Abstract
An accurate method for characterizing optical fiber using a modest enhancement to equipment that is already in place for other purposes within an optical transmission system is thereby disclosed. In particular, optical amplifier light sources already embedded in transmission equipment are used to provide accurate characterization information in addition to their conventional purpose. Therefore, the invention permits fiber characterization at little additional cost over the optical amplifier light sources already present in a system. Furthermore, the need of going out to the field, disconnecting the transmission equipment and performing the field measurements with separate test equipment is eliminated.
