TP-Link TL-SM311LS network transceiver module Fiber optic 1250 Mbit/s mini-GBIC/SFP 1310 nm

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

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.

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.
