Fiber Array (FA) is an array formed by arranging a bundle of optical fibers or an optical fiber ribbon at specified intervals on a V-groove substrate.
With the rapid growth of data traffic and the demand for large-scale data center construction, data centers are rapidly developing towards ultra-high speed, integration, and low cost. Optical transceiver modules adopt small volume, high integration solutions, and the demand for parallel high-speed optical components is also growing rapidly.
FA is a component that arranges multiple optical fibers in a two-dimensional or three-dimensional structure. They are commonly used in optical communication and sensing applications, enabling the distribution, combination, or connection of multiple optical signals. FA typically include multiple fiber sockets, each containing one optical fiber, and these sockets can be arranged at certain intervals. FA can be used to build optical interconnection systems, optical switches, optical couplers, and various optical sensor devices.
The design and manufacturing process of FA need to consider factors such as the spacing between fibers, alignment accuracy, and connection stability. During the manufacturing process, micro-machining and precision assembly technologies are often employed to ensure accurate alignment and stable connection of the optical fibers. The performance and quality of FA directly affect the performance and reliability of the entire optical system.
FA are most commonly used in the packaging of Planar Lightwave Circuit (PLC) and Arrayed Waveguide Grating (AWG). With the rapid advancement of 400G and 800G high-speed transmission, the demand for FA in data centers and 5G commercial applications is growing rapidly. Besides the field of optical communication, FA are also widely used in MEMS systems, sensors, silicon photonics, and other areas.
