M/GE-UxX Seriess

The Transition Networks M/GE-UxX Series are mini gigabit Ethernet unidirectional media converters that can change a signal from a regular computer network (10/100/1000Base-T) into a signal that can travel over fiber optic cables (100/1000Base-X). This type of conversion is often used in secure environments like the military and government because it helps keep sensitive information safe. A unidirectional converter, also called a data diode, only lets information flow in one direction, making it hard for someone to steal the information. By using fiber optic cables instead of regular cables, the information being transmitted is more secure because it is difficult to tap into a fiber optic cable without being detected. The unidirectional feature of the media converter adds another layer of security, making sure that sensitive information only goes in one direction and can’t be taken out. This allows information from a secure network to be sent to a less secure network, but keeps the sensitive information from going the other way.

Key Features:

  • Unidirectional Data Transmissions: This media converter allows one-way communications over fiber, providing a secure, physically isolated connection between secure and unsecure networks. It ensures data can only flow in the designated direction, safeguarding classified information from unauthorized access.
  • Simplex Communications: With simplex communications requiring just one strand of fiber cable, the installation becomes more straightforward, reducing complexity and cost while maintaining high-level security.
  • Transmit-Only and Receive-Only Converters: To create a unidirectional link, you can pair a transmit-only converter with a receive-only converter, guaranteeing data can only be sent or received, never both ways.
  • Dual-Speed 100/1000Mbps SFP Modules: The converters support versatile SFP modules, offering flexibility to meet your network requirements efficiently.
  • LED Status Indicators: The unit and port LEDs provide quick and easy status information, allowing for smooth monitoring and troubleshooting.
  • Auto-Negotiation and Auto-MDI/MDIX: The converter supports Auto-Negotiation on the 10/100/1000 copper port, making network setup hassle-free. Additionally, the Auto-MDI/MDIX configuration ensures seamless connections with various networking devices.
  • Jumbo Frame Support: This feature allows for the efficient transmission of larger data frames, optimizing network performance.


  • Enhanced Network Security: By utilizing unidirectional technology, this media converter provides a secure one-way communication channel over fiber, keeping your classified and high-security data isolated from the unsecure network. This prevents unauthorized data from re-entering the secure network, reducing the risk of data breaches.
  • Cost-Effective Solution: The M/GE-xSW-SFP-01-xx-UxX Series offers a cost-effective approach to secure network communications. Instead of investing in complex and costly security measures, you can achieve robust data protection with this single, reliable solution.
  • Increased Network Reliability: The deployment of fiber adds a layer of security to your network as it is difficult to tap into fiber and go undetected. In case of any threats, the fiber links go down, promptly alerting network administrators and enabling them to address potential security breaches promptly.
  • Easy Installation and Configuration: The converters are designed to be plug-and-play, simplifying the setup process. Additionally, the LED status indicators make it easy to monitor the converters’ performance and connectivity.
  • Wide Operating Temperature Range: With options available for both enterprise-grade and hardened-grade converters, you can choose the one that best suits your environmental requirements, ensuring reliable performance even in harsh conditions.
