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

Reliable 10/100Mbps Copper-to-Fiber Conversion

The VERSITRON MF7273 Industrial Media Converter provides a reliable way to connect 10/100Mbps Ethernet equipment to a multimode fiber optic network. Its RJ45 copper port supports 10/100Mbps Ethernet, while the 100Mbps fiber interface extends network connectivity over multimode fiber.

The MF7273 uses a non-blocking store-and-forward switching architecture with a 0.4Gbps switching capacity and a 2K MAC address table. It supports frame sizes up to 1536 bytes and provides back-pressure for half-duplex operation and IEEE 802.3x pause-frame flow control for full-duplex communication.

2km Multimode Fiber Connectivity with ST

The MF7273 is specifically configured with a 100Mbps multimode fiber port and ST connector, supporting fiber transmission distances of up to 2 kilometers. The MF727x product datasheet identifies the MF7273 as the MM/ST/2km model operating at a 1310nm wavelength.

This makes the MF7273 a practical choice when an existing network uses ST-terminated multimode fiber and needs to be integrated with modern 10/100Mbps Ethernet equipment.

Designed for Industrial Network Installations

The MF7273 is built with features intended to improve reliability in demanding environments. Its redundant DC power inputs, surge protection, rugged metal enclosure, and extended temperature range provide additional protection and installation flexibility.

The converter supports:

• Dual 9–52VDC power inputs with auto-sensing
• 4KV Ethernet surge protection
• IP44 metal enclosure
• DIN rail mounting
• -40°C to +80°C operating temperature
• 4W full-load power consumption
• MTBF greater than 100,000 hours
• 0–95% relative humidity, non-condensing

These characteristics make the MF7273 well suited for industrial control cabinets, transportation systems, security installations, and other locations where network equipment may be exposed to temperature extremes or electrical interference.

Easy Integration with Existing Ethernet Networks

The MF7273 supports 10/100Mbps auto-negotiation and auto MDI/MDI-X crossover on its RJ45 copper port. This allows the converter to automatically adapt to connected Ethernet equipment and simplifies installation.

Full-duplex and half-duplex operation are supported, while LED indicators provide local status information for power, copper link/activity, and fiber link/activity.

Typical Applications

The MF7273 can be used in networks that require 10/100Mbps Ethernet connectivity over multimode ST fiber, including:

• Industrial Automation – Connect Ethernet-enabled machinery, controllers, and other equipment over fiber.
• IP Surveillance Networks – Extend connectivity to network cameras and security equipment.
• Industrial Security Systems – Connect access control, intercom, and monitoring equipment.
• Intelligent Transportation Systems – Provide fiber connectivity between field equipment and centralized network infrastructure.
• Manufacturing Facilities – Extend Ethernet connections between production areas and network equipment.
• Remote Equipment Connectivity – Connect Ethernet devices located beyond the practical reach of copper cabling.
• Copper-to-Fiber Network Expansion – Integrate existing copper Ethernet equipment into a multimode fiber network.

MF727x Industrial Media Converter Family

The MF7273 is part of the VERSITRON MF727x Industrial Media Converter family, which provides multiple fiber configurations for different connector types, fiber types, and transmission distances.

The product family documentation specifically identifies the MF7273 as the MM/ST/2km model and the MF7274 as the corresponding MM/SC/2km model.

Why Choose VERSITRON?

The MF7273 combines straightforward 10/100Mbps Ethernet-to-fiber conversion with the industrial features needed for reliable network deployment. Redundant DC power, 4KV Ethernet surge protection, rugged IP44 metal construction, DIN rail mounting, and an extended operating temperature range make it a strong choice for demanding installations.

The MF727x family also gives network designers the flexibility to select a converter based on fiber type, connector, and transmission distance, allowing the converter to match the requirements of the existing fiber infrastructure rather than requiring unnecessary network changes.
