D-Link SFP Transceiver Overview

D-Link Gigabit Interface Converters are transceivers that connect Gigabit switches and 10/100Mbps switches with GBIC slots to Gigabit Ethernet networks, providing high-speed connections over the fiber optic or twisted pair cable. The fiber optic transceivers have standard duplex LC connectors for connection compatibility.

Overview

• DEM-310GT, 1000BASE-LX SFP 1310nm 10km, SMF
• DEM-311GT, 1000BASE-SX SFP 850nm 550m, MMF
• DEM-314GT, 1000BASE-LX SFP 1310nm 50km, SMF
• DEM-315GT, 1000BASE-LX SFP 1550nm 80km, SMF

Small Form Pluggable (SFP) Package

These transceivers use the industry-standard Small Form Pluggable (SFP) package. They slide into the mini GBIC slot of the Gigabit device. They provide the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa, for the port to receive data from the network cable.

Hot Swappable

All D-Link Mini GBIC transceivers are hot-swappable. You can remove or replace the GBIC transceiver with the system powered on. This permits modules and mini-GBICs to be added or swapped without interrupting the network.

Applications

Applications of the fiber transceivers include distributed multi-processing, Gigabit switch cascading, high-speed I/O file transfer, bus extension application, and channel extender/data storage.
