INTELLIGENT TECHNOLOGIES IN HIGH SPEED RAIL TRANSIT SYSTEMS

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.

Customization Process for Hot-Selling Reconfigurable Optical Add-Drop Multiplexers for Rail Transit

Network operators diversify service offerings and enhance network efficiency by leveraging bandwidth-variable transceivers and colorless flexible-grid reconfigurable optical add-drop multiplexers (RO.

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.

Intelligent Computing Center Uses Hollow-Core Fiber for High Precision

UCF researchers have developed a hollow-core fiber that transmits data nearly 50% faster, setting the stage for the next generation of AI-powered infrastructure. Unlike traditional fibre-optic cables, which rely on solid glass cores, HCF features an air-filled core supported by precision-engineered anti-resonant structures. For field deployment, EXFO's Hollow Core Fiber OTDR analysis software, part of a Hollow Core Fiber OTDR Test Kit, provides accurate fault location and loss measurements where traditional OTDRs fall short. Here's what network engineers and CCIE candidates need to know about HCF in 2026. As the AI race continues to heat up, hollow core fiber (HCF) has emerged as a potential alternative to single-mode optical fiber (SMF). Held in San Francisco, California, this year's OFC attracted 16,700 attendees from 83.
