Richard Jin, head of Huawei Optical Product Line, spoke on “Unleashing the Potential of Fiber and Moving Toward the F5.5G” at the 8th Ultra Broadband Forum (UBBF 2022). In this lecture, he emphasised the value of fibre communication for society’s advancement and outlined Huawei’s eight major technological advances in optical access and transmission, as well as the advantages they provide to the market. Jin urged everyone in the supply chain to cooperate in order to promote the F5.5G.
Future strategic infrastructure now includes fibre network infrastructure. Technology advancements in fibre production and sensing will further unleash fiber’s potential and open up new businesses throughout the transition from F5G to F5.5G. Huawei has developed 8 technology breakthroughs for F5.5G to hasten the industry’s development.
1. 50G PON Compatibility:
ITU-T has introduced the next-generation PON technology known as 50G PON. Huawei enhances the transmission power and receiver sensitivity of 50G PON optical modules to reach 40 km coverage through component structure and process innovation. Additionally, Huawei uses ultra-high-precision mounting techniques to combine GPON, 10G PON, and 50G PON into a single port. In order to swiftly deliver a ubiquitous 10G experience, operators will be able to upgrade from GPON and 10G PON to 50G PON without having to rebuild their current networks.
2. Super C+L Spectrum:
Huawei has created a brand-new method for spectrum amplification and transmission bandwidth increase based on trials and inventions. Gas flow and heating temperature are accurately controlled during the manufacturing process to achieve high concentration doping and enhance L-band amplification gain. To achieve improved transmission performance, these advances enhance the bandwidth by 50% and the super C+L transmission spectrum by up to 12 THz. The 10G era is also introduced by single wavelength 400G and 800G speeds reaching 100 Tbps per fibre.
3. Optical Cross Connect (OXC) :
Reconfigurable optical multiplexers (ROADM) external fibre connections are reduced, the footprint of the total system is reduced by 90%, and power consumption is reduced by more than 60% thanks to Huawei OXC’s 3D dot matrix algorithm. Additionally, Huawei has created new materials for OXC liquid crystal on silicon (LCOS) in order to decrease the response time of Wavelength Selective Switching (WSS) LCD from 200 ms to 100 ms, implement advanced preparation and protection of the fastest wavelength, and construct green and flexible all-optical networks.
4. OptiX Alps-WDM:
To address the issues of unequal service distribution, low resource utilisation, and challenging planning in metro networks, Huawei introduces the ground-breaking Metro WDM OptiX Alps-WDM pooling solution. At the metro access layer of the star network design, wavelengths can be shared across different access rings and prepared and adjusted flexibly using Huawei-developed WSS, a metro coherent module, and digital optical tag technologies. These solutions allow operators cut OPEX by 20% while increasing bandwidth by 10 times and reducing carbon emissions by 90%.
5. Flexible optical service unit (OSU) service granularities:
OSU core hard pipe technology from Huawei employs connections that range from 2 Mbps to 100 Gbps. Flexible bandwidth adjustments are possible without disrupting services. Reduced service transmission latency is achieved by simplifying the encapsulation mechanism. With the aid of this invention, operators may create premium OTN WDM networks with high bandwidth, extremely low latency, and deterministic experiences, increasing their ability to attract high-end clients.
6. FTTR C-WAN Architecture:
Home Wi-Fi networks must provide extensive coverage, high levels of stability, and high concurrency due to the increase in smart home appliances. However, each optical network terminal (ONT) in conventional Wi-Fi networks takes decisions on its own, which can lead to issues like interference and service instability in high-concurrency situations. The C-WAN centralised management and control architecture is used by the Huawei FTTR for Home Solution to coordinate all ONTs throughout the whole FTTR network, minimising interference and enhancing bandwidth performance. Additionally, the special smooth roaming technology can reach roaming handover times of 20ms or less, offering a fresh take on the digital home.
7. Fiber iris technology:
ODN accounts for a sizable chunk of FTTH investment. However, challenges with ODN maintenance and operation have long had an impact on the industry. The manual registration of port resources in the past produced resource errors, which in turn led to poor service delivery. In order to label a vast number of fibre ports, Huawei has introduced the ground-breaking fibre iris technology. This enables accurate real-time recording and allocation of port resources, facilitating quick service provisioning. With an accuracy of one metre, fault areas are promptly and correctly identified using oDSP and AI algorithms.
8. Autonomous networks:
The scale of the network will ten-fold in the future, and smart networks for autonomous vehicles will become the norm. Huawei has achieved a number of technological advancements in the realm of networks for autonomous driving. For instance, StellarGo implements tailored suggestions based on various customer patterns and replaces manual and single-factor route selection with intelligent multi-factor route selection and policies in transportation networks. Route selection is successful 99% of the time, and service delivery is 70% more efficient. Also,
According to Jin, Huawei will continue to make technology advances and product improvements based on earlier advancements when 10G connections become commonplace in 2025. Huawei will also increase the commercial value for operators by enhancing user experience and network operating efficiency. network travelling toward F5.5G. Richard Jin urged the entire industry to work together to advance F5.5G and promote the F5.5G business.
