High-speed digital: 112 is the new 56 | EDN


EDN magazine reports that at DesignCon 2018, 112 Gbps was all over the conference and exhibit hall. Even just a year ago, engineers were still talking more about 56 Gbps speeds than 112. This year, all agree that 56 Gbps speeds have been achieved. It’s time to move on.

OIF-CEI 4.0, which included clauses for CEI-56G interfaces was approved on December 29, 2017. With that done, OIF is looking toward CEI-112G.

SFP-DD modules will support CEI-112G-VSR and will use PAM4 with forward error correction (FEC).
