Frequently Asked Questions — D-Link DEM-432XT
How far can the DEM-432XT reach?
Up to 10 km on single-mode fibre, per D-Link's datasheet.
Does it support DDM?
DDM is not listed for the DEM-432XT. If you need optical diagnostics, choose the DEM-432XT-DD.
Can I use it on multi-mode fibre?
No — it is a single-mode (9/125 µm) optic. For multi-mode fibre choose the DEM-431XT.
What warranty do I get?
5 years local warranty in Singapore, supplied by SourceIT with a GST invoice.
