Hanwha Techwin TMC-GSFP Transceiver/Media Converter

The Hanwha Techwin TMC-GSFP Transceiver/Media Converter is a compact, high-efficiency bridge that seamlessly connects copper Ethernet networks to fiber optics. Designed to maximize flexibility in smaller data centers, branch offices, and campus deployments, this device accepts a 10/100 or 1000 Mbps electrical input and converts it to a 100 or 1000 Mbps optical output, with the optical speed selected by a simple dip switch. The optical input at 100/1000 Mbps travels back through the converter to the electrical domain, enabling bidirectional communication without complex reconfiguration. With Auto-Negotiation support, the TMC-GSFP automatically negotiates the best speed and duplex settings with connected devices, reducing the likelihood of misconfigurations and making it easy to integrate into existing networks. Whether you’re extending reach over a fiber link, separating traffic into different network segments, or upgrading an aging copper-based infrastructure, this media converter offers a reliable, scalable solution that can adapt to changing network demands.

• Flexible speed conversion and bidirectional data flow: The TMC-GSFP accepts a 10/100/1000 Mbps electrical input and converts it to a 100/1000 Mbps optical output, with the optical speed selected via a dip switch. The device also converts the 100/1000 Mbps optical input back to electrical output, enabling smooth, two-way data transmission. This bidirectional capability is ideal for extending connectivity across fiber links without the need to replace existing copper-based devices, preserving your current network investments while unlocking the benefits of fiber.
• Dip-switch controlled optical speed: A straightforward dip-switch provides explicit control over the optical output speed, allowing you to configure the link for 100 Mbps or 1000 Mbps as required by your fiber infrastructure and distance constraints. This precise speed control helps optimize link reliability, minimize errors, and ensure compatibility with a wide range of fiber equipment, including legacy and modern transceivers. When you need tighter control over link performance or have specific distance limitations, the dip switch gives you a simple, reliable means to tune the connection.
• Auto-Negotiation for effortless integration: The TMC-GSFP supports Auto-Negotiation, enabling automatic speed and duplex negotiation with connected copper devices. This feature reduces manual configuration and compatibility issues across a mixed network of switches, routers, and end devices. With Auto-Negotiation, network administrators can deploy the converter quickly, knowing it will align with the capabilities of neighboring hardware and maintain stable, high-performance links without repeated adjustments.
• Compact, plug-and-play design for flexible deployments: The unit is designed for easy deployment in crowded network closets, equipment racks, or on workstations. Its compact form factor minimizes space requirements while delivering robust copper-to-fiber conversion. Because it operates without a complex management interface, IT teams can install and validate the connection rapidly, then scale the network by adding additional media converters as needed to accommodate growth or new fiber segments.
• Versatile deployment with the GSFP interface: The optical path uses a GSFP (Gigabit Small Form-Factor Pluggable) interface, enabling compatibility with standard fiber transceivers and allowing operators to pair the converter with appropriate optical modules for single-mode or multi-mode fiber as required. This flexibility supports a broad range of fiber types, link distances, and infrastructure standards, giving network planners greater latitude in designing future-proof architectures. The ability to select compatible transceivers helps optimize cost and performance across diverse environments.

How to install Hanwha Techwin TMC-GSFP Transceiver/Media Converter

• Power down the devices you will connect and confirm the installation environment meets general network safety and temperature operating guidelines.
• Insert the appropriate GSFP optical transceiver module into the optical port of the TMC-GSFP, if your kit requires a separate module. Ensure the module is fully seated and locked in place to prevent arcing or misalignment.
• Attach the fiber optic cable to the GSFP module, and connect the other end of the fiber to the remote device. Confirm the connector type (for example LC or SC) and ensure it matches the receiving equipment. Double-check fiber polarity and shielding where applicable.
• Connect the copper device to the TMC-GSFP’s RJ-45 port using a Cat5e/Cat6 Ethernet cable, and configure the source device for auto-negotiation if appropriate for your network design.
• Set the optical output speed on the dip switch to the desired 100 Mbps or 1000 Mbps, then power on all devices. Verify that link indicators illuminate on both ends and test connectivity with basic network tools to confirm throughput and stability.
• If the link does not establish, recheck the DIP switch settings, verify the fiber installation and connector integrity, and confirm that both ends are configured to the same speed and duplex settings. Validate that the installed GSFP modules are compatible with the chosen fiber type and distance.

Frequently asked questions

• What is the Hanwha Techwin TMC-GSFP Transceiver/Media Converter? It is a bidirectional media converter that bridges copper Ethernet (10/100/1000 Mbps) to fiber (100/1000 Mbps) and back, featuring auto-negotiation and a dip-switch to control optical speed for flexible deployments.
• What speeds are supported on each side? The copper side supports 10/100/1000 Mbps Ethernet, while the optical side supports 100 Mbps or 1000 Mbps depending on the dip-switch setting. The two sides work together to adapt to different network requirements.
• Is management software required? No. The TMC-GSFP is designed for straightforward plug-and-play operation with auto-negotiation, and it does not require dedicated management software for standard use.
