2.Detailed technical specifications and parameters

Transmission performance specifications

The maximum transmission capacity of TNV3T220 single board reaches a record high of 4.8Tbit/s, achieved through 8 completely independent 600G channels in parallel.Each channel supports full rate adaptation and can be software switched between multiple rates of 600G, 400G, 200G, and 100G without the need to replace any hardware components.The line side adopts the latest OTUC3 standard packaging format, supporting a mapping structure of 3 × OTU4, and fully compatible with existing standards such as OTUC2 and OTU4.

The wavelength tuning range has made a breakthrough in covering the extended C+L band, specifically from 1524.29nm to 1611.79nm, with an available spectrum width of 87.5nm, which is more than three times the spectrum resources of the traditional C band.The wavelength grid configuration supports continuous adjustability from 25GHz to 150GHz, with a minimum tuning accuracy of 1GHz, achieving true elastic optical networks.

In terms of modulation format, the board supports a full range of software defined modulation from DP-256QAM to DP-QPSK.In laboratory environments, DP-256QAM can achieve spectral efficiency of up to 16bit/s/Hz.In actual commercial use, recommended configurations are based on different scenarios: DP-64QAM for ultra short distance data center interconnection (≤40km), DP-32QAM for urban areas (40-200km), DP-16QAM for regional backbone (200-800km), and DP-QPSK for ultra long distance national backbone (800-3000km).

Using Huawei's eighth generation Super Soft Decision Forward Error Correction (SD-FEC Pro) technology, a net coding gain of 14dB is achieved with 15% redundancy overhead, approaching 90% of the Shannon limit.In terms of transmission performance, DP-16QAM modulation can achieve 1200km wireless relay transmission on standard G.654.E ultra-low loss fiber, and DP-QPSK can reach 2500km.When using DP-256QAM optimized for short distance, experimental transmission of single wave 800G can be achieved within a range of 30km.

Hardware physical specifications

The board adopts the OSN9800 platform enhanced high-power single board design, with physical dimensions of 3U height x 320mm depth to meet high-density heat dissipation requirements.The front panel is equipped with 8 dual LC/PC optical interfaces, supporting 600G ZR+and 400G ZR/Zr+multi-mode adaptation.The interface optoelectronic characteristics fully comply with the OIF 600G-LR/ER implementation protocol and IEEE 802.3ct standard.

Power management adopts Huawei's third-generation intelligent power architecture, with full load operating power controlled within the range of 550-650W.Through adaptive voltage frequency adjustment (AVFS) technology, power consumption can be reduced to below 300W in light load mode.The working temperature range has been expanded to industrial grade -10°C to+65 ° C, supporting stable operation under extreme weather conditions.The storage temperature range has been expanded to -45°C to+90 ° C to ensure global transportation adaptability.The adaptability to environmental humidity has been improved to 0% to 100% relative humidity (non condensing), meeting special environmental requirements such as submarine cable equipment cabins.

3.Detailed explanation of core technical characteristics

Photon integration and cooperative transmission technology

TNV3T220 adopts Huawei's latest silicon optical integration technology, integrating more than 20 traditional discrete optical devices such as modulators, coherent receivers, tunable lasers, wavelength lockers, and optical power monitors on a single silicon optical chip.The chip is manufactured using 300mm silicon photonics technology, with an integration rate of over 1000 functional components per square millimeter.Silicon optical integration not only significantly reduces the size of the board, but also improves the alignment accuracy of optical components to the nanometer level, significantly improving system stability and consistency.

In terms of transmission technology, innovative multi carrier aggregation (MCA) technology has been introduced. Each 600G channel is actually composed of three 200G subcarriers aggregated, and the subcarrier spacing can be flexibly configured as 50GHz, 75GHz, or 100GHz. This architecture brings multiple advantages: firstly, through adaptive modulation at the subcarrier level, the modulation format of each subcarrier can be optimized for different frequency response characteristics of the fiber link; Secondly, flexible protection mechanisms can be implemented between subcarriers, and a single subcarrier failure does not affect the normal operation of other subcarriers; Finally, this architecture provides a smooth path for evolving towards higher rates, and in the future, capacity upgrades can be achieved by increasing the number of subcarriers or improving subcarrier rates.

Artificial Intelligence Enhanced Digital Signal Processing

The fifth generation oDSP chip installed on the board integrates a dedicated artificial intelligence acceleration engine, which includes 1024 parallel processing units and has a peak computing power of 25 TOPS (trillions of operations per second).The AI engine runs multiple deep learning models in real-time, including non-linear compensation models based on convolutional neural networks, polarization state tracking models based on recurrent neural networks, and power optimization models based on reinforcement learning.

The nonlinear compensation model can learn the nonlinear characteristics of fiber optic links in real time and establish an accurate inverse function model.Compared with traditional compensation algorithms based on digital backpropagation (DBP), the AI model improves compensation accuracy by 3dB and reduces computational complexity by 80%.The polarization state tracking model can maintain stable polarization demultiplexing even under extreme environmental disturbances such as strong winds, earthquakes, and day night temperature differences, with tracking speeds reaching millions of times per second.

