1000BASE-T Copper SFP Industrial Module: 1000M-SFP-MI

Our EDGEOPTIC 1000M-SFP-MI is a multi-vendor compatible 1000BASE-T copper SFP module designed to enable SFP-equipped networking devices to connect via standard copper twisted pair cabling for dedicated Gigabit Ethernet applications in demanding industrial environments. This industrial-grade copper transceiver provides a robust solution for short-reach high-speed connectivity in manufacturing facilities, outdoor installations, transportation systems, and harsh environment deployments where extended temperature operation is essential.

The 1000M-SFP-MI module operates at a fixed 1000 Mbps Gigabit Ethernet rate over standard Category 5 or better twisted pair cabling. Unlike tri-speed copper SFP modules that support auto-negotiation across multiple speeds, this Gigabit-only variant is optimized for environments where all connected devices operate at 1000BASE-T, providing streamlined operation without lower-speed fallback. The module features an integrated RJ45 connector providing direct copper connectivity without requiring external media converters or additional cabling adapters. Transmission distances reach up to 100 meters over Category 5 or better unshielded twisted pair (UTP) cabling, consistent with IEEE 802.3ab Gigabit Ethernet distance specifications for copper media.

The 1000M-SFP-MI is a hot-pluggable SFP module featuring an RJ45 electrical interface. The host-side electrical interface conforms to INF-8074i and SFP MSA (Multi-Source Agreement) specifications, ensuring compatibility with standard SFP host systems across multiple vendor equipment platforms. Our industrial copper SFP transceiver can be encoded for compatibility with 80+ equipment brands, enabling seamless integration into existing network infrastructure. The module incorporates DDM/DOM (Digital Diagnostic Monitoring) functionality where supported by the host equipment, providing real-time operational parameters for comprehensive monitoring of transceiver health and performance – particularly valuable in remote industrial installations where proactive maintenance reduces costly site visits.

The industrial-grade design operates across an extended temperature range of -45°C to +85°C, enabling reliable deployment in environments where standard commercial-grade transceivers would fail. This includes outdoor telecommunications cabinets, roadside traffic management systems, railway trackside equipment, oil and gas installations, mining operations, cold storage facilities, and manufacturing environments with significant temperature variations. The ruggedized construction ensures consistent performance across extreme temperature cycles without degradation. Gigabit-only copper SFP modules provide particular value in homogeneous Gigabit industrial environments where all endpoint devices support 1000BASE-T, and the fixed-speed design can offer advantages where speed negotiation overhead is undesirable. The SFP form factor, while considered a legacy standard, remains widely deployed across industrial networks due to its proven reliability. Power requirements are met by a single +3.3V supply.

Standards compliance includes IEEE 802.3ab for 1000BASE-T Gigabit Ethernet operation. The transceiver achieves multi-vendor interoperability through adherence to industry MSA standards, though equipment with vendor-specific module validation may require custom EEPROM programming for full compatibility. Our industrial copper SFP transceiver is CE and RoHS certified.

Typical applications include industrial automation and SCADA systems requiring dedicated Gigabit connectivity, railway and transportation networks, outdoor telecommunications infrastructure, smart grid deployments, industrial Ethernet backbones, and any harsh environment requiring SFP-slot fixed Gigabit copper connectivity with extended temperature operation. Because our focus is providing top quality service, we perform rigorous quality checks before delivery. This includes electrical parameter testing across the full temperature range, connector inspection, and SFP transceiver EEPROM memory data validation tests.
