The ability to provide increased capacity per fibre with fewer wavelengths and less equipment creates compelling economics for accelerated 800G coherent adoption in 2022
of technological innovations. As one might expect, the near
symbol rates, third-generation digital subcarriers, and long-codeword probabilistic constellation shaping are enabling superior performance vs. prior generations at 800G but also at 700G, 600G and 400G. Programmability also means 800G technology is applicable to more networks at any reach including fixed or flexgrid channel spacings and legacy or modern fibre optic cables. The ability to provide increased capacity per fibre with fewer wavelengths and less equipment creates compelling economics for accelerated 800G coherent adoption in 2022.” Brandon Collings, chief technology officer, Lumentum “Network traffic growth is continuing unabated as consumer video consumption expands and internet- enabled devices widely proliferate. Similarly, the need to satisfy this growth without comparable increases in cost and power consumption is equally present. However, neither of these market demands are historically new, and the optical communications industry has been effectively satisfying these demands through generations
Accessibility to broadband networks and the Internet is also a part of 2022’s story. The US$1.2 trillion infrastructure bill that recently passed the US Congress contains US$65 billion for improved high-speed internet access and affordability. US$42.45 billion is earmarked for grants to states for broadband projects. Prior to passage of the infrastructure bill, the United States Department of Agriculture (USDA) ReConnect Program appropriated US$1.3 billion to help bring high-speed broadband to rural and underserved communities and the 2020 CARES (Coronavirus Aid, Relief, and Economic Security) Act also provided incremental broadband funding. In a recent ACG Research report residential broadband capacity demand was projected to grow 46% annually through 2025 (see blog). Acceleration of 800G coherent DWDM embedded optical engines like Infinera’s ICE6 will help network operators cost- effectively address growing capacity demands for their optical transport networks in 2022 and beyond.
future will not be that different in regard to this trend, although the technical approaches to address these challenges will likely be. The industry has widely known about the limitations Shannon’s Law places on the spectral efficiency of our optical transmission networks for some time; however, we are now tangibly beginning to experience this limitation within our networks. Therefore, approaches that increase the amplified bandwidth within our networks will increasingly become critical and mainstream. This includes more extensive use of both C- and L-bands and multiple fibre pairs per route. Vital to this being successful is the realisation of a cost-effective increase in the integration level of the optical equipment, which can support both C- and L-bands or can support multiple fibre pairs per degree. As an industry innovator and leader in supplying such optical equipment, one can expect such next-generation enabling integration from Lumentum will become a reality in the coming year.”