The system has also established an end-to-end digital twin model, which simulates the system performance under various transmission conditions in the digital twin environment before actual data transmission begins, and automatically finds the optimal parameter configuration scheme.This"simulation first, implementation later" mode shortens the system tuning time from traditional manual testing days to automatic calculation minutes.

Quantum Security and Trusted Transmission Technology

Faced with the threat of future quantum computing to classical encryption algorithms, TNV3T220 integrates the classical channel transmission function of quantum key distribution (QKD).The board card reserves a dedicated quantum channel wavelength (usually 1550.12nm), which is transmitted in the same fiber with the classical data channel, but uses a completely independent modulation and detection mechanism.

The system supports docking with external quantum key generation devices to achieve key distribution based on quantum mechanics principles, with a key generation rate of up to 10Mbps, which is sufficient to meet the real-time encryption requirements of all data channels.The encryption mechanism adopts a hybrid encryption system combining One Time Password (OTP) and Advanced Encryption Standard (AES-256), which ensures both theoretical absolute security and practical efficiency.

In terms of trusted transmission, the board hardware integrates chip fingerprint technology based on PUF (physically unclonable function), and each board has a globally unique hardware identifier to prevent device counterfeiting and tampering.During the data transmission process, blockchain based transmission logging is used, and all operations have tamper proof audit trails.

The software licensing adopts a capacity based floating license model, where customers pay based on the actual transmission capacity used, without the need to purchase a fixed specification license in advance.The system supports automated license allocation and retrieval, and license resources can be dynamically adjusted across the entire network when business needs change.

The synchronization system requires extremely high requirements and must be equipped with cesium atomic clock or hydrogen maser clock as the primary clock source, with frequency stability better than 1E-13 and time synchronization accuracy reaching nanosecond level.The synchronization signal is transmitted through a dedicated optical synchronization channel, which is on the same fiber as the data channel but with different waves, reducing delay jitter.

5.Typical application scenarios and configurations

International submarine cables and intercontinental backbone

In the international submarine cable system, TNV3T220 adopts DP-QPSK modulation to ensure relay free transmission for thousands of kilometers. In response to the special environment of submarine optical cables, the working mode of the board is adjusted to: reduce transmission power to reduce nonlinear effects, enhance FEC redundancy to cope with difficulties in underwater repair, and enable full performance monitoring to warn potential faults in advance.

Multi layer protection mechanism for system configuration: Firstly, each 600G channel's three subcarriers use different routes and transmit through different fiber cores of the submarine cable;Secondly, the submarine cables in the east-west direction form a ring network protection, and any point of breakage can be restored through reverse routing;Finally, important businesses also configure satellite links as the final backup.Protection switching time requirements: subcarrier level protection<50ms, fiber level protection<200ms, submarine cable level protection<2s, satellite backup switching<10s.

6G Research Experiment Network

In the 6G experimental network, TNV3T220 serves as the carrier platform for terahertz wireless transmission.Each 600G channel carries baseband data from multiple terahertz wireless cells, using CPRI over Ethernet encapsulation format with extremely strict latency requirements.The system configuration is based on the Time Aware Shaping (TAS) mechanism of IEEE 802.1Qbv, which reserves a fixed time window for wireless synchronization signals to ensure that the time synchronization accuracy of the wireless air interface reaches 100ns level.

The network supports dynamic collaborative scheduling of wireless and optical network resources.When the business volume of a terahertz cell surges, the optical network automatically adjusts the slice bandwidth corresponding to that cell;When the wireless channel conditions change, the modulation format and FEC configuration of the optical network are adjusted accordingly, forming a wireless optical joint optimization.This cross layer optimization improves overall spectrum efficiency by over 50%.

The experimental network also explored a new architecture for optical wireless fusion, which directly converts optical signals into terahertz wireless signals at the base station side, omitting the intermediate electrical signal conversion step.This type of photoelectric direct conversion reduces end-to-end latency from microseconds to nanoseconds, laying the foundation for the ultimate low latency application of 6G.

The self-healing system is divided into three levels: device level self-healing is achieved through the built-in BIST (built-in self-test) circuit of the chip, which monitors and corrects internal parameter drift in real time;Board level self-healing automatically restores performance degradation by reconfiguring DSP parameters, switching backup circuits, adjusting working modes, and other methods;Network level self-healing uses SDN controllers to automatically calculate and establish alternative routes when link failures are detected.

Preventive maintenance is based on remaining useful life (RUL) prediction.The system predicts the remaining life of each device by monitoring the growth rate of laser threshold current, ESR changes of capacitor devices, vibration spectrum of cooling fans, etc.The maintenance plan is dynamically adjusted based on the predicted results, achieving a transition from regular maintenance to on-demand maintenance.
