Data center operators need to evolve their networks from 100GE to 400GE to support the bandwidth and response times required by emerging technologies such as fifth-generation wireless (5G), artificial intelligence (AI), virtual reality (VR), Internet of Things (IoT), and autonomous vehicles. In less than 15 years, data center speeds have evolved from 10GE to 100GE. Data center 100GE implementations began in 2014, yet full build-outs only became cost-effective over the last couple of years thanks to the availability of more affordable optical transceiver modules. Meanwhile, research and development for 400GE transceivers is well underway and is expected to reach mature pricing within a year of introduction.

Next-generation 400GE optical transceivers need to use less power per gigabit, be less expensive per gigabit, and operate at four times the speed of 100GE transceivers. Modern hyperscale data centers house more than 50,000 fibers with an optical transceiver at each end. Transceiver designers need to find a way to simultaneously increase channel capacity, guarantee quality and interoperability, and reduce the cost of new 400GE transceivers.
