Product Features
Technical Overview
This media converter operates at Fast Ethernet speeds (100 Mbps) and supports both 100Base-TX over twisted pair and 100Base-X over fiber optic media. The fiber interface uses multi-mode technology with Duplex SC connectors, optimized for 850 nm wavelength transmission. The internal autosensing power supply accepts a wide range of input voltages, reducing compatibility concerns with local power sources.
Link fault detection capabilities monitor both copper and fiber segments, providing immediate visual alerts through diagnostic LEDs when connectivity issues occur. This enables rapid isolation of breaks or problems, minimizing network downtime during troubleshooting.
This section brings together practical product details such as Total Number of Ports, Network (RJ-45), Number of Network (RJ-45) Ports, Media Type Supported, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

- No manual crossover configuration required
- Self-adjusting for straight-through or crossover cables
Enhanced Diagnostics
Link fault detection features monitor both copper and fiber segments, with diagnostic LEDs that visually indicate the location and type of connectivity issues for faster troubleshooting.
- Visual fault indication per port
- Quick isolation of copper or fiber segment problems
Deployment / Use Cases
This media converter is ideal for extending Fast Ethernet networks beyond the 100-meter limitation of copper cabling, particularly in environments where fiber optic infrastructure is already deployed or planned. Common applications include connecting buildings across campus, linking network equipment in industrial settings with electromagnetic interference concerns, or integrating fiber backbone segments with copper-based edge devices.
The compact form factor and simple power requirements make it suitable for deployment in telecom closets, equipment racks, or desktop locations where space is limited. The device supports standard office environments as well as industrial applications that benefit from fiber's immunity to electrical noise and longer distance capabilities.
Building-to-Building Connectivity
Extend network connections between separate buildings using existing fiber optic runs while maintaining compatibility with copper-based network equipment at each endpoint.
EMI-Prone Environments
Replace copper runs in manufacturing floors, utility rooms, or other areas with significant electromagnetic interference where fiber optic immunity provides more reliable connectivity.

User Manual
FAQ
What does this media converter actually convert?
This Black Box media converter converts Fast Ethernet signals between two media types: it takes 100Base-TX signals from copper twisted pair (via the RJ45 port) and converts them to 100Base-X signals for transmission over multi-mode fiber optic cable (via the Duplex SC port), or vice versa. This allows network segments using different physical media to communicate seamlessly at Fast Ethernet speeds.
What type of fiber optic cable and connectors does this converter support?
The converter supports multi-mode fiber optic cable with Duplex SC connectors. It's optimized for 850 nm wavelength transmission, which is standard for many multi-mode fiber installations. The device has one dedicated Duplex SC port that accepts industry-standard SC connectors commonly used in enterprise and campus network environments.
What is the maximum distance this converter can support between network devices?
This media converter supports fiber optic connections up to 0.30 kilometers (approximately 0.19 miles or 300 meters). This distance represents the maximum recommended span between the converter and the connected fiber optic device when using multi-mode fiber at 850 nm wavelength. The actual achievable distance may vary slightly based on fiber quality and environmental conditions.
How does the automatic crossover/passthrough function work?
The automatic crossover/passthrough function on the RJ45 port detects whether the connected copper cable is straight-through or crossover configuration and automatically adjusts the internal termination accordingly. This eliminates the need for manual configuration or special cables during installation—the converter figures out the correct pinout automatically, simplifying deployment in various network scenarios.
What diagnostic capabilities does this media converter provide?
The converter includes link fault detection features that monitor both the copper and fiber segments for connectivity issues. When faults occur, diagnostic LEDs on each port provide visual alerts indicating the location (copper port or fiber port) and type of problem. This enables network administrators to quickly isolate whether issues originate in the copper segment, fiber segment, or specific port connections.
What power requirements does this converter have?
The converter uses an internal autosensing power supply that accepts a wide range of input voltages, typically accommodating common power standards across different regions. This design reduces compatibility concerns with local power sources and eliminates the need for external voltage selection or configuration. The power supply is integrated into the compact unit design.
