DUBAIUnited Arab Emirates, October 13, 2023 /PRNewswire/ — During UBBF 2023, Richard Jin, President of Huawei’s Optical Product Line, delivered a keynote speech titled “Bringing F5.5G to Reality: Milestones on Our Journey to an Intelligent World”. In his speech, Richard first proposed the concept of three-phase network construction. Specifically, there are three driving forces for network development, namely video (100 Mbps network), experience (1 Gbps network) and intelligence (10 Gbps network). In this context, Huawei launched the F5.5G oriented three-phase all-optical target network architecture: all-optical coverage for 100 Mbps home broadband, all-optical connections extending to 1 Gb/s in every room and all-computing optical for 10 Gb/s everywhere. The three-phase construction of the all-optical target network can meet the network connection requirements of hot services in each phase, thus making F5.5G a reality and progressing towards an intelligent world.
Phase 1: All-optical video coverage for 100 Mbps home broadband
With the continuous improvement of video resolution and the rapid popularization of video interaction and immersive XR, the bandwidth increases from 10 Mbps to 100 Mbps and 1000 Mbps. In this phase, HD video and video interaction become the main driving force to achieve the goal of building an all-optical network with a home broadband speed of 100 Mbps. Operators should fully move towards FMC and replace copper lines and cables with a fully optical FTTH network. Serialized AirPON can accelerate FTTH construction and support GPON and 10G PON compatibility, enabling rapid provision of Gigabit services in hotspot areas. Meanwhile, operators need to deploy OTN on the metropolitan aggregation layer and build 3D mesh 400G backbone networks, supporting non-blocking bandwidth and zero video lag. Typical technology innovations in this phase include FlexPON, DQ ODN, and high-performance 400G.
Phase 2: Experience-based all-optical connections extending 1 Gbps to rooms
With increasingly diverse digital applications, fibers are being extended from living rooms to bedrooms, offices and kitchens, enabling “click-and-go” applications and providing an immersive network experience. All these developments impose higher requirements on network coverage, bandwidth, latency and roaming. In this phase, users are willing to pay for a more premium home network experience. Therefore, ensuring end-to-end (E2E) service experience becomes the key to achieving the goal of all-optical connections and 1Gbps expansion in every room. Operators need to upgrade 10G PON to fully provide Gigabit services, introduce fiber to the room (FTTR), 100G metro OTN to CO, non-blocking ultra-high-speed 400G backbone. Typical technological innovations of this phase are FTTR, metropolitan pooling WDM and intelligent network management and control system.
Phase 3: All-optical, intelligence-driven computing for 10 Gbps everywhere
AI accelerates content manufacturing and drives intelligent transformation of industries. To cope with traffic increases and massive data migration to the cloud, an IT-centric network is required to provide bus-level connection capabilities. Similar to the processor, bus and accessories of a computer, the computing power and storage of the data center (DC) must exchange information with end users in real time through a high-performance network to achieve the goal of the all optical. computing for 10 Gbit/s everywhere.
In this phase, the system based on FTTR all-optical domestic bus supports connection and play of IoT devices and integrates connection, sensing, computing and storage capabilities for 10 Gbps throughout the home. Furthermore, the all-optical cloud bus based on 50G PON and 800G OTN, it implements single-hop fully optical user-DC or DC-DC connections. Typical technological innovations in this phase include 50G PON, all-to-CO metropolitan OTN, and 800G backbone. Additionally, OTN should be designed for DC scenarios. Based on this, Huawei launched Kepler, the next-generation OTN platform, providing single-bin switching capacity of more than 100T. By leveraging new materials and structures, Kepler reduces power consumption per Gbit by 65% and the power consumption efficiency (PUE) at 1.2. It also provides intelligent computing units to significantly improve connection efficiency.
The three-phase all-optical target network can ensure parallel evolution and smooth upgrade from F5G to F5.5G. According to Richard, “Operators need the most suitable all-optical target network construction solution in different development phases. So far, 100 Mbps has changed content, 1 Gbps changes the broadband experience, and 10 Gbps will change society. Let’s work together to bring F5 .5G into reality and move forward towards a smart world. »
