D-Link’s new line of Small Form-Factor Pluggables (SFPs) transceivers give you an industry-leading combination of performance and affordability. The DEM-311GT is a high-performance 850 nm multi-mode SFP transceiver supporting Gigabit speeds on multi-mode fiber for distances of up to 550 m. The unit features a metal housing to reduce EMI and to increase durability.
All D-Link transceivers are hot pluggable. You can connect a transceiver while the system is powered on without causing any issues, and easily swap one for another without having to reboot the switch each time. This permits modules to be added or removed without interrupting the network, facilitating maintenance and greatly reducing downtime.
The Gigabit SFP Transceivers use the Small Form-factor Pluggable (SFP) design. They provide the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa. The SFP form factor is advantageous because it is smaller than other form factors such as Xenpak, X2, and 10G XFP, ensuring lower costs, lower power disruption, and higher port density.
