D-Link DEM-311GT network transceiver module Fiber optic 1000 Mbit/s SFP 850 nm
Description
High-Speed Network Transmission for Business Environments
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.
Hot Pluggable
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.
Multiple Applications
Applications of the DEM-300 Series fiber transceivers include distributed multi-processing, Gigabit switch cascading, high-speed I/O file transfer, bus extension application, and channel extender/data storage. This versatility is invaluable for an expanding network, and helps the infrastructure grow with the business.
Small Form Pluggable (SFP) Package
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.
