Description du produit

1. Product Overview

TNV1T302 is a cost-effective wavelength division circuit board launched by Huawei OSN9800 series optical transmission platform for mainstream markets, carrying the strategic mission of popularizing and scaling up over 100G optical transmission technology.This board achieves a transmission capacity of 1.2Tbit/s on a single board, perfectly balancing the three core elements of performance, deployment cost, and operational complexity.It is the most popular wavelength division solution in scenarios such as metropolitan core networks, regional backbone networks, and large enterprise private networks.

As a model product under the dual wheel drive strategy of"commercial success" and"technological leadership", TNV1T302 inherits the excellent genes of the OSN9800 platform.Through architecture optimization and economies of scale, it reduces single bit transmission costs by more than 40% while maintaining carrier grade reliability and rich functional characteristics.Against the backdrop of large-scale deployment of 5G, digital transformation of enterprises, and deep penetration of cloud computing, this board provides network operators and enterprise customers with the optimal technological path for smooth evolution from 10G/40G networks to 100G/200G networks.It is a cornerstone product for building the next generation of high-quality transmission networks.

2.Precision optimized technical specifications

Transmission performance and configuration flexibility

The TNV1T302 board provides a total transmission capacity of 1.2Tbit/s and supports two highly flexible configuration modes: 12 × 100G mode or 6 × 200G mode.It can be switched with one click through software commands without the need to replace any hardware components.This design enables customers to invest in stages based on actual business growth.Initially, it can be deployed in a 100G mode to control costs, and in the future, it can be smoothly upgraded to a 200G mode when business demand grows, maximizing the protection of existing investments.

The wavelength tuning range covers the standard C-band, specifically from 1528.77nm to 1566.72nm, supporting standard 50GHz and 100GHz wavelength grids.Each channel adopts tunable laser technology with a tuning accuracy of ± 2.5GHz, ensuring precise wavelength alignment in a multi vendor environment and avoiding inter channel interference.The modulation format is optimized for mainstream transmission distances and supports two of the most mature and reliable modulation methods, DP-QPSK and DP-16QAM, which can be configured and selected through software.DP-QPSK mode is suitable for medium to long distance transmission of 200-1500km, with excellent anti nonlinear capability and transmission resilience;DP-16QAM mode is suitable for urban and regional transmission within 80-500km, achieving doubled spectrum efficiency within a limited distance.

Forward error correction adopts Huawei's sixth generation enhanced soft decision FEC technology, achieving a net coding gain of 10.5dB with 15% redundancy overhead.This FEC scheme achieves the best balance between performance and complexity, providing sufficient system margin to cope with various link degradation scenarios while avoiding power consumption and cost increases caused by excessive computational complexity.In terms of actual transmission performance, on G.652 standard single-mode fiber, the 100G DP-QPSK mode can achieve relay free transmission for 1200km with an OSNR tolerance of 15dB;the 200G DP-16QAM mode can achieve transmission for 500km with an OSNR tolerance of 18dB.

Robust and reliable hardware design

The board adopts the standard single board specification of OSN9800 platform, with a height of 1U and a depth of 300mm, and can be installed in any business slot of OSN9800 U32 and U64 subracks.The front panel is equipped with 12 LC/PC duplex optical interfaces, which are hot swappable CFP2 optical modules and support various industrial standard optical modules such as 100G LR4/ER4 and 200G FR4/LR4.This modular design gives great flexibility to network deployment, allowing customers to choose the most suitable optical module based on transmission distance and cost budget, and in future technology upgrades, only the optical module needs to be replaced instead of the entire board.

The power management has been carefully optimized, with a typical power consumption of 220W in a 12 × 100G full load working state and 250W in a 6 × 200G mode.By using Huawei's self-developed third-generation intelligent power management chip, the board can dynamically adjust the power supply voltage and clock frequency of each functional unit according to the business load, and the power consumption can be reduced to below 120W in a light load state.The working temperature range meets the commercial grade requirements of the standard (0°C to+45°C), and the storage temperature range is -40°C to+70°C, suitable for deployment environments in the vast majority of data centers and communication rooms.

Reliability design follows telecom grade standards, with a calculated mean time between failures (MTBF) of over 200000 hours, equivalent to continuous fault free operation for over 22 years.The key components adopt industrial grade screening standards, and all optical interfaces have 15kV electrostatic discharge (ESD) protection capability.The board supports online hot plugging, which can be replaced or upgraded without interrupting other services, greatly improving the maintainability of the network.

3.Mature and complete functional features

Intelligent light layer management function

TNV1T302 integrates Huawei& # 39; s mature intelligent optical performance monitoring system, which can monitor more than 20 key parameters such as input/output optical power, center frequency offset, optical signal-to-noise ratio (OSNR), polarization related loss (PDL) of each channel in real time. The monitoring data is sampled at a frequency of 1Hz and uploaded to the network management system through the unified management channel of the OSN9800 platform, providing comprehensive visibility for network operation and maintenance.

