September 14, 2018 | 100G per Lambda Optics Paving Fast Path to 25Tbps Switches with 100G Electrical I/O

By Jeff Twombly, VP of Marketing and Business Development at Credo, @twoms63.

With increased demand for global network bandwidth, the hyper-scale cloud providers are in a position to consume the next generation of higher capacity, 100G SerDes enabled switches as soon as they can get their hands on them.  Cloud providers are already operating at extremely high rates of utilization and would welcome a higher performance, intelligent and more efficient intrastructure boost.  The key technology building blocks are in place to prototype 25.6Tbps switch based networks in 2H2019 and ramp in 2020.  This is a year or two ahead of popular thought.


 August 27 | 25/100 Gbps Record Port Setting Shipments in 2Q18, 56Gbps SerDes ramping, path to 112Gbps SerDes in sight

2Q18 saw record setting shipments for both 25 Gbps and 100 Gbps port shipments.  In the Data Center Ethernet Switch market, 100 Gbps is now the largest contributor to revenue, surpassing 10 Gbps.  This is an important milestone as 40 Gbps was never able to exceed 10 Gbps, nor ever able to break the $1B a quarter milestone.  This ends an almost ten year run for 10 Gbps being the dominant technology in the data center.


July 18, 2018 | 100G Workshop in Santa Fe Pushing 400/800 Gbps Ports Ahead

The speed at which networking is evolving in the data center is accelerating.  Four year cycles that we saw in the transition from 10 Gbps to 25 Gbps are shrinking and the 100 Gbps to 400 Gbps port cycle will occur even faster.  The market will move from 56 Gbps SERDES to 112 Gbps SERDES in less than two years. There are a number of reasons why we are in the midst of more rapid technology transitions, but it can be summed up by more intelligent and efficient infrastructure.  The introduction of the Smart NIC, and years of data are allowing the cloud providers to run at extremely high rates of utilization which is causing network bandwidth and topologies to evolve.


April 26, 2018 | 112 Gbps SERDES Based Products Around the Corner

By Alan Weckel, @AlanWeckel, Founder and Technology Analyst at @650Group.

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.
