Description
Minimum and maximum Optical Rx Input levels are verified by looping the Optical
Tx and Rx ports through the Optical Attenuator and checking for error-free
operation with identical Tx and Rx patterns selected. The signal level to the Optical
Rx input is measured using the Power Meter and adjusted using the Optical
Attenuator for the required minimum and maximum levels.
