D-Link DEM-431XT 10G SFP+ Multimode Transceiver

SKU CH-0240-JCCNQ

Adds 10 Gbps fibre links up to 300 metres to SFP+ switches via Duplex LC multimode, hot-pluggable and MSA-compliant

  • Add 10 Gbps fibre links up to 300 m
  • Hot-pluggable SFP+ module cuts maintenance downtime
  • MSA compliant for multi-vendor switch compatibility
  • IEEE 10GBASE-SR certified for short-range multimode
  • RoHS compliant restricted-hazardous-substances design

10G SFP+ Transceiver for Fibre Upgrades

The D-Link DEM-431XT is a hot-pluggable optical transceiver that adds 10 Gigabit Ethernet connectivity over multimode fibre. It targets network administrators upgrading D-Link switches with SFP+ slots to support fibre links up to 300 metres. The module uses a Duplex LC connector and complies with the Multi-Source Agreement for multi-vendor interoperability.

Replaces Copper Uplinks for Longer Reach

This transceiver replaces direct-attach copper cables or 1G fibre modules when aggregate throughput or distance exceeds copper limits. The jump is worth it when switch-to-switch or switch-to-server links require 10 Gbps bandwidth across building floors or between racks where multimode fibre is already installed. It supports the IEEE 10GBASE-SR standard for short-range operation.

Fits SFP+ Slots Without Power Cycling

The module plugs directly into any MSA-compliant SFP+ port on a compatible switch, requiring no tools or system reboot for installation. Hot-pluggable operation frees maintenance windows by allowing transceiver swaps while the network remains live. RoHS compliance ensures the component meets hazardous-substance restrictions for regulated environments.

Questions about this item

What type of SFP+ slot and fibre connector does the DEM-431XT require?

The DEM-431XT fits a standard SFP+ port and uses a Duplex LC connector for multimode fibre.

Can the transceiver be inserted or removed while the switch is powered on?

Yes, the module is hot-pluggable so you can swap it without shutting down the switch, avoiding unnecessary downtime.

When should the transceiver be replaced if link errors appear?

Replace the module if cleaning the Duplex LC connectors and verifying the multimode fibre run does not resolve persistent errors.
