The substrate material affects the optical properties of the fiber array, and a material with a low coefficient of expansion is required to ensure a stress-free fiber array, high reliability, and no fiber migration at high temperatures. A fiber array, frequently called a Fiber Array Unit (FAU), is a rigid assembly containing multiple optical fibers held in a strict geometric pattern with high positional accuracy. With customizable V-groove chips and covers, and Corning's capability of developing and making specialty fibers, our FAU products can meet a wide variety of customer requirements on the inter-fiber core pitch and its precision, channel number, fib r type, and. Optical fiber array units (FAU) are essential devices for high-precision connection of optical waveguide elements and optical fibers in coherent optical fiber systems, co-packaged optics and other fiber systems and platforms. Comprising a V-groove base plate, cover plate, optical fibers, and adhesive, its core advantages lie in high-precision fiber alignment and low-loss.
