Choosing a refurbished Cisco GLC-LH-SMD 1000BASE-LX/LH SFP transceiver is a smart, budget-friendly approach to maintaining or expanding your Gigabit Ethernet network. This refurbished module delivers the same high-speed 1.25 Gbps performance and core features as a new unit, but at a significantly reduced cost. Each refurbished GLC-LH-SMD undergoes thorough testing and certification processes to ensure it meets or exceeds the original Cisco operational standards for reliability and performance. This module is designed for long-reach connectivity, supporting distances up to 10 kilometers over single-mode fiber (SMF) and up to 550 meters over multi-mode fiber (MMF)—the required mode conditioning patch cable for MMF remains the same. The module retains its essential Digital Optical Monitoring (DOM) capability, allowing your network team to actively track vital metrics like temperature and optical power, which is key for system stability and proactive troubleshooting. Operating at the standard 1310 nm wavelength and featuring a Duplex LC connector, the refurbished GLC-LH-SMD integrates smoothly with Cisco switches and routers, providing a reliable and hot-swappable solution. It is fully compliant with the IEEE 802.3z 1000BASE-LX standard. By opting for a tested, refurbished GLC-LH-SMD, businesses can realize substantial hardware cost savings while maintaining the high quality and performance required for demanding network backbones and extending long-distance fiber links.
