5 microns) between fibers is filled with a non-fluorescent, index-matching liquid, creating an ultra-low-loss optical path without requiring lenses or coatings—effectively eliminating surface reflection issues. This design ensures continuous, high-fidelity light transmission, making it ideal for spectroscopy, optical coherence tomography (OCT), interferometry, and other systems sensitive to optical losses and reflections. The FF platform is compatible with all fiber types that have a 125 µm outer diameter, including single-mode (SM), multimode (MM), polarization-maintaining (PM), double-cladding fibers, and bend-insensitive fibers, supporting both large and small core configurations. The switch operates via an electrical relay with a latching mechanism, maintaining the selected optical path even when power is removed. Bidirectional light paths are controlled using a 4.5V electrical pulse, with no continuous power consumption required—energy is only consumed during switching events. Two versions of MEMS chips are available: a fast-switching chip optimized for single-mode fibers and a slow-switching chip designed for polarization-maintaining fibers. The PM fiber switches maintain both polarization states consistent with the input fiber’s alignment.
