Overview
- The TP-Link TL-SM331T is a 1000BASE-T RJ45 SFP transceiver module that enables Gigabit Ethernet connectivity using standard copper cabling infrastructure. With a maximum reach of 100 metres over Cat 5e or above cable, it provides a practical solution for extending network capacity without requiring fibre optic installation.
Designed for compatibility with IEEE 802.3-2002 standards, the TL-SM331T features a hot-swappable SFP form factor, allowing technicians to install or replace it without powering down host equipment. The module's TX Disable function provides additional network management capability, enabling remote control of port status.
The fully metallic enclosure minimises electromagnetic interference, whilst low power dissipation (0.5 W typical) reduces operational costs and heat generation in switch fabric environments. With a 36-month warranty, the TL-SM331T is a reliable choice for organisations seeking to maximise existing network infrastructure investments.

FAQs
What is the maximum cable length for the TP-Link TL-SM331T?
The TL-SM331T supports a maximum cable length of 100 metres when used with Cat 5e cabling or above. This makes it suitable for connecting switches and routers across standard office and data centre distances.
Can the TL-SM331T be installed without powering down my switch?
Yes. The TL-SM331T features a hot-swappable SFP footprint, allowing you to insert or remove the module whilst the host device remains powered and operational. This minimises network downtime during upgrades and maintenance.
What is the TX Disable function and why is it useful?
The TX Disable function allows you to remotely disable transmission on the module without physically removing it from the switch. This is useful for network troubleshooting, maintenance windows, and traffic management without causing service interruptions.
Is the TL-SM331T compatible with non-TP-Link network equipment?
Yes. The TL-SM331T complies with IEEE 802.3-2002 standards and is compatible with any SFP-capable switch or router that supports 1000BASE-T operation. Compatibility should be confirmed with your specific hardware vendor.
What is the power consumption of the TL-SM331T?
The module consumes 0.5 W in typical operation and 0.8 W maximum. This low power profile makes it ideal for power-conscious data centre environments and reduces heat generation in high-density switch deployments.
What cabling do I need for the TL-SM331T?
The TL-SM331T uses a standard RJ45 connector and requires Cat 5e or above unshielded twisted pair (UTP) cabling for distances up to 100 metres. Standard Ethernet patch cables are compatible.
What certifications does the TL-SM331T carry?
The TL-SM331T is certified to FCC and CE standards, ensuring compliance with electromagnetic interference and safety regulations for deployment in commercial and enterprise environments.
