The GIGAC 0–50Mbps Low-Speed Industrial Control Dual-Fiber SFP Optical Module (Series DTACS/DT-57B4) is a high-reliability fiber optic transceiver engineered for industrial automation, process control, and critical communication infrastructure. Housed in a standard SFP form factor with LC duplex connectors, it integrates VCSEL laser transmitters and PIN photodetectors to deliver noise-immune, long-distance data transmission across single-mode and multimode fiber.

Unlike conventional SFP modules designed for IT networks, this transceiver is purpose-built for industrial sites characterized by strong electromagnetic interference, mechanical vibration, extreme temperatures, and requirements for continuous uptime. The module supports adaptive data rates from DC to 50Mbps, enabling backward-compatible integration with legacy SCADA, PLC, and serial control systems.

 Key Features：

•        Support rates: 0–2Mbps, 0–10Mbps, 0–20Mbps, DC–50Mbps adaptive

•        SFP package with LC duplex (dual-fiber) connector•        VCSEL laser transmitter and PIN photodetector

•        Digital Diagnostic Monitoring Interface (DDMI) compliant with SFF-8472

•        Supports 50/125μm and 62.5/125μm MMF fiber transmission

•        3.3V power supply; LVTTL logic level / CML logic level compatible

•        Extremely low electromagnetic interference (EMI) and superior ESD protection

•        Wide operating temperature: -40°C to +85°C (extended: -55°C to +85°C per model)

•        Metal housing for efficient heat dissipation

•        Typical power consumption: ≤0.8W

Technical Advantages：

Industrial-Grade Reliability

The module uses a dual-fiber bidirectional architecture with physically isolated TX/RX channels, which significantly reduces co-frequency interference compared to single-fiber BiDi designs. This separation is critical in environments with dense cabling and multiple concurrent signal channels.

Anti-Interference & Certified EMC Performance

Tested and certified to IEC 61373 vibration and shock standards, and EMC Class 4 — the highest industrial electromagnetic compatibility classification. The metal shell acts both as a thermal dissipator and an RF shield, protecting signal integrity in high-noise environments such as motor drive cabinets and switchgear rooms.

Extended Temperature Operation

With a wide industrial temperature range of -40°C to +85°C (or -55°C to +85°C for select models), and IP40-rated protection against particulate ingress, this module maintains stable optical performance in outdoor switchgear, rail-side cabinets, and chemical processing environments.

Protocol Interoperability

The module supports 0–20Mbps rate adaptation and is fully compatible with mainstream industrial protocols including Modbus RTU/ASCII, Modbus TCP, and PROFINET IO. This ensures plug-and-play connectivity with PLCs, SCADA systems, DCS controllers, and RTUs from major vendors.

Long Service Life

With a Mean Time Between Failures (MTBF) exceeding 200,000 hours and domestically produced optical components, the module offers a cost-effective, long-lifecycle solution for critical infrastructure where maintenance downtime is costly.

Typical Applications：

•        Smart factory equipment networking and industrial Ethernet backbone

•        Rail transit signal control and trackside communication systems

•        Power distribution network automation and substation control

•        RS232 / RS485 / RS422 serial-to-fiber converters

•        Modbus RTU and PROFINET field device connections

•        SCADA and PLC remote I/O over fiber

•        Building automation and intelligent transportation systems

•        Oil & gas facility instrumentation networks

Compatibility & Industrial Deployment：

The GIGAC industrial SFP series is compatible with standard SFP slots in industrial Ethernet switches, media converters, and serial device servers. The digital diagnostic monitoring interface (per SFF-8472) enables real-time monitoring of optical power, temperature, voltage, and bias current, facilitating predictive maintenance in managed network deployments.

The module is fully interoperable with fiber from leading vendors including Corning, Prysmian, and OFS, using standard LC-PC and LC-APC connectors. For custom wavelength requirements (1310nm / 1550nm / 850nm) or extended temperature variants, contact our engineering team for configuration support.
