SFP Transceivers

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.

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.
