Navigating the Shift to 800G: Dispelling Myths and Preparing for the Transition
The need for higher speed – 800G provides faster speeds, new challenges, and solutions.
By failing to prepare, you are preparing to fail.
Transitioning to 800G networking is filled with unique challenges and misconceptions. Being proactive can make the journey smoother and ensure your infrastructure is ready for the future.
Widespread Misconceptions About 800G
“400G Adoption Is Limited—800G Is Still Far Off”
Despite slow rollout and adoption of 400G optics, surging demand for data—driven by remote work and streaming—means core networks are already under pressure. Service providers, data centers, and enterprises are being forced to expand core infrastructure now to keep up with increasing demand. Many industry experts believe that the current 400G capacity may not be sufficient even for moderate growth in the coming year or two.
“My Equipment Manufacturer Will Be Ready for 800G Before I Need It”
Major industry forces suggest otherwise:
- Supply Chain and Chip Shortages: These factors continue to hamper the ability of network equipment manufacturers (NEMs) to deliver products and develop new systems in a timely manner.
- Complex Standards Environment: The accelerating pace of change in standards—like ongoing updates to the Common Management Interface Specification (CMIS)—creates additional hurdles for NEMs. Platform compatibility now varies by software version (e.g., CMIS 3.0, 4.0, 5.0), compounding integration and deployment delays.
“My Current Fiber Infrastructure Will Support 800G”
There are still technical barriers. Key industry standards—such as those for 850nm single lambda 100G over multimode fibre—have not yet been finalised by standards bodies, including the Ethernet Alliance. As a result, many organisations will need to invest in new multimode fibre optic infrastructure to support the requirements of 800G deployments.
Preparing Your Network for 800G
Proactive planning is crucial. Industry leaders are launching new solutions such as the OSFP 2x400G and QSFP-DD 2x400G transceivers to bridge the gap ahead of widespread 800G equipment availability. These transceivers can help organisations get started with next-generation networking even before every piece of their infrastructure is fully upgraded.
Investments in testing tools and equipment ensure robust support and quality as networks transition to higher speeds. By anticipating challenges and acting early, organisations can confidently smooth their path toward 800G readiness.
