D-Link SFP transceivers, DAC cables and media converters

D-Link DEM series transceivers and direct-attach cables fit the SFP, SFP+ and QSFP ports of D-Link switches. DMC media converters bridge copper and fibre where a device has no fibre port.

What this range covers

  • Gigabit SFP transceivers (DEM-31x) for multi-mode and single-mode fibre
  • 10-gigabit SFP+ transceivers (DEM-43x) and bidirectional modules
  • Direct-attach copper cables (DEM-CB series) for short rack links
  • QSFP and 25-gigabit modules for core switches
  • DMC media converters and chassis

Typical applications

  • Switch-to-switch uplinks in buildings
  • Core and distribution links in server rooms
  • Fibre to camera poles and gate houses
  • Connecting legacy copper devices to a fibre backbone

Key capabilities

  • Modules chosen by speed, fibre type and distance
  • Direct-attach cables for low-cost links within a rack
  • Hot-pluggable transceivers
  • Bidirectional modules that use a single fibre strand

Functions vary by model and firmware; see each model page and the official datasheet.

Selection questions

  • Which switch and port type will take the module?
  • Single-mode or multi-mode fibre, and how far?
  • Is the link inside one rack, where a DAC cable may be enough?

Frequently asked questions

What is a DAC cable?

A direct-attach copper cable with SFP+ or QSFP ends built in, used for short links between switches in the same rack.

Do D-Link modules work only in D-Link switches?

Modules are coded for D-Link switches; check the switch documentation for the module list of each model.

Which fibre products does ISD list for D-Link?

The model list links every DEM and DMC reference with its own page on this site.
