N4917A Optical Receiver Stress Test Set - selected 2007 by the readers of Photonics Tech Briefs as Readers' Choice Product of the Year!

Optical receiver stress testing is one of the key challenges during the design and test phase of multi-gigabit transceivers and ROSAs. Many different flavors of data rates, distances, fibers have to be verified. Each requires a different test set up to create the so-called stressed eye defined in each standard. Engineers had to select, calibrate and operate the test equipment along with the filters and cables from different vendors. Correct interpretation of the standard requires in-depth insight of experienced engineers. All this led to hard-to-reproduce and hard-to-compare test results between test labs and between suppliers and vendors.
The figure below describes a stressed eye example required for 10 Gb Ethernet receiver testing:

The Keysight N4917A is a complete optical receiver stress test set that provides repeatable and calibrated conformance and characterization testing of optical receivers. Design and test engineers can now accurately test receive optical sub assemblies (ROSAs) and transceiver modules operating up to 14.2 Gb/s.