The board supports automatic power balancing function, which can detect the power difference between each channel and automatically adjust the adjustable optical attenuator (VOA) to ensure that the output power of all channels remains within the ±0.5dB range of the set value.This balancing function is crucial for maintaining stable OSNR performance of the system, especially in long-distance transmission through multiple optical amplification stations.The system also supports automatic wavelength re tuning function.When the wavelength of a certain channel deviates from the nominal value by more than ± 5GHz due to temperature drift or other reasons, the re tuning process can be automatically initiated without manual intervention.

The fault diagnosis function integrates Huawei's years of on-site experience and can identify over 50 common optical layer fault modes.When performance degradation is detected, the system not only issues an alarm, but also provides possible cause analysis and handling suggestions based on a preset knowledge base.For example, if the OSNR of a certain channel suddenly drops while other channels are normal, the system will suggest checking whether the fiber optic connector corresponding to that channel is contaminated;If the OSNR of all channels decreases simultaneously, it is recommended to check the pump laser status of the optical amplifier.

Multi level business protection mechanism

TNV1T302 supports comprehensive protection solutions from device level to network level.Within the board, key functional units such as power modules, control chips, and memory devices are designed with redundancy, ensuring that a single device failure does not cause business interruption.At the optical module level, 1+1 backup is supported, and each business channel can be configured with two primary and backup optical modules.When the primary module fails, it can be switched to the backup module within 50ms.

At the network level, the board supports a complete OTN protection mechanism, including on-board 1+1 protection, sub rack 1:1 protection, channel protection based on ODUk SNCP, and optical layer protection based on OSNR monitoring.Of particular note is the intelligent power balancing and protection linkage function: when the system detects an abnormal increase in attenuation of a certain section of fiber, it can attempt to automatically increase the transmission power to compensate for the additional attenuation before triggering protection switching.If the performance returns to normal after power adjustment, unnecessary protection switching is avoided.This intelligent processing strategy significantly reduces business interruptions caused by transient events.

For the business isolation needs that enterprise customers are particularly concerned about, the board supports hard pipeline isolation technology based on ODUflex.Each physical channel can be divided into multiple logical pipelines, and strict time-division multiplexing and cache isolation mechanisms are used between pipelines to ensure that any sudden flow or failure of a pipeline will not affect other pipelines.This mechanism provides a solid technical foundation for enterprise customers to carry various types of traffic such as production, office, and backup services on the same physical network.

Simplified operation and integration experience

One of the design philosophies of TNV1T302 is"out of the box, simplified operation and maintenance".The board has completed pre calibration and wavelength calibration of all optical components before leaving the factory.After power on, it can be put into use by simply configuring the business through the network management system.Huawei provides standard device configuration file templates, allowing customers to choose the appropriate template based on their network planning, greatly reducing deployment time.

The deep integration with Huawei's NCE-T intelligent control system has brought revolutionary operation and maintenance experience.Through the visual interface of NCE-T, operation and maintenance personnel can intuitively view real-time performance data, historical trend curves, and alarm statistics for each channel.The system supports policy based automation operations, such as setting rules: when the pre FEC error rate of a certain channel exceeds 1E-4 for 5 consecutive minutes, diagnostic testing will be automatically initiated and a report will be generated;When sufficient performance margin is detected during the low season of nighttime business, the transmission power is automatically reduced to save energy consumption.

For multi vendor environments, TNV1T302 fully supports the standard NETCONF/YANG model and TL1 command set, enabling seamless integration with third-party network management systems.Huawei also provides an open northbound API interface, which supports customers to deeply integrate their own operation and maintenance processes with device management, achieving customized operation and maintenance automation.

4.Widely applicable deployment scenarios

Urban core network traffic aggregation

In modern urban network architecture, TNV1T302 is usually deployed at the core nodes of the urban area, playing a key role in aggregating multiple access ring traffic and forwarding it to the backbone network.The typical configuration is: using a 6 ×200G mode, with 4 channels used to connect the aggregation rooms in various regions, 1 channel used to connect to the provincial backbone network, and 1 channel reserved for future expansion or as a protection channel.

In this scenario, the intelligent function of the board is fully demonstrated.The characteristic of a metropolitan area network is the significant day night fluctuations and suddenness of business traffic.The dynamic power adjustment function of TNV1T302 can optimize the transmission power based on real-time traffic load, reduce power consumption during low traffic periods, and ensure performance margin during peak periods.The automatic wavelength tuning function simplifies the network expansion process.When a new aggregation node needs to be added, simply install a new device and specify an idle wavelength.The system will automatically complete wavelength alignment and power balance, shortening the traditional manual debugging work that takes several days to a few minutes.

For the common short-range transmission in metropolitan area networks (usually<80km), the board can be configured in DP-16QAM mode to achieve higher spectral efficiency.Under the standard C-band 50GHz grid, a single OSN9800 subrack fully equipped with TNV1T302 cards can provide up to 9.6Tbit/s of metropolitan core capacity, sufficient to meet the traffic growth demand for the next 5-8 years.

