TP-Link TL-SM331T Gigabit 1000BASE-T SFP Transceiver, RJ45 Connector (up to 100m)

The SM331T is a TP-Link SFP transceiver module — the small pluggable that turns an empty SFP slot on a switch into a live uplink. Slot it into the switch at each end of the run, connect the cabling, and the link comes up with no configuration required.

It fits the SFP slots found across TP-Link's switch range, from the Omada SG3452 and SL2428P to compatible third-party hardware. The right module depends on your cable type and distance, so tell us about the run and we will confirm this is the correct transceiver before you order.

Frequently asked questions

What is an SFP module for?

Switches ship with empty SFP slots so you choose the media: the module you fit determines what the port speaks. It is how uplinks between cabinets, floors or buildings are made without committing the switch to one cable type.

How do I know this is the right module?

Match the module to the cabling and the distance of your run, and fit a compatible module at each end. Tell us both details and your switch models and we will confirm before dispatch.

Is it difficult to fit?

No — SFP modules are hot-pluggable: push the module into the slot, connect the cable and the port comes up automatically.
