## Summary description

The TP-Link TL-SM311LS is a mini-GBIC/SFP fiber optic transceiver module with a maximum data transfer rate of 1250 Mbit/s. It is designed for high-speed network connections and is compliant with RoHS standards. This product comes in a pack of 8 units, making it ideal for bulk installations.

## Long description

The TP-Link TL-SM311LS is a mini-GBIC/SFP fiber optic transceiver module that supports a data transfer rate up to 1250 Mbit/s. Designed for use with managed and smart switches, this module enables extension of network links over fiber to distances of several kilometers or more, meeting typical LAN distance requirements. The product is RoHS compliant and is supplied in an 8-unit pack for bulk installations.
Advantages
The TL-SM311LS offers reliable fiber connectivity in a compact mini-GBIC/SFP form factor, allowing network administrators to extend Ethernet links without replacing existing switching equipment. Its single-rate 1250 Mbit/s operation and compatibility with common TP-Link switches simplify deployment, while the multi-unit pack reduces per-unit cost for larger installations.
Suitable for
Extending Ethernet links between switches across buildings or campus environments
Replacing or adding SFP fiber ports in managed or smart TP-Link switches
Bulk installation projects requiring multiple identical fiber transceivers
Key specifications
Form factor: mini-GBIC / SFP
Data rate: 1250 Mbit/s (1.25 Gbps)
Connector type: fiber optic (SFP transceiver)
Compliance: RoHS
Packaging: 8 units per pack (SM311LS(8-pack)(UN))
Brand: TP-LINK
EAN: 8885020622126
How to use
Install the TL-SM311LS module into an available SFP slot on a compatible managed or smart switch until it clicks into place. Connect the appropriate fiber optic cable to the transceiver, ensuring correct connector type and polarity. Configure the switch port as needed (speed, duplex, VLANs) and verify link status through the switch management interface. For multiple modules, repeat the process for each SFP slot required.
Usage recommendations
Use certified single-mode or multimode fiber and compatible connectors per the switch documentation; verify fiber type and distance limitations before deployment. Handle the transceiver by the housing, keep optical interfaces clean, and store unused modules with protective caps to prevent contamination.
