Product Features
Technical Overview
The C3221-1040 operates at Layer 2, providing transparent conversion between 1000Base-T over twisted pair and 1000Base-X over fiber. It supports full-duplex Gigabit Ethernet with a maximum data transfer rate of 1000 Mbit/s, ensuring no bottleneck in high-speed network segments. The device handles jumbo frames up to 9KB, optimizing throughput for large data packets common in storage or video streaming scenarios.
Built with auto-MDI/MDIX on the RJ-45 port, it eliminates the need for crossover cables, simplifying installation. The SFP slot is hot-swappable, allowing module changes without powering down the unit. Internal diagnostics include link and activity LEDs for both copper and fiber interfaces, providing clear status indication for quick troubleshooting.
Key Product Advantages
This media converter simplifies network upgrades by allowing incremental fiber deployment without replacing entire copper infrastructures. Its small footprint and versatile mounting options make it suitable for space-constrained environments like wiring closets or equipment racks.
Media Flexibility
Supports both twisted pair and optical fiber, enabling conversion between copper and fiber segments to extend network reach or isolate electrical noise.
- Choose SFP modules for LC, SC, or other connectors
- Use with Cat5e/6/6a copper cabling
Deployment Simplicity
Plug-and-play operation with no configuration required, reducing installation time and technical overhead for network expansions or fiber migrations.
- Auto-negotiates speed and duplex on RJ-45 port
- LED indicators for quick link status verification
Deployment / Use Cases
The ION C3221-1040 is ideal for extending network segments beyond the 100-meter limit of copper cabling by converting to fiber optic runs. It connects fiber backbone links to copper-based edge devices like switches, routers, or servers in mixed-media environments.
Common applications include connecting buildings across campuses where fiber is already installed, integrating fiber-optic security cameras into copper networks, or linking industrial equipment in noisy electrical environments where fiber provides immunity to interference. In data centers, it facilitates connections between copper switches and fiber storage arrays or uplinks.
Campus Network Extension
Extend Gigabit Ethernet between buildings using existing fiber infrastructure while maintaining copper connectivity at each endpoint for device compatibility.
Industrial Networking
Deploy in manufacturing or utility settings where fiber's noise immunity ensures reliable data transmission between control systems and field devices over longer distances.

User Manual
FAQ
What types of media does this converter support?
The Transition Networks ION C3221-1040 supports both twisted pair copper cabling (like Cat5e, Cat6) and optical fiber. It converts signals between these media types, allowing you to connect copper-based network devices to fiber optic segments. The RJ-45 port handles copper connections, while the SFP slot accepts various fiber optic modules for different connector types such as LC or SC.
What is the maximum data transfer rate?
This media converter supports Gigabit Ethernet with a maximum data transfer rate of 1000 Mbit/s (1 Gbps). It is compatible with 10/100/1000Base-T standards on the copper side and 1000Base-X on the fiber side, ensuring full-speed performance for applications like video streaming, data backups, or high-bandwidth network traffic.
