The present invention is a module for use in an optical fiber administration system, or a dedicated system. The module contains both an optical transmitter and an optical monitor, wherein the module transmits a test signal over a fiber optic network and receives back that same signal through a different fiber in the fiber optic network. By both sending and receiving the test signal, the integrity of different paths in the optical fiber network can be determined in a space efficient manner. The module contains a microprocessor. The microprocessor reads data regarding the test signal as it is transmitted and that same test signal as it is received. This data may be read to an external shelf controller. The shelf controller utilizes the data from the microprocessor in the analysis of fiber optic loop conditions as well as the laser itself.
