In this deck from the 2019 OpenFabrics Workshop in Austin, Ariel Almog from Mellanox presents: To HDR and Beyond.
"Recently, deployment of 50 Gbps per lane (HDR) speed started and 100 Gbps per lane (EDR) which is a future technology is around the corner. These technologies exposing various new physical interfaces for copper and optical interfaces and type of transceiver like SFP-DD. Supporting these speeds also toughen the task to get low BER (Bit Error Rate) through FEC (Forward Error Correction) algorithm. The high bandwidth might cause the NIC PCIe interface to become a bottle neck as PCIe gen3 can handle up to single 100 Gbps interface over 16 lanes and PCIe gen4 can handle up to single 200 Gbps interface over 16 lanes. In addition, since the host might have dual CPU sockets, Socket direct technology, provides direct PCIe access to dual CPU sockets, eliminates the need for network traffic to go over the inter-process bus and allows better utilization of PCIe, thus optimizing overall system performance."

The document also covers IP traffic over WDM networks, MPLS approaches for IP over WDM including GMPLS control planes, and optical internetworking and signaling across network boundaries.
The document discusses LTE backhaul considerations for network evolution. It emphasizes that backhaul must support LTE's technical requirements while ensuring business profitability. A successful backhaul solution enables seamless evolution through flexible topology, granular QoS controls, and simple network changes. IP/MPLS is recommended to provide service and transport independence across 2G, 3G and LTE networks.
