Frequently Asked Questions
What is the DEM-432XT used for?
The DEM-432XT is a 10GBASE-LR SFP+ optical transceiver for 10GbE links over single-mode fiber. Applications include building-to-building fiber links, campus network backbones, network aggregation and enterprise wiring closet uplinks.
What fiber and connector does it use?
The DEM-432XT uses 1310 nm optics and a duplex LC connector. It uses two strands of 9/125 µm single-mode fiber.
How far can the link reach?
The rated reach is up to 10 km (6.2 mi) over single-mode fiber. Actual reach depends on total optical loss across the link.
Which D-Link switches can I use it with?
10GbE SFP+ uplinks are supported on applicable DGS-3130, DGS-3630, DGS-1530, DGS-1250 and DGS-1510 models, as well as the DXS-3130-32S.
The DXS-3130-28P and supported DMS-3130 models can use the module in compatible SFP28 uplinks operating at 10GbE. Contact D-Link to confirm support for other switch models.
What should I check before deploying the link?
Confirm that both host ports support their respective optics at 10GbE and that the far-end optic supports 10GBASE-LR. Verify that transmit connects to receive across the duplex LC link. Check total optical loss, including connectors, splices and patch panels.
Can I replace the transceiver while the switch is powered on?
Yes. The module is hot-pluggable and can be installed or removed while the switch remains powered on. Removing the module interrupts the link it serves.
Are the switch and fiber cabling included?
Switches and fiber cabling are sold separately.
