10GBASE-LR Single-Mode XFP Transceiver

The D-Link DEM-422XT is a hot-swappable XFP transceiver built for 10 Gigabit Ethernet links over single-mode fibre. It targets network engineers extending campus or metro connections up to 10km using 1310nm wavelength optics. The module complies with IEEE 802.3ae 10GBASE-LR and supports full-duplex 802.3x flow control for reliable throughput.

LC Duplex Interface and Industrial Temperature Range

A duplex LC connector provides the physical link to 9/10 micron core single-mode fibre, enabling straightforward patching in dense patch panels. The transceiver operates from -5 to 70 °C in humidity up to 85 percent, making it suitable for equipment rooms without precision cooling. Power input accepts both 3.3V and 5V rails, easing integration into mixed-voltage line cards.

Distance and Form-Factor Constraints

The 10km reach is defined by the 10GBASE-LR standard and 1310nm optics; longer spans require different wavelengths or amplification not provided here. The XFP form factor measures 3.1 by 0.7 by 0.5 inches, so the host chassis must accommodate XFP cages rather than the smaller SFP+ footprint. Buyers needing higher port density or shorter-reach multimode links should select alternative form factors.

Questions about this item

What IEEE standard does the DEM-422XT follow, and what distance does 10GBASE-LR cover?

It complies with IEEE 802.3ae 10GBASE-LR and supports single-mode fibre links up to 10,000 meters.

What are the exact dimensions of the DEM-422XT, and will it fit a standard XFP cage?

The module measures 3.1 by 0.7 by 0.5 inches, matching the standard XFP form factor for compatible cages.

Can the DEM-422XT be swapped without powering down the switch, and what is the correct insertion method?

Yes, it is hot-swappable; align the module with the cage rails and push firmly until the latch clicks to seat the LC connector properly.
