Huawei adds AI computing power optical module

Huawei adds AI computing power optical module

In the AI era, Huawei provides a full range of GE to 800GE optical modules, featuring three major capabilities: Spanning (ultra-long transmission), Stable (ultra-high reliability), and Secure (ultra-solid security). To address these demands, Huawei has launched the StarryLink optical module brand. LRO (linear receiver optics) optical module is a pluggable optical module that retains a re timer at the. On April 24, 2025, during the Energy Network Communication Innovation Application Conference, Yang Xi, President of Huawei's Government and Enterprise Optical Division, delivered a keynote speech titled "No Light, No AI – Full Optical Networks Accelerate AI Empowerment in New Power Systems. The Huawei CloudMatrix 384 super-node is a key technological breakthrough of Huawei AI computing infrastructure, mainly used to solve the communication efficiency problem of large-scale AI clusters. Imagine connecting thousands of powerful AI chips scattered in dozens of server cabinets and making them work together as if they were a single, massive computer.

High-precision optoelectronic fusion for rail transit applications

High-precision optoelectronic fusion for rail transit applications

This paper proposes a real-time fusion algorithm of Ultra-Wideband (UWB) and Inertial Measurement Unit (IMU) information based on the Error-State Kalman Filter (ESKF) algorithm, aiming to achieve high-precision train positioning throughout the entire railway, particularly in tunnel. Moreover, accurate localization paves the way for a variety of advanced key applications such as Automated Train Operation (ATO), making it a prereq npoint posi-tioning at all times. Three core improvements were integrated: 1) AVCStem module with variable convolution kernels to dynamically adapt to defects of different shapes and scales; 2) ADSPPF module using multi-scale pooling and multi-branch attention mechanisms to preserve fine-grained features across scales; 3) MSF.

Fiber Optic Rail Transit

Fiber Optic Rail Transit

Rail transit fiber infrastructure demonstrates strong growth in 2025, driven by digital transformation and urban expansion. Operators deploy fiber broadband and advanced fiber optics to address vibration resistance and signaling reliability. A single pair of fiber cores, the technology enabling the running of 1000BASE (i. , 10 Gbit/s data rate) operations today, could comfortably scale up to 40GBASE or even 100GBASE operations in the future without requiring any change of cabling. Fiber optic cables will be laid along the railway lines and new antenna sites will be installed for future railway radio systems for the real-time transmission of large volumes of data.

What is an AI computing power cloud server

What is an AI computing power cloud server

cloud-based ai servers: these are virtual servers hosted by cloud providers like amazon web services (aws), google cloud platform (gcp), and microsoft azure. they offer scalability, flexibility, and reduced infrastructure costs but rely on an internet connection and may raise data. AI, or artificial intelligence, is changing the way organizations and businesses handle data by incorporating automation of complex calculations, introducing new advanced applications, and fulfilling computational demands like never before. AI servers are high-performance computing systems designed to process complex artificial intelligence workloads, including large-scale model training and real-time inference. It has advanced compute, network and storage architectures and energy and cooling capabilities to handle AI workloads.
