56G/112G Link Foundations Standards, Link Budgets & Models

This article consists of a collection of slides from the author's conference presentation. Some of the specific areas/topics discussed include: data center bandwidth needs driving demand for 56G/112G electrical and optical links: 2 key standards: OIF-CEI Et IEEE 802.3 (Ethernet) - NRZ to PAM4 transition has led to new specifications - Most 56G standards complete. Several 112G standards under development: channel operating margin (COM) is a standardized technique for link budgeting: link models enable efficient design exploration and system level optimization.
