Product Description
The D-Link DEM-311GT is a versatile Gigabit Ethernet SFP (Small Form-factor Pluggable) transceiver module, commonly referred to as a mini-GBIC. It is specifically designed for high-speed network connections over multi-mode fiber optic cables, offering a cost-effective solution for short to medium-range data transmission. The module operates at a wavelength of 850nm, which is standard for short-reach MMF applications. With a data rate of 1 Gb/s, this transceiver is ideal for connecting network switches, routers, and servers within a building or across a campus. It supports distances of up to 550 meters on OM2 multi-mode fiber, providing sufficient reach for most local area network (LAN) environments. The use of an LC duplex connector ensures a secure and reliable physical connection. The DEM-311GT adheres to the SFP Multi-Source Agreement (MSA), guaranteeing compatibility with a wide array of networking equipment from various manufacturers. Its hot-swappable design allows for easy installation and replacement without the need to power down the host device, contributing to network uptime and simplified management.
