Keep fiber uplinks stable across longer distances with the D-Link DEM-310GT GBIC SFP. This 1,000 Mbps LX transceiver is designed for single-mode deployments that need clean handoff between switches, routers, and distribution equipment. The LC interface fits standard enterprise fiber infrastructure, while the LX optical profile supports the reach required for building-to-building links, campus runs, and remote network closets. For teams standardizing on Gigabit Ethernet, this module offers a straightforward way to add or replace optical connectivity without changing the surrounding architecture. It is a practical fit when you need predictable performance from a compact SFP form factor and want to preserve switch density. Compared with lower-cost optics that are often built for shorter runs or mixed environments, the DEM-310GT is aimed at the kind of link reliability infrastructure teams expect when the connection matters. Use it where fiber distance, signal integrity, and port efficiency all matter. The result is a cleaner network edge with fewer compromises and a transceiver that matches enterprise-grade deployment expectations.
