Fiber optic connectors provide a low loss means of connecting optical circuits. Low loss is achieved by minimizing the lateral offset between optical fibers and by maintaining physical contact between the optical fibers. Physical contact can be achieved when the ferrules containing the optical fibers have a convex spherical polish on the endface. By having the apex of the spherical polish coincide with the center of the ferrule containing the optical fiber, the fibers have a high probability of achieving physical contact when mated together.
