A WDM measuremement system (1) includes a tunable laser (10) for providing light to a WDM (30), a power meter module (110) for detecting optical energy from the WDM, an RL module (120) for measuring return loss of the WDM, a polarization controller (20) connected to the tunable laser for controlling a polarization state of the light from the tunable laser, and a PC device having control software. The tunable laser, the RL module, the power meter module and the polarization controller connect to the PC device using a GPIB cable.
