Our high-precision fiber arrays are engineered to meet rigorous technical specifications, enabling customers to define critical parameters such as channel count, fiber spacing, fiber types, face grinding angles, and overall dimensions.
The manufacturing process is optimized to achieve minimal placement errors, with typical core offsets as low as 0.5 µm. The fiber array can be populated with UHNA, PM, and multicore fibers, and optional reflective or anti-reflective coatings can be applied to further enhance the performance of the fiber array endface.
For extreme applications, we offer a specialized variant engineered to withstand cryogenic temperatures and ultra-high vacuum (UHV) conditions. Additionally, our fiber arrays can be integrated into metal housings produced in SQS on CNC machining centers for improved handling and durability. With a comprehensive range of connector interfaces—including MTP, MT, MMC, TMT, FC, LC, SC, and E2000—and manufactured from materials such as borosilicate glass, fused silica, silicon, and metal, our arrays are optimized for high-performance applications in the most challenging environments.
