Tips for accurate characterization of 28 Gb/s designs

The worldwide demand for data capacity in networks significantly increases every year, driven by services like cloud computing and Video on Demand. As installed networks approach their capacity, operators need to either add physical capacity, which is very expensive, or transfer more data through the existing networks. These factors drive the need for much higher data rates, and the medium and long haul transmission is handled by fiber optic networks. Data is initially and finally handled within electrical circuits, and is limited to relatively short distances primarily because of the loss in electrical channels. Within a few short years, the challenges of developing solutions that handle 10 Gb/s have faded and have been replaced with new challenges at rates of 14 Gb/s to 120 Gb/s, resulting in a proliferation of multichannel standards and applications.

Agilent continues to anticipate and provide test solutions as designers move through early development and validation cycles. This application note focuses on test solutions for electrical transmitters operating from 10 Gb/s to 28 Gb/s and beyond, and covers the commonly required test parameters and techniques.
