Companies such as Google, Amazon, Microsoft and Facebook started their migration toward 100G in 2015 – and smaller enterprise data centers are now in line to follow suit. Many of these new 100G deployments adopt a singlemode fiber solution for longer reach that best suits their hyperscale data center architectures.
When comparing 40G vs. 100G optical transceivers currently available in the market, both have been developed and cost optimized for their designated reach and applications.

While weighing 40G vs. 100G Ethernet, and deciding which migration path makes more sense for your organization, here are some facts you should know:

When considering system upgrades from 10G, it’s essential to understand that 40G will also be needed to support the legacy installed base with 10G ports; 40G/100G switch port configurability will certainly accelerate 100G adoption in the enterprise market.
In 2017, 100G Ethernet is already ubiquitous – it will be mainstream, not just in hyperscale cloud data centers. Next-wave 200G/400G Ethernet will soon hit the market; standards bodies have already initiated a study group for 800G and 1.6T Ethernet to support bandwidth requirements beyond 2020.
