Optical Receiver Stress Test Solution
N4917B
-
The N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE-LR4, ER4 and SR4 test specification. In order 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 are required to 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.
