Abstract
The loopback apparatus disclosed herein is used with an optical fiber system having an optical fiber cable. The loopback apparatus includes an optical fiber having input and output ends and an output optical fiber having input and output ends. The loopback apparatus also includes an optical system that defines an optical path and that is configured to optically couple the output end of the input optical fiber with the input end of the output optical fiber over the optical path. The loopback apparatus also includes a thin-film filter disposed in the optical path and configured to provide a select amount of attenuation for light traveling over the optical path. The loopback apparatus can be plugged into and unplugged from the optical fiber cable. Loopback methods for measuring the performance of the optical fiber system using the loopback apparatus are also disclosed.
