Track: 13. Applying Test & Measurement Methodology

Audience Level: Intermediate

Session Type: Technical Session

Description: The paper is to provide a detailed analysis of the relationship between the return loss of the channel, its components, and the channel operating margin (COM) results supporting the introduction of effective return loss (ERL) for the IEEE 802.3cd 50 Gb/s lane standard. ERL is characterized as a figure of merit for the electromagnetic wave reflection from a device or a channel input or output It is calculated using the a method described in the draft standard. The paper will provide practical examples of implementing the ERL method for transmitters, receivers, and cable assemblies by measurements of their scattering parameters.
