FAQs
What is the maximum distance the TP-Link SM311LS can transmit?

The SM311LS supports transmission distances up to 20 km over standard 9/125 μm single-mode fibre, making it suitable for long-distance network connections between buildings or across larger campuses.

Which TP-Link switches are compatible with this SFP module?

The SM311LS is compatible with TP-Link's managed switch range, including JetStream switches (T3700G-28TQ, TL-SG5412F, TL-SG5428, TL-SG3210, TL-SG3216, TL-SG3424, TL-SG3424P, TL-SG2210P, TL-SG2216, TL-SG2424, TL-SG2424P, TL-SG2452), plus media converters like the MC220L and MC210CS.

Is the SM311LS a hot-swappable module?

Yes, the MiniGBIC form factor allows the module to be installed and removed without powering down the switch, enabling flexible network upgrades and maintenance.

What type of fibre cable do I need for this module?

The SM311LS requires standard single-mode fibre (SMF) with 9/125 μm core and cladding dimensions. This is the industry-standard specification for long-distance single-mode connections.

Does this module work with third-party switches?

The SM311LS is optimised for TP-Link products. Whilst it features an industry-standard LC connector and SFP form factor, compatibility with non-TP-Link switches should be verified before deployment.

What warranty coverage is included?

The TP-Link SM311LS comes with a 36-month manufacturer's warranty, covering defects in materials and workmanship.
