Highlights

The N4917B software provides an automated, standard-compliant stressed receiver sensitivity test according to 100GBASE LR4, ER4, SR4 and CLR4, CWDM4 and 4WDM specifications. To do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source must operate together to achieve a compliant, repeatable optical stressed eye. This stressed eye is then fed to the receiver under test, where bit error ratio is measured under the stress conditions as defined in the standard.

Automating the time-consuming calibration of the optical stressed eye results in time savings of more than a factor of 10 compared to the manual setup.

Turn-key software with test automation controls the whole setup, which limits the time-consuming development of individual test software.
