Product Overview
The TRENDNET TFC-GMSC is a high-performance Gigabit Ethernet media converter designed to transparently connect 1000Base-T copper networks to 1000-SX fiber infrastructures. Engineered with an external form factor, the compact unit features one Auto-MDIX Gigabit port and one SC-type fiber port, supporting both 100/1000 Mbps fiber connectivity. This converter supports multi-mode optical fiber with distances of up to 550 meters for 50/125 µm cables and up to 220 meters for 62.5/125 µm cables, and allows Cat.5e/6 cabling up to 100 meters.
Compliance with IEEE networking standards (IEEE 802.3, 802.3u, 802.3ab, and 802.3z) ensures compatibility across a wide range of networking environments. The device is TAA compliant and manufactured in Taiwan, offering assurance in government and regulated deployments. Its compact housing—just under 1 inch in height—allows flexibility in mounting and deployment in tight spaces. Backed by a 3-year limited warranty, the TRENDNET TFC-GMSC provides a cost-effective long-range media extension solution for businesses upgrading to fiber without changing their existing copper infrastructure.
