As the 5G era unfolds, fixed networks are also heralding the era of Fifth Generation Fixed Network (F5G). The combination of F5G and 5G will accelerate the movement towards a fully connected, intelligent world. By 2025, there will be 100 billion connected devices in the world and 30% of homes will enjoy gigabit broadband. The number of 5G users will reach 1.3 billion and 5G networks will cover 58% of the world's population. Around 337 million people will use VR/AR, while the percentage of companies using AR/VR will increase to 10%. It is also expected that all enterprises will adopt cloud services, 85% of enterprise applications will be deployed on the cloud, and 180 zettabytes will be generated each year. 

Premium private line

The explosive growth of innovative 2C, 2H, and 2B services is driving carriers to accelerate full-service deployment. However, this explosive growth also poses greater challenges to bearer networks. Compared with 4G, 5G requires a 10-fold increase in network bandwidth, connections, and availability and a 90% decrease in latency, packet loss, and service provisioning time. Additionally, in the 2B field, business private lines will be the best method for carriers to penetrate the enterprise market, considering the all-out cloud migration of government and enterprise services. Therefore, in addition to offering secure, reliable, and carrier-class network services, providing one-stop, self-service, agile, and intelligent cloud & network bundled services will become a key competitiveness of carriers in cloud services.

The near-obsolete and segmented point-to-point dump pipes of optical networks provide only physical connections and are unable to meet the transmission requirements of new services in the 5G era. How we transform from connection-centric dumb pipes to experience-centric service transmission networks has become a major concern for carriers.

Optical Networking 2.0: Building an All-optical Service Transmission Network

Huawei, as a global partner, is committed to building a world-leading all-optical network solution and working with upstream and downstream players to promote the prosperity of the optical network industry. To address these challenges, Huawei has launched the Optical Networking 2.0 (ON 2.0) solution, which enables new speed, new sites, and new smart O&M to promote the evolution of the all-optical network industry, helping carriers build all-optical service transmission networks and provide superb service experience.

  • New speed: The single wavelength 200G/400G has become the standard rate of next-generation optical transmission. Through material, chip, and algorithm innovation, the rate is quickly approaching the Shannon limit. Huawei's Super 200G solution doubles the fiber capacity while significantly lowering the TCO with CFP2 green design. And Huawei’s latest 800G optical module supports multiple rates ranging from 200 Gbit/s to 800 Gbit/s, with industry-leading performance and spectral efficiency. Huawei has also launched the industry's first single-fiber Super C solution, achieving the industry's highest per-fiber capacity of 48 Tbit/s, reducing per-bit cost, and meeting the bandwidth requirements of innovative services.
  • New sites: The continuous innovation of the optical layer and electrical layer promotes the wide application of optical-electrical convergence and all-optical cross-connections, reducing the layers of the backbone and metro networks, and implementing unified transmission of 2C, 2B, and 2H services. Huawei's all-optical cross-connect OXC product is the world's only commercial product of its kind. It can build a 3D backbone network and support large-capacity all-optical grooming and one-hop connection between sites, implementing fast E2E service provisioning. Huawei's brand-new Liquid OTN solution uses flexible hard pipe technologies to simplify the architecture and adapt to premium private lines, premium video, and 5G integrated transmission scenarios, building an all-optical base for the 5G era and enabling the prosperity of various industries.
  • New smart O&M: The iMaster NCE intelligent management and control system is used to implement full-lifecycle management of optical networks. Huawei's innovative management and control system improves private line experience. In the O&M field, AI modeling is used to implement preventive maintenance and reduce the network fault rate. The cloud-based smart brain and network planning design ensure that resources are available and traffic volume is predictable to implement well-informed capacity expansion and quick service provisioning. 

All-Optical Service Transmission Networks Driving Business Success

In the ON 2.0 era, optical networks will evolve from infrastructure networks to service transmission networks, and more innovative services based on optical networks will emerge in the future. High-quality OTN government and enterprise private lines will be an important service of carriers. Huawei's OTN premium private line solution provides a superb experience and builds differentiated competitiveness, helping carriers generate greater profit by leveraging the following aspects:

  • Bandwidth: As hard pipes, OTN private lines inherently have ultra-high bandwidth. The next-generation Liquid OTN technology supports flexible bandwidth adjustment from 2 Mbit/s to 100 Gbit/s, meeting the high availability requirements of government and enterprise customers, while supporting the "pay-as-you-grow" business model. This will attract more private line customers. 
  • Low latency: Emerging network services is a huge market. To compete in this market, latency, like bandwidth, will become an important and marketable specification and a vital element for competitiveness. Huawei's OTN+NCE private line transmission network features simplified architecture, one-hop transmission, and Liquid OTN technologies to achieve ms-level E2E latency. The iMaster NCE private line latency map implements visualized, manageable, marketable, and guaranteed private line latency, ensuring an optimal service experience for enterprise customers while allowing carriers to provide more diversified latency packages based on customer needs.
  • Availability: Huawei offers the industry's most advanced ASON 2.0 technology, which supports large networks and automatic recovery in seconds, exceeding 99.99% availability. The ASON technology can protect services against multiple fiber cuts. Diamond services can be automatically switched from faulty routes to available routes within 20 ms, in the case of multiple fiber cuts. The built-in AI chip can predict service interruption so that configurations can be optimized in advance to implement smart O&M and prevent potential risks. Furthermore, a flexible network with multi-route protection can be provided to further improve stability and availability of data transmission. Carriers can provide availability SLAs of varying levels based on customer requirements.
  • TTM: Huawei's iMaster NCE supports real-time visualization as well as unified management and control of network resources. Coupled with the plug-and-play CPE, the NCE supports fast online E2E provisioning of private line services, shortening the service provisioning time to hours, helping enterprise users quickly launch new services to the market. Meanwhile, by using enhanced time sequence prediction, AI algorithms and historical data, it can make informed budgeting and procurement decisions, avoid urgent capacity expansion and shorten time-to-market (TTM) to within one week. Carriers can provide different TTM packages based on customer requirements. 

Accelerating Joint Innovation of ON 2.0 

Huawei has been at the forefront of transforming industries and promoting the industrial application of ON 2.0. Huawei has also helped carriers innovate their business models in many new fields to maximize their business value.

In December 2019, Thailand's CAT and Huawei released the first high-quality OTN private line network in Thailand, serving large- and medium-sized enterprises in the public and private sectors. This lays a solid network foundation for Thailand's 2020 digital transformation.
  • In the 2H video transmission field: Huawei helped China Mobile to launch its first OTN 4K live video broadcast network. This solution directly pushes live streams from video sources to the OLT through hard pipes, ensuring zero congestion, zero packet loss, and low latency from end to end. This solution meets the key transmission requirements of 4K live broadcast and can support ultra-HD video and VR in the future.

Looking to the future, Huawei is also working with the world's leading carriers to explore service scenarios for next-generation optical networks, launching NetCity joint innovation projects and using DevOps to quickly implement solutions that help carriers maximize business value. We believe that ON 2.0 will lead the global optical network industry into a new era. Huawei will work with carriers and industry partners around the world to jointly usher in a new era of optical networks and build a fully connected, intelligent world.
