Product Highlights Covers Vast Distances Support for maximum cable lengths of between 550 meters and 80 kilometers1 is ideal for businesses spanning multiple premises High Performance Full duplex Gigabit data transfer rates provide the network transmission speeds that business environments demand Hot Pluggable Easily switch out transceivers while the power is on, facilitating network maintenance and minimizing downtime Gigabit SFP/Ethernet Transceivers Features D-Link Gigabit SFP Transceivers plug into Gigabit and Fast Ethernet switches via their • Small Form factor Pluggable (SFP) GBIC slots. They allow for the expansion of Gigabit Ethernet networks by providing high- • Multi-Source Agreement (MSA) specification compliant speed connections over a fiber-optic or twisted-pair cable. The fiber-optic transceivers have standard duplex LC connectors to provide maximum compatibility. They are hot pluggable and Small Form Factor Pluggable (SFP) compliant with the Multi-Source • Supports cable distances of up to 100 m / 550 m / 2 km / 10 km / 40 km / 50 km / 80 km1 • Hot pluggable • FDA, CDRH, TUV Laser Eye safety certified • TTL signal detect indicator • Metal enclosure reduces EMI Small Form Pluggable (SFP) Package The Gigabit SFP/Ethernet 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. Multiple Applications Applications of the DEM-300 Series fiber transceivers include distributed multiprocessing, 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. 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 reduc
