400G is now supported on systems from many companies, providing an attractive alternative to using multiple 100G interfaces where higher throughput is required. 400G interfaces and optical modules have been challenging to develop, but these are rapidly becoming available from multiple suppliers. During 2018, companies will introduce second-generation 400G interfaces and optical modules, significantly increasing port density and ensuring strong market adoption by service providers and data center operators.
This is one of the many key findings in the latest Heavy Reading report, 100/400G Components Survey: 2018 Market Outlook, which is based on an exclusive worldwide survey that drew responses from over 80 professionals that represent 50 different telecom and networking equipment suppliers. The report charts the use of 100G, 400G, 800G and other interface speeds. It includes information about which interfaces are being supported, the importance of different 400G Ethernet port types, the use of PHY devices and 100-400G optical modules and the most important features when system developers select these modules. It also includes vendor rankings for PHY devices and optical modules, and valuable trend data using results from previous surveys.
