In this White Paper, we will provide a tutorial of AN and LT for 112G SerDes based 100 Gbps, 200 Gbps, and 400 Gbps Ethernet, and guidelines for when AN and LT is needed.
Auto Negotiation (AN) and Link Training (LT) are key elements of Ethernet transmission over electrical connections and can reduce overall installation time, minimize the risk of configuration mistakes and optimize the performance. During the AN process, two connected devices exchange information about their transmission speed and FEC abilities and agree on a common set of transmission parameters. LT is then used to automatically tune the transmit equalizer settings at each device for minimum BER at the selected transmission speed.
Topics include:
- Background on 100G, 200G and 400G Ethernet using 112G SerDes
- Basics of Auto Negotiation
- Link Training
- How to use AN and LT
