10/100TX-FX Single Fiber Industrial Media Converter | 1-RJ45 Ethernet Port, 1-ST Fiber Port

Industrial 10/100Mbps Ethernet-to-Fiber Conversion

The MF7275-2SFA provides dependable copper-to-fiber conversion for industrial Ethernet networks. It features one 10/100Mbps RJ45 copper port and one 100Mbps ST fiber port, allowing Ethernet devices to communicate over single-mode fiber while extending network reach beyond the limitations of standard copper cabling.

The converter uses a non-blocking store-and-forward switching architecture for efficient packet processing and supports a 2K MAC address table with frame sizes up to 1536 bytes.

Single-Fiber Connectivity Over 20km

The MF7275-2SFA is designed for applications where only one strand of single-mode fiber is available.

Using wavelength-division multiplexing, the converter transmits and receives data over the same fiber strand. The MF7275-2SFA uses 1310nm for transmission and 1550nm for reception and is paired with the MF7275-2SFB, which uses the reverse wavelength configuration. Both models support transmission distances up to 20km.

This single-fiber configuration can help:

• Extend Ethernet networks over existing fiber infrastructure
• Connect remote industrial equipment
• Reduce the number of fiber strands required
• Connect facilities where fiber availability is limited
• Extend surveillance and control networks over long distances

Reliable Ethernet Performance

The MF7275-2SFA's RJ45 copper port supports 10/100Mbps auto-negotiation and auto MDI/MDI-X, simplifying installation with a variety of Ethernet devices. It supports both full- and half-duplex operation.

Flow control includes IEEE 802.3x pause frames for full-duplex operation and back pressure for half-duplex operation, helping maintain reliable data transmission during periods of increased network traffic.

Built for Harsh Industrial Environments

Unlike standard commercial media converters, the MF7275-2SFA is designed for industrial installations where temperature, electrical interference, and power reliability can be concerns.

The converter features:

• Dual 9–52VDC power inputs for redundant power
• 4KV Ethernet surge protection
• IP44 metal housing
• DIN rail mounting
• -40°C to +80°C operating temperature
• Greater than 100,000-hour MTBF
• Industrial-rated emission and immunity performance

These features make the MF7275-2SFA well suited for control cabinets, industrial equipment rooms, transportation infrastructure, and other demanding network environments.

Easy Installation and Network Monitoring

The MF7275-2SFA is designed for straightforward installation and network troubleshooting. LED indicators provide local visibility into power, copper link/activity, and fiber link/activity status.

The RJ45 interface automatically detects connected Ethernet devices and cable configuration, reducing the need for manual network setup.

Its compact industrial enclosure and DIN rail mounting make it suitable for installation inside control panels and network cabinets where space is limited.

20km Single-Mode Fiber Transmission

The MF7275-2SFA provides a 20km single-mode fiber connection using an ST connector. Its wavelength configuration is specifically designed to work with the complementary MF7275-2SFB.

The MF727x datasheet identifies the MF7275-2SFA specifically as the SM, ST, 20km single-fiber model with 1310nm TX and 1550nm RX.

Typical Applications

The MF7275-2SFA is well suited for industrial networks that require reliable Ethernet connectivity over long-distance single-mode fiber.

• Industrial automation and control
• IP camera and video surveillance networks
• Intelligent transportation systems
• Traffic monitoring and control
• Oil and gas facilities
• Mining operations
• Power and utility networks
• Factory and manufacturing networks
• Remote monitoring and control
• Industrial security systems
• Networks with limited fiber availability

Why Choose the MF7275-2SFA?

The MF7275-2SFA combines long-distance single-fiber connectivity with the rugged construction required for industrial network deployments. Its 20km single-mode fiber capability, ST connector, redundant DC power, 4KV surge protection, DIN rail mounting, and -40°C to +80°C operating temperature make it a strong choice for extending Ethernet into demanding environments.

For single-fiber communication, the MF7275-2SFA is paired with the complementary MF7275-2SFB, which uses the opposite transmit and receive wavelengths.
