2018 has been off to an impressive start with many 400 Gbps announcements and likely another record year for data center networking growth. With shipments of 400 Gbps starting in late 2018 and widespread adoption in 2019, it is important to start looking at what is coming next as we look into 2H19 and 2020. All current 400 Gbps announcements are based of 56 Gbps SERDES, so 8 lanes of 50 Gbps. This is an interim technology as the next important technology which has already been demonstrated electrically and optically is single lane 100 Gbps via a 112 Gbps SERDES. 400 Gbps ports ultimately come in two waves, with the second wave being the more important one for the market and being the enabler of an important building block for the market.
