Abstract
A test instrument is operable to test optical components of a fiber optic network. The test instrument includes a laser having a back-facet monitor. The test instrument measures a performance parameter of an optical component being tested based on optical power of the laser measured by the back-facet monitor. The performance parameter is determined based on optical power measurements that account for drift of the laser.
