Fiber arrays are characterized by several key parameters, including the number and type of fibers, their spacing, and the lattice type used in two-dimensional arrays. 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. lity of polish surface. Linear, Circular, rectangular, hexagonal,. All listed parameters are typical values specified at room temperature. Additional factors include the core diameter, numerical aperture, polarization handling, end face angle, and the use of end caps or. The key parameters of the fiber array are as follows 2. What is the fiber array made of? Ⅰ. UHNA & PM fiber which is precisely oriented with high PER.
