Designed to support distances up to 10 kilometers, the DEM-422XT is a high performance 1310nm Single-mode XFP transceiver. Supporting Full-duplex, 10Gigabit speeds on Single-Mode fiber cables, the DEM-422XT is 802.3ae 10GBASE-LR compliant and supports Full-duplex 802.3x Flow control. The DEM-422XT provides the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa. The DEM-422XT is hot swappable. You can remove or replace the transceiver with the system powered on. This permits transceivers to be added or swapped without interrupting network systems.
