The D-Link DEM-311GT is a Gigabit SFP multimode fiber transceiver designed for short to medium-distance fiber optic network connections.
It is commonly used to connect switches, routers, and network devices within buildings, campuses, and structured LAN environments where multimode fiber cabling is already installed.
Unlike single-mode transceivers, this model is optimized for shorter distances up to 550 meters.
