Product Features
Technical Overview
This media converter operates as a transparent bridge between copper RJ-45 interfaces and multi-mode fiber optic connections. It implements full-duplex Fast Ethernet technology with automatic speed and duplex negotiation on the copper side, while the fiber interface maintains consistent 100Base-FX operation for reliable optical transmission.
The device supports standard twisted pair cabling (Category 5e or higher recommended) alongside 62.5/125μm or 50/125μm multi-mode fiber with ST connectors. No configuration is required for basic operation—the converter automatically detects and adapts to network conditions while maintaining signal integrity across the media transition.
Key Product Advantages
This converter eliminates compatibility barriers between copper and fiber network segments, enabling cost-effective infrastructure expansion without replacing existing equipment. Its transparent operation ensures minimal latency while maintaining full Fast Ethernet performance across both media types.
Media Flexibility
Simultaneously supports twisted pair copper cabling and multi-mode fiber optics, allowing mixed-media network designs that leverage the strengths of both transmission technologies.
- Uses standard RJ-45 connectors for copper
- Accepts ST connectors for fiber
- No media-specific configuration required
Reliable Performance
Delivers consistent 100Mbps throughput with automatic speed and duplex negotiation, ensuring optimal data transfer rates without manual intervention.
- Full-duplex operation
- Automatic MDI/MDIX crossover
- Signal regeneration between media
Deployment / Use Cases
The AP-FXE-ST-01 is ideal for extending copper-based network segments over fiber optic cabling in environments where electrical isolation, longer distances, or EMI resistance are required. Its compact form factor and simple operation make it suitable for both permanent installations and temporary network expansions.
Common applications include connecting copper switches to fiber backbone links, extending network reach beyond copper distance limitations, implementing fiber links in electrically noisy industrial settings, and creating isolated network segments for security or testing purposes. The converter's plug-and-play design minimizes setup time while its compliance with environmental regulations ensures suitability for regulated facilities.
Distance Extension
Overcome the 100-meter limitation of copper Ethernet by converting to multi-mode fiber, which supports distances up to 2 kilometers depending on fiber grade and transceiver characteristics.
EMI Protection
Fiber optic segments provide complete electrical isolation, eliminating ground loop issues and protecting equipment from electrical surges in industrial or outdoor installations.

FAQ
What does this media converter actually convert between?
The Lantronix AP-FXE-ST-01 converts network signals between copper twisted pair cabling (using RJ-45 connectors) and multi-mode fiber optic cabling (using ST connectors). It translates electrical signals from copper interfaces to optical signals for fiber transmission, and vice versa, enabling seamless communication between these different media types within a Fast Ethernet network.
What type of fiber optic cable does this converter support?
This converter supports multi-mode fiber optic cables with ST connectors. It is compatible with standard 62.5/125μm and 50/125μm multi-mode fiber types commonly used in enterprise and industrial networking applications. The device does not support single-mode fiber, which requires different optical characteristics and is typically used for longer distance applications.
What network speeds does this media converter support?
The converter supports Fast Ethernet speeds up to 100Mbps. On the copper side, it automatically negotiates between 10Base-T and 100Base-TX operation based on the connected equipment. On the fiber side, it operates at a fixed 100Base-FX rate. This makes it suitable for integrating legacy 10Mbps equipment with modern 100Mbps networks while maintaining optimal performance across the media conversion.
Does this converter require any configuration or setup?
No configuration is required for basic operation. The Lantronix AP-FXE-ST-01 is designed as a plug-and-play device that automatically handles speed negotiation, duplex settings, and signal conversion between media types. Simply connect the appropriate cables to the RJ-45 and ST ports, apply power, and the converter begins operating immediately without any user intervention or software configuration.
