Key Functions

Long-distance Fiber Ethernet Data Transmission Converts electrical Ethernet signals into optical fiber signals for substation equipment, completely eliminating severe electromagnetic interference (EMI) in power plants. It solves EMC interference and insulation defects of copper Ethernet cables and extends communication distance significantly.
Full Compatibility with Power Industry Standard Protocols Natively supports the complete IEC 61850 suite for power systems: MMS for SCADA monitoring, GOOSE for high-speed protection trip signals, SV / IEC 61850-9-2 for merging unit sampled values. It is also compatible with Modbus TCP, IEC 60870-5-104, DNP3, PROFINET IO, IEEE C37.118 synchrophasor PMU protocol, and DIGSI 5 commissioning protocol.
Support for Redundant Substation Network Architecture Compatible with industrial redundancy protocols including HSR (High-availability Seamless Redundancy), PRP (Parallel Redundancy Protocol), and RSTP. It builds non-interrupt redundant communication networks to meet uninterrupted communication requirements of power protection relays.
High-precision Time Synchronization Hardware-based IEEE 1588 PTP precise time synchronization, SNTP server & client functions. It provides microsecond-level time sync for all station protection, measurement, and fault recording devices to ensure accurate fault sequence logging.
Dedicated Process Bus Adaptation Designed for Merging Units (MU) and bay-level protection relays. It stably transmits high-frequency SV sampled value streams and millisecond-level GOOSE trip signals to realize fiber interconnection between primary equipment and secondary protection devices in digital substations.
Remote Commissioning & Equipment Maintenance Enables remote parameter configuration, fault record retrieval, online diagnosis, and firmware upgrade of protection relays via fiber links using DIGSI 5 software.

2. Main Applications

Digital Smart Substations (Core Application) Communication expansion for bay-level protection relays (line protection, transformer protection, busbar protection, capacitor bank protection); connects primary-side Merging Units to transmit SV sampled value data and GOOSE protection trip signals.
Anti-interference Networking for EHV/UHV Substations Substations suffer from strong electromagnetic pulses generated by circuit breakers, disconnectors and lightning strikes. Optical fiber has no conductive loop to avoid communication outages caused by surge and EMI, ensuring reliable transmission of protection signals.
Long-distance Cross-bay Equipment Communication Multi-mode fiber supports transmission up to 2 km, meeting long-distance wiring demands between high-voltage switchyards and local control cabinets.
Construction of Redundant Secure Power Ring Networks Build dual-network redundant architecture based on HSR/PRP protocols. Zero-latency switchover occurs upon single fiber link failure to prevent protection malfunction or failure to trip, complying with power safety codes.
Protection & Control for Power Plants, PV / Wind Energy Storage Power Stations Support generator protection, box transformer measurement & control, energy storage PCS paired with SIPROTEC 5 devices; fiber networking enables remote monitoring and rapid fault isolation.
Traction Substations for Rail Transit & Metallurgical Industrial Power Stations Replaces copper Ethernet cables in industrial power scenarios with heavy harmonics and large load currents to improve communication stability.