Backbone of large enterprise private network

For large enterprises such as finance, energy, manufacturing and the Internet, TNV1T302 provides an ideal choice for building a private optical transmission backbone network.Enterprise private networks typically connect data centers, research and development centers, production bases, and branch offices located in different cities, with extremely high requirements for network reliability, security, and controllability.

In this scenario, the hard pipeline isolation function of TNV1T302 played a core value. An enterprise can divide a physical channel into multiple ODUflex pipes, which respectively carry different types of traffic such as key business systems (such as core trading systems, ERP systems), office business (video conferencing, file sharing), and Internet access. Each pipeline has independent bandwidth guarantees and QoS policies, and complete isolation between pipelines ensures that core services are not disrupted by other traffic.

In terms of security, the board supports linkage with security devices such as Huawei firewalls and intrusion detection systems to implement security policies based on the optical layer.For example, rules can be configured: when a security device detects abnormal traffic from a branch, it can notify the transmission device through the NETCONF interface to temporarily shut down the transmission of the corresponding channel, and resume business after the threat is resolved.This cross layer security collaboration provides enterprises with defense in depth capabilities.

Backpropagation in 5G carrier network

In the construction of 5G networks, TNV1T302 plays an important role in the intermediate and return layers of the carrier network.The large-scale deployment of 5G base stations has brought a massive amount of forward traffic, which needs to be transmitted to the regional center computer room through the intermediate transmission network after aggregation at the access layer, and then transmitted to the core network element through the return network.

The flexibility of TNV1T302 perfectly matches the requirements of 5G bearer.In the early stage of 5G construction, the business traffic is relatively small and can be deployed in a 12 × 100G mode, with each channel carrying a region's intermediate transmission traffic.With the growth of 5G users and the enrichment of services, it can be smoothly upgraded to 6 × 200G mode, doubling the capacity without the need to replace hardware.The optimization of low latency transmission by the board is particularly suitable for 5G uRLLC (ultra reliable low latency communication) services.By optimizing cache management and scheduling algorithms, end-to-end transmission latency can be ensured to be stable within 200 microseconds.

In response to the demand for 5G network slicing, the board supports splitting physical channels into multiple virtual network slices, each with independent bandwidth, latency, and reliability guarantees.For example, a high priority slice can be allocated for the industrial control business of a smart factory to ensure its bandwidth and latency requirements;Allocate a best effort slice for the mobile broadband service of public users and share the remaining bandwidth resources.This refined resource management capability is the key to achieving multi capability in 5G networks.

5.Economic Analysis and Investment Protection

Total Cost of Ownership (TCO) Advantage

One of the core competitive advantages of TNV1T302 is its outstanding overall cost of ownership performance.Compared with the decentralized equipment solution of the same capacity, adopting the TNV1T302 single board integration solution can save about 30% of equipment procurement costs, about 60% of data center space, and about 40% of power consumption.If indirect costs such as installation, testing, operation and maintenance management are taken into account, the TCO advantage is even more obvious.

The cost advantage stems from innovation in multiple aspects: chip level high integration reduces the number of components;Intelligent power management reduces power consumption;Simplified operation and maintenance reduces manpower investment;High reliability design reduces spare parts inventory and maintenance costs.Huawei also offers a flexible business model, where customers can choose from various options such as one-time purchase, installment payment, and capacity leasing, and select the most suitable procurement plan based on their cash flow situation.

Investment Protection and Smooth Evolution

In the rapidly iterating optical communication industry, investment protection is one of the most concerning issues for customers.TNV1T302 has been designed with long-term evolution capability in mind.The hardware platform adopts a modular design, and key components such as optical modules, processors, and memory are independently upgradable.The software architecture supports online upgrades, and the addition of new features and optimization of performance can be achieved through software updates without the need for hardware replacement.

The most commendable feature is its ability to smoothly evolve towards higher rates.The 100G network currently deployed by the customer can be upgraded to 200G in the future by executing a mode switch command on the network management system and replacing the corresponding optical module.The entire process can be carried out without interrupting the business.This smooth evolution capability minimizes the risks and costs of network upgrades.

Scale effect of ecosystem

As the main product of Huawei OSN9800 platform, TNV1T302 benefits from its large installation base and mature ecosystem.Thousands of TNV1T302 cards have been running stably in the network worldwide, accumulating rich deployment experience and best practices.These experiences are systematically summarized and integrated into product design improvement, document writing, and training courses, enabling new customers to quickly grasp product features and successfully deploy them.

A mature ecosystem also means rich third-party support and integration experience.Mainstream optical module suppliers, network management software developers, and system integrators all have a deep understanding and support for TNV1T302, allowing customers to easily access various supporting products and services.Huawei's partner program also ensures that customers can find experienced service providers when they need customized development or special integration.

6.Service System and Success Guarantee
