SC369 - Test and Measurement for Metro and Long-haul Communications

Sunday, 19 March
13:30 - 17:30

Short Course Level: Advanced Beginner


Bernd Nebendahl, Michael Koenigsmann; Keysight , Germany

Short Course Description:

This course will explain how components and subsystems for dense wavelength division multiplexed (DWDM) systems and coherent transmission systems like optical filters, wavelength selective switches, fiber amplifiers, coherent transmitters and receivers are characterized.

There will be a focus on physical layer parameters like loss and polarization dependent loss over wavelength for passive DWDM components, dispersion, polarization mode dispersion and noise figure for amplified fiber links and for parameters describing the quality of complexly modulated signals like error vector magnitude, constellation impairments and their relationship to system performance parameters like bit error ratio, signal-to-noise ratio and quality factor.

The setups and instruments will be introduced and the operation and the performance parameters of fiber optic instruments like tunable laser sources, optical power meters, polarization controllers, optical spectrum analyzers, optical noise analyzers, optical modulation analyzers and optical modulation generators will be explained together with their influence on the measurement uncertainty of individual parameters.

By understanding the concepts engineers and decision makers will get a profound knowledge base to decide for the best test strategy for their characterization applications.

Short Course Benefits:

Attendees of this course will be able to:

  • Describe a setup to measure wavelength and polarization dependent properties of DWDM components.

  • Determine the required performance of test & measurement equipment to test optical components.

  • Measure performance parameters of optical amplifiers and fiber links.

  • Compare the quality of various transmitters through the use of EVM  measurements.

  • Relate details of constellation diagrams to specific device and/or measurement system impairments.

  • Identify the root causes of measurement degradation and uncertainty.

  • Define test strategies to validate the accuracy of test results.

Short Course Audience:

This short course is intended for engineers who start to work or already have experience in manufacturing and development of metro and long-haul communication equipment and components. Attendees should be aware of basic concepts of optical transmission and polarization of light. Research and manufacturing managers as well as technical buyers will get a profound background in order to make optimal decision for their test and measurement needs. Students will extend their knowledge in optimal test concepts for fiber optical testing.
