Deployment of Communication Networks for Urban Rail Transit

Provides communication networks for subway signaling systems to ensure safe train operations.

Project Background

Urban rail transit signaling systems require a high-reliability dedicated communication network. Equipment must be EN50121-3 railway electromagnetic compatibility certified to withstand the intense electromagnetic interference generated during train operation.

Solution

Deploy IS7400 series industrial switches at stations and track sections along the line, connecting all sites via an ERPS ring network to ensure high-reliability signal data transmission. The devices are certified for railway EMC and support operation in a wide temperature range of -40°C to 75°C.
