Overview
- The TP-Link SM311LM is a multi-mode mini-GBIC SFP module engineered to extend the transmission distance of TP-Link managed and smart switches without requiring additional power supplies. By supporting transmission distances up to 550 metres over multi-mode fibre optic cable, the module enables businesses to build larger, more flexible network architectures at lower cost than alternative solutions.
Designed for seamless integration, the SM311LM supports hot-swap operation, allowing installation and removal without powering down the switch. Its plug-and-play nature simplifies deployment, whilst full-duplex support ensures bidirectional communication at full line rate. The module draws power internally from the host switch, eliminating external power requirements and reducing installation complexity.
With IEEE 802.3z compliance and support across TP-Link's extensive switch portfolio, the SM311LM is ideal for network professionals seeking to extend LAN reach reliably. Operating across a wide temperature range from 0°C to 70°C, it performs consistently in most Australian environments.

FAQs
What is the maximum distance the TP-Link SM311LM can transmit data?
The SM311LM supports multi-mode fibre transmission up to 550 metres, making it suitable for extending network reach across larger office buildings and campuses without additional equipment.
Which TP-Link switches are compatible with the SM311LM?
The SM311LM is compatible with a range of TP-Link managed and smart switches, including the TL-SG5428, TL-SG3210/3216/3424/3424P, TL-SG2216/2424, TL-SL series, and MC220L. Check the compatibility list before purchase.
Does the SM311LM require external power?
No. The module draws power internally from the host switch (3.3V supply), eliminating the need for external power supplies and simplifying installation.
Can I hot-swap the SM311LM without powering down my switch?
Yes. The SM311LM supports hot-swap operation, allowing you to install or remove it whilst the switch remains powered on and operational.
What type of fibre cable does the SM311LM use?
The module supports multi-mode fibre with either 50/125μm or 62.5/125μm core and cladding dimensions, and uses LC/UPC connectors for reliable connections.
Is the TP-Link SM311LM standards-compliant?
Yes. The module conforms to IEEE 802.3z standards and has achieved FCC and CE certifications, ensuring reliable and safe operation in professional network environments.
What wavelength does the SM311LM operate at?
The module operates at 850nm wavelength, which is the standard for multi-mode fibre optic short-reach applications in local area networks.
