Intelligent optical transmitter module

摘要

The present invention is an intelligent optical transmitter module that is used to produce optical test signals. The optical transmitter module contains a solid state laser and a microprocessor. The solid state laser produces the test signals which are used to test optical fibers in an optical fiber network. The laser is both monitored by and controlled by the microprocessor. In one embodiment, backface monitoring and optical output coupling power monitoring (using an optical tap) are accomplished within the module in order to more accurately reflect the state of the laser. The microprocessor reads data regarding the performance of the solid state laser which may be output to another control device. The control device utilizes the data from the microprocessor in the analysis of fiber optic loop conditions as well as the laser itself. The microprocessor enables the output levels of the solid state laser to be adjustable by way of a digital to analog converter. The test signal which is output from the module may additionally be pulsed or continuous. <IMAGE>
