The "East Data West Computing" project closely links data, computing power and network, which requires not only computing power network with super capacity, but also optical network to provide high-quality connectivity and super capacity. As an important component of the information infrastructure and key bearer base, optical network can meet the arithmetic demand for transmission bandwidth, capacity and low latency. As a communication network bearer cornerstone, optical transmission network is the infrastructure and prerequisite for the development of 5G, big data center, industrial Internet, artificial intelligence and other fields. Today, the cloud-network integrated infrastructure construction, driving the deep integration of arithmetic, cloud and optical network, empowering digital transformation in all industries. With this, the optical transmission network is also to ultra-high speed and large capacity, flexible and open, collaborative intelligent control and other diversification continues to evolve, from high-speed transmission technology at present 400G has opened commercial, 800G attention to further enhance the attention, how to further enhance the transmission capacity based on spectrum expansion has raised industry concerns. Along with the maturity and innovation of related technologies, optical networks are also being reconfigured through the network architecture to promote the transformation of networks from infrastructure networks to service networks, so as to better serve the digital economy. In the face of new infrastructure construction and industrial digital transformation and other development opportunities, China's optical communications industry is still facing multiple challenges in the evolution of network intelligence, the collaborative development of computing networks, green and low-carbon, and the expansion of application scenarios.
With the penetration of broadband and speed-up, gigabit intelligent optical network needs to change from bandwidth "gigabit" connection capability to bandwidth + experience "gigabit" service capability to meet the needs of gigabit service development in the digital era. The current gigabit optical access network uses 10G GPON + gigabit gateway + WiFi6 technology to fully realize the "end-to-end gigabit fixed network" capability, and with the scenario-based broadband experience dividend, PON + thousands of lines and industries to show the market value of the future PON network will continue to evolve in the direction of 50G, 50G PON technology development To be further standardized. For the rate upgrade of PON network, the current 50G PON optical module industry is still in the initial stage, how to improve the low latency technology of PON system to achieve multi-point cooperative networking, how to control the intelligent gateway to enhance the network experience? Based on this background, CIOE will invite three major carriers, PON equipment manufacturers and optical module manufacturers to work together with upstream and downstream to promote the development trend of gigabit intelligent broadband access network and the future 50G PON key technology research.
Global TOP-class hyperscale cloud service providers plan to build new data centers in multiple regions around the world, and data center spending is expected to surge 30% in 2022, with capital expenditures exceeding $20 billion. The expansion of data center construction scale will increase the demand for new server architectures and network upgrades, and will further impose new requirements on data center network transmission and operation technologies. With the rapid development of cloud data centers and the continuous rise of traffic, the development of data center optical interconnection network architecture has seen different evolutionary trends, from 400G to 800G, all the way to 6.4T, 12.8T and even to 25.6T after the future, which puts forward higher data center high-speed transmission technology from the network level, server and switch equipment capacity level, chip and module level. This puts forward higher demands on data center high-speed transmission technologies from the network level, server and switch equipment capacity level, chip and module level. The evolution of switch chip capacity, optical module technology, opening and decoupling of optical network, development of data center industry standard and industry collaboration still need to be discussed by the industry upstream and downstream. In view of this, CIOE invites Internet service providers, data center equipment vendors and core module device vendors to jointly hold the Data Center Optical Interconnection Evolution Trend Forum, focusing on the future development trend of data center high-speed transmission network interconnection.
In the 5G Internet, cloud computing, big data and other new high-bandwidth services and applications continue to promote the carrier telecommunications market, network service traffic and data center optical interconnection network evolution and upgrading of the use of optoelectronic chip rate requirements, design processes, packaging forms, performance technology requirements upgrade. Optical chips carry an important role in key business scenarios, but the localization rate of China's core optical communication chips is still relatively low, at present, China's high-end laser chip technology and products still rely mainly on imports, high-speed rate of 25Gb / s and above optical communication chips localization rate of no more than 15%. In the face of foreign technology blockade, the domestic optical chip local market how to respond? How to effectively overcome the optical chip integration technology, wafer manufacturing and chip testing and packaging technology, the upstream and downstream industry chain of optical chips still need to face the optical chip industry together and discuss together. Therefore, CIOE will invite the upstream and downstream companies and experts in the optical chip industry to participate in the "Optical Chip Design, Manufacturing and Packaging Technology Forum" for in-depth communication and discussion.
Currently, the Internet development has entered the big data era, and will embrace the all-cloud era. 5G, cloud computing, and AI are integrated with industries for data association. In the future, the human society will evolve into a smart society. In the cloud era, the explosive traffic growth will push the throughput of data centers to a new height. In this context, the rate of Ethernet interfaces will evolve from 400 Gbit/s to 800 Gbit/s and then 1.6 Tbit/s, and the switching capacity will develop from 12.8 Tbit/s to 25.6 Tbit/s or even 51.2 Tbit/s. The evolution path to beyond 100T can be expected. IPEC is an international optoelectronics standards organization. After two years of development, IPEC has grown from 13 members to nearly 40 members from different domains in the optoelectronic industry. With the joint efforts of IPEC members, great research achievements have been made, covering cutting-edge optical input/output (OIO), 800G interface standards, interoperable test platforms, 50G and 100G BIDI interface standards in the next-generation wireless optical solution, and optical network intelligent O&M.
Surging demand for Cloud services, especially those enabled by AI applications, has accelerated the adoption of next generation optical technologies. The innovations being adopted include 800G and 1.6T optical transceivers and AOCs, co-packaged optics and even optical switching. Can the industry supply chain keep up with the market demand and invest into development of new products? Is there an opportunity for new materials and device designs? How will datacenter architectures change in the future?
