Which fiber array substrate is the best
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.
