1. Product Overview

TNU5N401 is an industry-leading single wave 800G high-performance coherent wavelength division multiplexing circuit board launched by Huawei for the next generation of optical transmission networks, specifically designed for the Huawei OSN 9800 U64 optical transmission platform.This board integrates Huawei's latest generation oDSP (Optical Digital Signal Processor) chip and advanced optoelectronic technology, aiming to address the exponential bandwidth growth challenges faced by data center interconnect (DCI), computing power networks, 5.5G/6G carriers, and backbone network core layers.It is a strategic component for building ultra large capacity, ultra-low latency, and ultra-high efficiency all-optical bases.

2.Core Features and Technological Innovation

Single wave 800G industry benchmark speed

Supporting a single channel transmission rate of 800Gbps on the line side, it is one of the highest speed levels currently available for commercial mass-produced products, maximizing single fiber capacity and significantly reducing transmission costs and power consumption per bit.

Support adjustable speed, based on actual transmission distance and fiber conditions, software configuration includes multiple modes such as 800G, 600G, 400G, 200G, etc., achieving flexible deployment and optimal performance.

Ultra high performance coherent transmission engine

Equipped with Huawei's self-developed 7nm/5nm high-performance oDSP chip, it has industry-leading signal processing capabilities and energy efficiency.

Supports ultra-high order and programmable modulation formats, including but not limited to 128QAM, 64QAM, 32QAM, and 16QAM, combined with enhanced probability constellation shaping (PCS+) technology, approaching the Shannon limit and achieving the ultimate improvement in spectral efficiency.

Having excellent nonlinear compensation and damage tolerance capabilities, ensuring stable transmission in complex long-distance, multi span links.

Full scene adaptation for computing power networks

Deep optimization supports all-optical crossover (OXC) networking, meeting the dynamic, flexible, and low latency scheduling requirements between computing power centers.

Supporting hard slicing technologies such as FlexE (Flexible Ethernet) and OSUflex (Flexible Optical Service Unit), it can provide deterministic bandwidth and isolation channels for AI computing, supercomputing, autonomous driving, and other businesses.

Perfectly supporting high-speed Ethernet services such as 800GE, 400GE, and 200GE, it is an ideal choice for High Speed Data Center Interconnection (HDCI).

C+L band extension and intelligence

Design support for extended C+L band operation, providing over 48Tbps of ultra large capacity on a single fiber, meeting bandwidth needs for over the next decade.

Built in intelligent digital twin engine can achieve performance prediction, fault self-healing, and parameter tuning of the optical layer, greatly improving the level of operation and maintenance automation.
