Huawei: Unleashing Fiber's Potential and Striding to F5.5G

BANGKOK, Oct. 28, 2022 /PRNewswire/ — During the eighth Ultra-Broadband Forum (UBBF 2022), Richard Jin, President of Huawei Optical Business Product Line delivered a speech titled “Unleashing Fiber Potential and Striding to F5.5G”. In this keynote speech, he expressed the significance of fiber communication to society’s growth, and launched Huawei’s eight key technological breakthroughs in optical entry and transmission in addition to their advantages to the trade. Mr Jin referred to as on the entire trade chain to work collectively to stride F5.5G.

Fiber networks have develop into future-oriented strategic infrastructure. During the evolution from F5G to F5.5G, technological improvements in industrial manufacturing and fiber sensing will additional unleash the potential of fiber and open up new markets. For F5.5G, Huawei has made eight technological improvements to speed up trade evolution.

1. 50G PON compatibility: 50G PON is the next-generation PON know-how launched by ITU-T. Through part construction and course of innovation, Huawei improves the transmit energy and receiver sensitivity of 50G PON optical modules to obtain 40 km protection. In addition, Huawei integrates GPON, 10G PON, and 50G PON in a single port utilizing ultra-high precision mounting applied sciences. This innovation will assist operators easily improve from GPON and 10G PON to 50G PON with out reconstructing their reside networks, shortly offering ubiquitous 10G expertise.
   
   
   
   
2. Super C+L spectrum: Based on experiments and improvements, Huawei has developed a brand new resolution for spectrum amplification and transmission bandwidth enchancment. During the manufacturing course of, the gasoline flux and heating temperature are precisely managed to obtain excessive focus doping and enhance the amplification acquire of the L band. These improvements improve the tremendous C+L transmission spectrum to 12 THz, and improve the bandwidth by 50% for increased transmission efficiency. In addition, the 400G and 800G single-wavelength charges can attain 100 Tbps per fiber, ushering within the 10G period.
   
   
   
   
3. Optical cross-connect (OXC): Huawei OXC makes use of the 3D dot matrix algorithm to improve the cabling density of the all-optical backplane by 35%, reduces exterior fiber connections of reconfigurable optical add/drop multiplexers (ROADMs), reduces the dimensions of the complete system by 90%, and reduces energy consumption by greater than 60%. In addition, Huawei has developed new supplies for OXC liquid crystal on silicon (LCOS) to cut back the wavelength selective switching (WSS) LCD response time from 200 ms to 100 ms, implementing quicker wavelength grooming and safety, and constructing inexperienced and agile all-optical networks.
   
   
   
   
4. OptiX Alps-WDM: Huawei launches the modern Metro WDM pooling resolution OptiX Alps-WDM to resolve the issues of uneven service distribution, low useful resource utilization, and troublesome planning on metro networks. Using Huawei-developed WSS, a metro coherent module, and digital optical label applied sciences, wavelengths may be shared amongst completely different entry rings within the star networking structure on the metro entry layer, and may be flexibly groomed and adjusted. These applied sciences improve the bandwidth 10-fold and cut back the carbon emission by 90%, serving to operators cut back OPEX by 20%, obtain the goal community structure that strikes WDM networks to websites, and understand clean community evolution within the subsequent 10 years.
   
   
   
   
5. Flexible optical service unit (OSU) service granularities: Huawei’s modern onerous pipe core know-how OSU makes use of onerous pipe connections of two Mbps to 100 Gbps. The bandwidth may be flexibly adjusted with out interrupting providers. The encapsulation protocol is simplified to cut back the service transmission latency. This innovation helps operators construct premium OTN WDM networks with excessive bandwidth, ultra-low latency, and deterministic expertise, in addition to serving to operators win extra high-end trade prospects.
   
   
   
   
6. FTTR C-WAN structure: With the rise of sensible house home equipment, house Wi-Fi networks want to supply intensive protection, excessive stability, and excessive concurrency. However, in conventional Wi-Fi networking, every optical community terminal (ONT) makes selections independently, which causes issues reminiscent of interference and service instability in high-concurrency situations. Huawei’s FTTR for Home resolution makes use of the C-WAN centralized administration and management structure to coordinate all ONTs on the complete FTTR community, lowering interference and enhancing bandwidth expertise. In addition, the distinctive imperceptible roaming know-how can obtain roaming handover inside 20 ms, offering a brand-new digital house expertise.
   
   
   
   
7. Fiber iris know-how: The ODN accounts for a excessive proportion of FTTH funding. However, difficulties in ODN O&M have lengthy plagued the trade. In the previous, port sources had to be manually recorded, leading to useful resource inaccuracy which in flip led to service provisioning failures. Huawei has launched the modern fiber iris know-how to label massive numbers of fiber ports. In this fashion, port sources may be precisely recorded and allotted in actual time, enabling fast service provisioning. The oDSP and AI algorithms are used to precisely and shortly determine the fault places with a precision of 1 meter.
   
   
   
   
8. Autonomous networks: In the longer term, the community scale will improve 10-fold, and clever autonomous driving networks will develop into the mainstream. Huawei has made a number of technological improvements within the autonomous driving community discipline. For instance, StellarGo modifications guide and single-factor route part to multi-factor and multi-policy clever route choice on transport networks,, and implements customized suggestions based mostly on completely different buyer habits. The route choice success fee is as excessive as 99%, and the service provisioning effectivity is improved by 70%. In addition, the StellarCue builds numerous clever expertise fashions and implements one-minute notion of poor-QoE incidents based mostly on huge poor-QoE information coaching, which might considerably cut back person complaints.

According to Mr. Jin, with ubiquitous 10G connections due by 2025, Huawei will proceed to make technological breakthroughs and product improvements based mostly on the previous improvements, and create larger industrial worth for operators by enhancing person expertise and community operation effectivity on the way in which to F5.5G. Finally, Richard Jin referred to as for the joint efforts of the complete trade to promote the F5.5G trade and stride to F5.5G.
