800G optical transport

800G adoption is ramping up

Coherent technology innovation has made it possible to transport 800Gbit/s per DWDM channel. This helps network operators to increase the capacity of their transport networks and meet ever-increasing traffic demands. However, with 95GBd solutions, the use of 800Gbit/s channels has been limited to short routes. On long routes, network operators have had to choose between using optical regeneration or decreasing channel speeds. Since optical regeneration has a significant impact on cost, reducing speed has usually been the preferred option. But things have changed. Our 800Gbit/s FSP 3000 TeraFlex™ CoreChannel™ with 140Gbd technology offers fine granular modulation combined with a wider range of symbol (or baud) rate options. This gives operators a choice. They can choose an ultra-high baud rate for 800Gbit/s for long-haul distances. Or they can minimize spectrum use by harnessing lower symbol rates over shorter spans. This ensures ultimate efficiency and highest performance from metro to long-haul networks.

Market’s longest 800G reach

With its 140GBd sub-carrier technology, our FSP 3000 TeraFlex™ CoreChannel™ ensures 800Gbit/s transport with highest efficiency, highest performance and lowest cost
With the FSP 3000 TeraFlex™ CoreChannel™, users can now transport data at 400Gbit/s or 800Gbit/s over longer distances than ever before.

From metro to long-haul

Compatible with existing and new network infrastructure, our FSP 3000 TeraFlex™ CoreChannel™ sled enables customers to harness 800Gbit/s optical transport for a wide range of networks.

Optimal 800G transport performance

Our 800Gbit/s FSP 3000 CoreChannel™ sled is specifically engineered for flexibility and ultimate efficiency. Its adaptive baud rate ensures minimal spectrum usage, which is kept low when network conditions are favorable. However, the CoreChannel™ sled’s 140Gbd sub-carrier technology gives it the option to harness ultra-high baud rates and carry up to 800Gbit/s further than ever before. This provides over 50% reach improvements compared with 95GBd solutions. Operating at higher symbol rates at a given data rate permits the use of lower-order modulation formats, which strongly correlates with longer transparent reach. This avoids the need for regeneration on long-haul paths, which can otherwise add significant costs. For shorter spans, the high flexibility of the 800Gbit/s CoreChannel™ enables the symbol rate to be reduced. This facilitates the use of higher-order modulation formats, which maximize spectral efficiency.

Industry-leading SNR metrics

Long-haul transport with FSP 3000 TeraFlex™ CoreChannel™ is even more efficient and reliable thanks to its superior signal-to-noise ratio requirements and higher network performance.

Smooth migration to 400GbE

With fractional QAM, our FSP 3000 TeraFlex™ CoreChannel™ sled supports multiple modulation formats and baud rates without rigid performance steps. This outstanding flexibility facilitates the optimal configuration for every light path, and therefore the minimum cost-per-Gigabit per kilometer for any type of network infrastructure. What’s more, it can transport a flexible combination of 400GbE, 100GbE and 10GbE Ethernet services as well as OTU4 client services. This gives users unique client port flexibility and a seamless way to migrate to higher client speeds without having to replace equipment in the future.
