Transition Networks 10/100/1000Base-TX to 1000Base-SX Media Converter

Bridge your aging copper Ethernet with modern fiber optics using Transition Networks’ compact 10/100/1000Base-TX to 1000Base-SX media converter. This mini, unmanaged device is designed to slip into tight spaces while delivering dependable, high-speed connectivity between a copper network and a fiber backbone. The -NA power supply version ensures seamless regional compatibility for North American outlets. Whether you’re upgrading a tiny office, expanding a data center edge, or extending campus reach, this media converter provides a cost-effective, plug-and-play path to higher bandwidth and longer distances without the need for complex configuration or major network downtime.

• Flexible speed and seamless migration: The copper RJ-45 port auto-negotiates 10/100/1000 Mbps with full or half‑duplex operation, while the 1000Base-SX fiber port delivers reliable gigabit performance over multimode fiber. This design makes it straightforward to extend an existing copper Ethernet network onto a fiber backbone without replacing devices or rewiring your racks.
• SC multimode fiber interface optimized for campus and building networks: Featuring an SC connector and 850 nm wavelength for multimode fiber, this converter supports short-to-mid reach links with robust performance, reduced EMI exposure, and improved signal integrity compared with copper-only links. It’s ideal for linking switches, routers, and servers across floors or separate buildings.
• Compact, rugged design for flexible deployment: The mini metal enclosure is purpose-built for space-constrained environments. Its compact footprint, quiet operation, and durable construction enable desktop placement, wall mounting, or integration into small rack systems, delivering reliable service in data closets, labs, and edge deployments.
• Plug-and-play reliability with broad compatibility: As an unmanaged device, it requires no software or complex configuration. Connect devices, attach fiber, apply power, and you’re ready. It adheres to standard IEEE Ethernet specifications and supports auto MDI/MDIX on the copper port, ensuring straightforward cabling regardless of from which side devices are connected.
• Regionally appropriate power supply and safety compliance: The -NA power supply included is designed for North American outlets, with safety and EMI certifications to support enterprise deployments. This ensures a safe, compliant installation in offices, schools, and smaller data centers without extra adapters or region-specific purchases.

how to install Transition Networks 10/100/1000Base-TX to 1000Base-SX Media Converter

• Prepare the site and verify the -NA power supply is included and compatible with your outlet. Ensure the operating environment is within typical temperature and ventilation guidelines for compact network devices.
• Power down devices you plan to connect, then connect the copper side of the converter to the source device using a Cat5e/Cat6 Ethernet cable. Ensure the RJ-45 link is secure and aligned correctly for the port.
• Attach the fiber link by inserting multimode SC fiber into the SC fiber port on the converter, verifying correct connector seating and polarity to prevent signal loss.
• Connect the other end of the fiber link to your network device (for example, a switch or fiber-ready router) to establish the 1000Base-SX uplink. Confirm that the receiving device is prepared to accept gigabit fiber input.
• Apply power to the converter and power on both connected devices. Since this is an unmanaged converter, the link should establish automatically; check link indicators on the unit and the connected equipment to confirm connectivity and performance. Mount or place the unit as needed for optimal airflow and cable management.
