Powering premium private lines with All-Optical networks
The combination of fifth-generation fixed fiber (F5G) and 5G will accelerate the arrival of a fully connected, intelligent world. By 2025, 100 billion devices will be connected across the globe and 30 percent of homes will enjoy gigabit broadband; a total of 1.3 billion 5G subscribers will be using 5G networks, which will have covered 58 percent of the world's population; and around 337 million people and 10 percent of companies will use VR/AR. Moreover, all enterprises will use cloud services, 85 percent of enterprise applications will be deployed on cloud, and 180 ZB of data will be generated each year.
The explosive growth of 2C, 2H, and 2B services is driving carriers to accelerate full-service deployment. But, it’s a growth that presents a challenge for bearer networks. 5G requires a tenfold increase in network bandwidth, connections, and availability compared with 4G. It also requires a 90 percent decrease in latency, packet loss, and service provisioning time.
In the 2B arena, business private lines will open up the enterprise market as government and enterprise services migrate to cloud. In addition to offering secure, reliable, and carrier-class network services, carriers must provide one-stop, self-service, bundled cloud and network services that are agile and intelligent if they hope to remain competitive.
The near-obsolete and segmented point-to-point dump pipes of optical networks provide only physical connections that cannot meet the transmission requirements of new services in the 5G era. Transforming from connection-centric dumb pipes to experience-centric service transmission networks is a current priority of carriers.
ON 2.0: All-optical service transmission networks
Huawei has launched its ON 2.0 solution to help carriers build all-optical service transmission networks that offer faster speeds, new sites, and smart O&M, and enable carriers to deliver an outstanding service experience.
- Faster: Single wavelength 200G/400G is now the standard rate of next-gen optical transmission. Advancements in materials, chips, and algorithms have accelerated speeds towards the Shannon limit. Huawei's Super 200G solution doubles fiber capacity while slashing TCO with CFP2 green design. And Huawei’s latest 800G optical module supports multiple rates from 200 Gbps to 800 Gbps, 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 Tbps, reducing per-bit cost, and meeting the bandwidth requirements of new services.
- New sites: Advances in the optical and electrical layers promote the wide application of optical-electrical convergence and all-optical cross-connections, reducing the layers of the backbone and metro networks and enabling the 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 new Liquid OTN solution uses flexible hard pipe technologies to simplify 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.
- Smart O&M: The iMaster NCE intelligent management and control system achieves full-lifecycle management in optical networks, improving the private-line experience. Preventive maintenance through AI modeling reduces the network fault rate, while the cloud-based smart brain and network planning design ensure that resources are available and that traffic volume is predictable, so capacity expansion is rational and service provisioning fast.
Four ways All-Optical can boost profits for carriers
ON 2.0 will evolve optical networks from infrastructure networks to service transmission networks and enable new services. High-quality OTN government and enterprise private lines will emerge as an important service for carriers, providing an outstanding experience for business users that builds differentiated competitiveness. Carriers can boost profits in four main ways:
- Bandwidth: As hard pipes, OTN private lines inherently have ultra-high bandwidth. Next-gen Liquid OTN technology supports flexible bandwidth adjustment from 2 Mbps to 100 Gbps, 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 are a huge market. To compete in this market, latency, like bandwidth, will become a key marketable parameter of competitiveness. Huawei's OTN+NCE private-line transmission network features simplified architecture, one-hop transmission, and Liquid OTN technologies, achieving ms-level E2E latency. The iMaster NCE private line latency map implements visualized, manageable, and guaranteed private-line latency. It ensures an optimal service experience for enterprise customers, while allowing carriers to provide diverse 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 and exceeds 99.99% availability. ASON technology can protect services against multiple fiber cuts, automatically switching diamond services to available routes within 20 ms. The built-in AI chip can predict service interruptions so that configurations can be optimized in advance for smart O&M and risk prevention. Furthermore, a flexible network with multi-route protection can be provided to boost stability and the availability of data transmission. Carriers can provide SLA availability at various levels based on customer requirements.
- TTM: Huawei's iMaster NCE supports real-time visualization and unified management and control of network resources. Coupled with the plug-and-play CPE, the NCE supports the rapid online E2E provisioning of private line services, shortening service provisioning time to hours. Enhanced time sequence prediction using AI algorithms and historical data yields informed budgeting and procurement decisions, avoids urgent capacity expansion, and shortens TTM to within a week. Carriers can provide different TTM packages based on customer requirements.
Who’s using ON 2.0?
Huawei is at the forefront of transforming industries, promoting the industrial application of ON 2.0, and helping carriers develop business models.
- 2B private line: China's top three carriers have built more than 20 OTN private line networks with Huawei to meet increasing demand from government and enterprise customers, particularly financial services and Internet companies. In December 2019, Thailand's CAT and Huawei released the first high-quality OTN private line network in Thailand for medium and large enterprises in the public and private sectors, laying a solid network foundation for Thailand's 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 E2E latency. This solution meets the key transmission requirements of 4K live broadcasts and will be able to support ultra-HD video and VR in the future.
Huawei is also working with the world's leading carriers to explore service scenarios for next-gen optical networks, launching NetCity joint innovation projects and quickly implementing solutions with DevOps 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.
