## Summary description

TP-LINK TL-SM311LS is a fiber optic SFP (mini-GBIC) transceiver supporting up to 1250 Mbit/s data rate and operating at 1310 nm wavelength. Compliant with IEEE 802.3z and RoHS, it provides a compact hot-pluggable interface for connecting switches and routers to single-mode fiber links for metropolitan or campus networks.

## Long description

The TP-LINK TL-SM311LS is a single-mode fiber SFP (mini-GBIC) transceiver that provides a hot-pluggable interface for extending Ethernet links over long distances. Supporting up to 1250 Mbit/s data rate and operating at a 1310 nm wavelength, this module is compliant with IEEE 802.3z and RoHS standards and is designed for use with compatible TP-Link managed and smart switches as well as supported media converters to create single-mode fiber links for metropolitan or campus networks.
Advantages
The TL-SM311LS single-mode MiniGBIC (SFP) module is compatible with SFP ports on TP-Link devices, including JetStream switches and the MC220L media converter, simplifying integration into existing networks. It supports long-distance connections to satisfy LAN transport requirements and enables per-port fiber deployment to reduce the need for additional equipment. The compact, hot-pluggable form factor allows easy installation and replacement without powering down the host device.
Suitable for
Extending Ethernet links over single-mode fiber in campus or metropolitan networks
Use with TP-Link managed and smart switches that feature SFP ports (including JetStream series)
Integration with supported media converters such as the MC220L and MC210CS (with single-mode fiber)
Key specifications
Form factor: Single-mode MiniGBIC (SFP)
Data rate: Up to 1250 Mbit/s
Wavelength: 1310 nm
Standards: IEEE 802.3z, RoHS compliant
Compatibility: All SFP ports on TP-Link products (including JetStream switches) and supported media converters such as MC220L; compatible with MC210CS when used with single-mode fiber
How to use
Insert the TL-SM311LS SFP transceiver into a compatible SFP port on a TP-Link managed or smart switch, or into a supported media converter. Connect single-mode fiber cables between the modules at each end of the link, then configure the connected devices to use the SFP interface as required by the switch or converter configuration. Verify link status via the device management interface and perform connectivity tests across the extended segment to confirm proper operation.
Usage recommendations
Use single-mode fiber cables and match module types at both ends of the link. Check device compatibility lists (JetStream switches, MC220L, MC210CS) before purchase to confirm support and ensure the installed SFP conforms to IEEE 802.3z and your network requirements.
