Abstract
An arrangement for optical communication comprises an optical coupler, an opto-electronic board, and an optical fiber. The optical fiber comprises a first refraction surface, a second refraction surface, and an internal reflector. The first refraction surface has a first finite focal length. The second refraction surface has a second finite focal length. In operation, an optical signal enters the first refraction surface, couples from the first refraction surface to the second refraction surface via the internal reflector, and exits the second refraction surface, where the optical signal defines a light path. The light path optically couples the opto-electronic board to the optical fiber.
