Optical Stress Test Typical Setup For 100GBASE-LR4/ER4
and SR4
The N4917B optical receiver stress test solution consists of a BERT plus a sinewave generator for
electrical signal and stress generation; an electro-optical converter that modulates the optical
signal and a digital sampling oscilloscope/CDR which is required for calibration of the stressed
eye. Example setups for LR4/ER4 and SR4 are shown in the figures below. See the configuration
guide for a full list of supported instruments.
