Interlaken Interface Specification

Interlaken interface electrical specifications can be found in Interlaken Interoperability Recommendations.

This document focuses on Interlaken interface recommendations for typical applications up to 400 Gbps packet transfer. It also shows the connector and cable assembly channel and contributed differential insertion loss. The end to end interoperability loss budget can also be found in this document as the required specification in channel design process.
