D-Link Gigabit SFP Transceivers plug into Gigabit and Fast Ethernet switches via their GBIC
slots. They allow for the expansion of Gigabit Ethernet networks by providing high-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 Agreement (MSA) specification.

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.

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.

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.
