TP-Link 10GBASE-SR SFP+ Transceiver

The TP-Link SM5110-SR is an 850 nm multi-mode SFP+ transceiver that adds a 10 Gbps Ethernet link over LC/UPC fibre. It targets network administrators upgrading enterprise switches or data-centre gear to 10 Gbps speeds.

Sustained 10 Gbps multi-mode operation

The module maintains full-duplex 10 Gbps throughput across the declared distances of 300 m on 50/125 µm fibre and 33 m on 62.5/125 µm fibre. Digital Diagnostic Monitoring reports real-time optical parameters so link health stays visible under continuous load. Hot-pluggable insertion avoids downtime during capacity changes.

Compatibility checks before ordering

Verify that your switch provides standard SFP+ slots and supports the SFP+ MSA specification used by this transceiver. Confirm the installed fibre plant uses multi-mode cable with either 50/125 µm or 62.5/125 µm cores to match the supported reach. Ensure LC/UPC patch cords are available for the connection.

Questions about this item

Does the TL-SM5110-SR generate noticeable heat or noise when running continuously in a 10G SFP+ slot?

The module is a passive optical transceiver with no moving parts, so it adds minimal heat and produces no audible noise during continuous operation.

What cabling and switch port does the SM5110-SR require to establish a 10G link?

You need a switch with an SFP+ slot and a multi-mode LC/UPC patch cord — 50/125 µm fibre for up to 300 m or 62.5/125 µm fibre for up to 33 m.

Will this transceiver work in an older switch that only has 1 Gbps SFP ports?

No, the SM5110-SR is a 10GBASE-SR module and requires a 10G SFP+ port; it will not operate in a 1 Gbps SFP slot.
