Product Performance

The data transmission delay of Ethernet ports is ≤1ms (1000Mbps full-duplex mode), and the data conversion delay between VMEbus and Ethernet is ≤2ms, meeting the low-latency requirements of industrial real-time control. It supports STP/RSTP network redundancy protocol, with dual-port fault switching time ≤50ms, ensuring uninterrupted data transmission when the network is interrupted.

Gigabit bandwidth supports concurrent transmission of large-flow data (e.g., real-time data aggregation of multi-channel sensors), with a maximum throughput of ≥900Mbps per port (TCP protocol). The combination of optical isolation design and anti-EMC performance ensures a data transmission bit error rate of ≤1×10⁻¹² under 2.5kV AC isolation voltage and strong RF environment, guaranteeing signal integrity.

The module is compatible with VME master controllers and industrial Ethernet devices from different manufacturers, supporting online firmware upgrade (no module disassembly required), and the upgrade process does not interrupt data transmission. The Mean Time Between Failures (MTBF) is ≥800,000 hours (MIL-HDBK-217F, 25℃ environment), adapting to 24/7 continuous production scenarios.
