Transition Networks Gigabit Ethernet Media Converter Module 1000Base-T to 1000Base-SX/LX

The ION C3110 media converter module provides a reliable bridge between 1000Base-T copper Ethernet ports and 1000Base-SX/LX fiber ports, enabling seamless integration of fiber optic cabling into existing 1000Base-T copper environments. Operating at Layer 1, the physical layer, data is forwarded at line speed with no packet processing, preserving latency characteristics and throughput while expanding network reach. This makes it an ideal solution for enterprises, data centers, campuses, and branch offices that want to extend or segment networks without a full switch upgrade, while maintaining compatibility with a wide range of fiber media options.

• Seamless copper-to-fiber bridging: The C3110 converts 1000BASE-T copper Ethernet to 1000BASE-SX/LX fiber, enabling longer distances and cross-building connectivity without replacing existing copper ports. It preserves full line-rate throughput at 1 Gbps and maintains MAC-level transparency, so devices on either side communicate as if they were on one directly connected segment. This capability is especially valuable for campuses, data centers, and distributed sites where fiber provides performance, security, and EMI resistance while leveraging the strengths of your existing copper infrastructure.
• Fiber compatibility across SX/LX options: Supports 1000BASE-SX over multimode fiber and 1000BASE-LX over single-mode fiber via interchangeable SFP optics. The module accepts standard SFP transceivers that cover short-range (SX) and long-range (LX) fiber links, allowing precise distance planning and fiber type selection without changing copper interfaces. This flexibility enables you to tailor your network to current requirements and to evolve your fiber plant as needs grow, all while keeping the copper side intact.
• Layer 1 transparency with line-rate performance: As a pure physical-layer device, the ION C3110 forwards Ethernet frames at wire speed with no routing, switching, or packet manipulation. There is no IP processing, so latency remains minimal and predictable—critical for real-time applications such as voice, video, and time-sensitive data transfers. The transparent operation simplifies network design by letting administrators mix copper and fiber links without having to reconfigure connected devices or alter end-user equipment.
• Plug-and-play deployment in Transition Networks ION platforms: Engineered to slide into compatible ION chassis, the C3110 offers straightforward installation and smooth integration with existing infrastructure. It supports hot-swapping in supported environments, reducing downtime during maintenance. The module adheres to standard Ethernet practices, offering auto-negotiation and auto-MDI/MDIX, which minimizes cabling complexity and eliminates common misconfigurations. With clear LED indicators for link and activity, administrators can rapidly verify successful connections and scale their networks with confidence.
• Reliability, manageability, and future-proofing: Built for demanding environments, the C3110 emphasizes robust operation and straightforward maintenance. Its compact form factor fits standard rack shelves and cabinet spaces, while the absence of complex configuration reduces the probability of missteps. LED indicators provide immediate visibility into link status and activity, aiding ongoing monitoring and troubleshooting. This module supports reliable fiber extensions across campuses and data centers, enabling organizations to protect existing copper investments while embracing higher-bandwidth fiber connections where needed.

how to install Transition Networks Gigabit Ethernet Media Converter Module 1000Base-T to 1000Base-SX/LX

• Power down or prepare for hot-swapping: If your chassis supports hot-swapping, you may install the module without powering down the system; otherwise, safely power down the enclosure before insertion.
• Insert into an available slot: Align the C3110 module with an appropriate slot in a compatible ION chassis and firmly seat it to ensure proper electrical and mechanical connection.
• Connect copper side: Attach a standard Ethernet cable (Cat5e/6 or better) from the 1000Base-T device to the RJ-45 copper port on the module. Ensure the cable is securely seated to maintain a solid link.
• Install fiber SFP and connect fiber: Choose the appropriate 1000Base-SX/LX SFP transceiver for your fiber plant and install it into the fiber interface. Connect the fiber optic cable to the SFP according to the fiber type (multimode for SX, single-mode for LX) and connector style (LC/SC as applicable).
• Verify operation: Power on the chassis (if required) and check the status LEDs for copper link, fiber link, and activity. Use the connected devices to validate bidirectional communication and confirm stable throughput at 1 Gbps on both sides.
• Manage and monitor: If your network management tools are in use, monitor the media converter’s health and link status. While the C3110 operates at Layer 1, you can observe performance and uptime trends to plan capacity and future fiber upgrades.
