Highlights

Capabilities

  • IEEE 802.3bs standard compliant stressed optical receiver characterization for 400GBASE-LR8 / -FR8 / -DR4, 400G-FR4 MSA, and 200GBASE-LR4 / -FR4 / -DR4 modules
  • One vendor turnkey solution automates all required instruments in the solution
  • Repeatable and stable calibration of optical stressed PAM4 signal
  • Adjustable target values for outer extinction ratio (OER), transmission and dispersion eye closure (TDECQ), and optical modulation amplitude (OMA)

Functionality

  • Unified instrument control and setting with the N4917BSCB software
  • Automated stress signal calibration, receiver sensitivity, and jitter tolerance measurements
  • Customized device testing and reporting via DUT control and scripting interface
  • Adjustable stress mix for user-defined calibration
  • Flexible calibration based on customer-defined parameter settings

The Keysight N4917BSCB optical receiver test solution is a complete, automated, and repeatable solution for optical receiver stress test. It provides repeatable calibration of the optical stressed eye, saving hours of calibration time compared to manual calibration according to IEEE 802.3bs clause 121, 122, and 124. The N4917BSCB solution software enables control and setting of all required instruments for calibration, receiver sensitivity, and jitter tolerance tests.

The optical receiver stress test solution leverages the M8040A 64 Gbaud high-performance BERT and includes an arbitrary waveform generator, an optical reference transmitter, a DCA series digital sampling oscilloscope, a tunable laser source, and an optical attenuator. The solution supports alternative setup configurations, and you can use the hardware for other kinds of device-compliance tests such as for optical transmitters and chip-to-module interfaces.
