SFP Module TP-Link TL-SM331T 1000BASE-T RJ45

The TP-Link TL-SM331T 1000BASE-T RJ45 SFP module provides a compact, hot-pluggable solution to extend a copper Ethernet connection up to 100 metres via an SFP interface. It supports gigabit speeds with a maximum data transfer rate of 1250 Mbit/s, operates at 3.3 V input, and comes in a durable metal silver casing. The module is FCC- and CE-certified and fits standard SFP ports for flexible network expansion.

Advantages

The module delivers a gigabit port for high-speed connectivity over existing copper cabling and supports data transmission up to 100 metres. Its plug-and-play design enables easy installation without the need for a technician. A metal housing provides mechanical strength and consistent performance across a range of environments. TL-SM331T is compatible with many SFP-enabled devices from major vendors.

Suitable for

• Extending SFP-enabled switch or router ports to RJ45 copper networks
• Connecting servers, switches or routers in data centres and wiring closets
• Upgrading network links to gigabit speed over short copper runs (up to 100 m)

Ensure the connected devices are powered and configured as needed; the module operates as plug-and-play in most environments. Observe proper handling to avoid electrostatic discharge when installing the module.

Usage recommendations

Use Cat5e or better Ethernet cable for runs up to 100 metres to achieve gigabit performance. Verify device compatibility and firmware support on the host equipment if the module does not recognise immediately; consult vendor compatibility lists for specific models.
