Fast Ethernet SFP Transceivers

D-Link’s SFP transceivers provide a high-performance solution for serial optical data communication applications. They are hot-pluggable and Small Form Factor Pluggable (SFP) compliant with the Multi-Source Agreement (MSA) specification.

Small Form-factor Pluggable Format

The Fast Ethernet 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.

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.

Superb Performance

D-Link’s highly integrated transceivers offer low-jitter performance for extended optical links support without performance degradation. This high performance enables reliable data transfer in short, intermediate, and long distances for building, factory, campus and metropolitan networking applications.
