Native hard pipe (NHP) is a TDM-based hard pipe that features high security, low latency, and deterministic experience. The NHP technology integrates the transport network and access network, implementing multi-network integration and bearing the power and transportation production network, video surveillance network, IoT network, and office network. Huawei OptiXtrans E6600 products are the main devices used on the NHP target network.
The NHP target network uses the VC technology to carry SDH services on the live network and uses the OSU technology to carry video and IoT services. This ensures 100% security and reliability of the power production network and supports smooth evolution to new bearer systems, promoting digital transformation of the power production network. Huawei OptiXtrans E6600 and OptiXtrans E9600 products fully support the NHP technology and are applicable to power transmission and transformation scenarios in the electric power industry.
The OSU over PON technology introduces NHPs to the access network. Different OSU hard pipes carry different network signals, implementing convergence of multiple networks. OSU hard pipes can ensure secure transmission and isolation of different network signals. With OSU hard pipes, the power distribution communication network can enjoy both the low-cost FTTM and high-quality experience of NHPs.
In railway scenarios, secure and reliable bearer communication networks are required for telephone, SCADA, GSM-R, LTE-R/5G-R, future information networks, and video surveillance signals. NHPs can carry multiple networks and provide 100% physical isolation capability to ensure secure and stable information transmission between networks and support secure and reliable operation of the entire railway service.
The development of smart subway services and video cloud drives the bandwidth improvement and architecture upgrade of subway bearer networks. The bandwidth of the bearer ring network will gradually increase from 100G to 200G or even 300G. The network architecture will be compatible with various service transmission modes, such as multicast and one-hop cloud access. In the Smart 300G solution, a 100G gray ring network can be constructed first, and then a 200G colored ring network can be deployed. This solution not only inherits the efficient multicast capability of MRPS, but also supports bearing and bandwidth expansion for one-hop cloud access services. In this way, efficient bearing of subway services is achieved.
The PON-based FTTO all-optical campus solution uses a point-to-multipoint (P2MP) star network structure, which adapts to the north-south traffic model of cloud services and effectively meets the bandwidth increase requirements of cloud services. In addition, the TDM hard pipe isolation enables one physical network to carry multiple service networks, greatly improving the network bearing efficiency.
In the FTTO all-optical campus solution, passive optical splitters replace active devices, extending fibers to classrooms, dormitories, and offices. A range of optical network units (ONUs) are provided for different campus application scenarios, greatly reducing the number of extra-low voltage (ELV) rooms. In addition, with the OLT's 40 km long-distance transmission capability, one fiber connects the education bureau and primary and secondary schools, supporting the high-quality and balanced development of education resources in general education scenarios.
In the FTTO all-optical campus solution, fibers are directly routed to multiple places, such as wards, offices, and CT rooms, with one ONU supporting the access of multiple services. The bidirectional 10G SFP ONU can quickly send back CT images, migrating data to the cloud within seconds and improving image reading efficiency by 30 times. The solution supports TDM hard pipes and integrates the extranet, intranet, and device network, ensuring network information security and greatly improving O&M efficiency in the hospital.
In the FTTO all-optical campus solution, fibers are directly routed to guest rooms, corridors, and halls. One fiber carries three wavelengths separately for telephone, CATV, and Internet access (Wi-Fi and fixed network) services. By deploying just one fiber per room, cabling in guest rooms is effectively reduced. A single fiber can transmit signals for a maximum of 40 km, reaching geographically dispersed hotels, reducing the deployment of outdoor cabinets, and simplifying network deployment.
Online joint control of urban traffic is rapidly gaining traction. The FTTM all-optical intersection solution reconstructs the intersection network system. Just one optical cable and one electrical cable need to be deployed to support traffic light control, ePolice data backhaul, and checkpoint data backhaul over one network. Compared with the traditional network that uses more than 100 cables, the FTTM all-optical intersection solution shortens the construction period from 2 weeks to 1–2 days, improving the efficiency by 80%, and reducing the TCO by over 30%.
In the port scenario, the FTTM solution featuring deterministic low latency and high bandwidth implements a new super-distance control mode for containers hundreds of kilometers away. Based on FTTM and OTN technologies, zero frame freezing occurs in port video images. The E2E latency from the urban control center to the port PLC controller is less than 2 ms, improving the container operation efficiency by more than 30 times. Huawei OptiXstar T823E-D is an industrial ONU that provides 10G bandwidth and supports a wide working temperature range of –40°C to +70°C. This sophisticated product can carry multiple types of services such as ultra-HD video and PLC signals.
In the highway scenario, Huawei's FTTM solution introduces the OSU technology to the access network. Based on E2E hard pipes, this powerful solution ensures stable backhaul of various services, including toll collection, video along roads and tunnels, and high-speed IoT. Huawei OptiXstar P622E is a dual-uplink ONU that provides Type C full-link protection and network-level redundancy protection, ensuring reliability for services such as toll collection.
In the mining scenario, Huawei's FTTM solution features underground pre-connection and intrinsic safety, providing high security and easy deployment for customer networks. Thanks to the passive optical splitter and intrinsically safe optical ring end (ORE), there is no need for explosion-proof boxes in a mine. The application of the pre-connection technology avoids underground fiber splicing and improves the installation efficiency by more than 10 times. Huawei OptiXstar T863E-DE is an intrinsically safe ORE with an industrial-grade design and support for Type B and Type C full-link protection, delivering a link switching latency of less than 30 ms. This ground-breaking product provides high security and reliability for Wi-Fi, sensing, camera, and control services in mines.
In the manufacturing industry, informatization and intelligence have helped achieve new levels of productivity. All-optical industrial networks feature simple architecture, high stability and reliability, and flexible adjustment, providing real-time online network bearing for data backhaul of HD production line videos and IoT signals, as well as facilitating digital innovation of manufacturing enterprises. Currently, Huawei's solution has been put to work in various manufacturing scenarios, helping manufacturing enterprises such as Fast, VOYAH, and Risen Energy improve quality and efficiency.
In the metro station scenario, Huawei's FTTM solution leverages passive aggregation and long transmission distance, providing high security and easy deployment for station networks. Passive optical splitters are used for network aggregation, reducing ELV wells and cabling footprint at stations, simplifying network deployment, and mitigating fire risks. Self-growth networking facilitates fast deployment of new IoT connections in smart stations. Huawei OptiXstar T823E-D is an industrial ONU that provides 10G bandwidth and can work within a wide temperature range of –40°C to +70°C.
