Description
The TP-Link TL-SM311LS is a high-performance 1000Base-LX MiniGBIC SFP transceiver designed to extend the reach of local area networks. Operating at a 1310nm wavelength over single-mode fiber, it facilitates reliable data transfer rates of up to 1.25Gbps across distances reaching 10 kilometers. This module is engineered for stability and ease of use, featuring a plug-and-play design that allows for installation without powering down the host switch, ensuring zero network downtime during upgrades.
This product is for:
- Network Administrators: Professionals managing campus or enterprise networks requiring long-distance fiber uplinks between buildings.
- IT Infrastructure Installers: Technicians looking for reliable, standardized SFP modules that comply with IEEE 802.3z for seamless integration.
- Small to Medium Businesses (SMBs): Organizations upgrading from copper to fiber to reduce electromagnetic interference and increase bandwidth capacity.
- Data Center Operators: Facilities requiring high-density, hot-swappable interconnects for managed switches like the TL-SG3428 or TL-SG3452.
- Surveillance System Integrators: Users deploying IP cameras over large areas where standard Ethernet cabling exceeds the 100-meter limit.

Deploying the TL-SM311LS is straightforward due to its hot-swappable nature, which eliminates network downtime during maintenance or hardware expansion. The LED indicators on the host switch provide immediate feedback on the link status, ensuring that the 1.25Gbps full-duplex connection is active and healthy. Its low power consumption and robust metal housing contribute to long-term thermal stability, even when used in high-density switch environments where heat management is critical.
Compared to multi-mode SFP modules like the TL-SM311LM, which are limited to 550 meters, the TL-SM311LS utilizes single-mode fiber to achieve a significantly longer 10km range. While copper SFP modules are restricted by the 100-meter Ethernet limit, this 1310nm optical module provides the necessary reach for metropolitan area networks (MAN) and inter-building connectivity without signal degradation. It serves as a cost-effective alternative to proprietary brand transceivers while maintaining full compatibility with TP-Link's extensive line of JetStream switches.
Q&A:
- What is the maximum distance supported by the TL-SM311LS? This module supports a maximum transmission distance of 10 kilometers (6.2 miles) using 9/125μm single-mode fiber.
- Is the TP-Link TL-SM311LS hot-swappable? Yes, it supports hot-plugging, meaning you can install or remove the module while the switch is powered on without interrupting other ports.
- Which fiber connector type does this module use? The TL-SM311LS features an LC/UPC duplex connector, which is the industry standard for SFP transceivers.
- Can I use this module with multi-mode fiber? No, the TL-SM311LS is specifically designed for single-mode fiber (SMF). Using it with multi-mode fiber will result in significant signal loss and link failure.
- What TP-Link switches are compatible with this SFP module? It is compatible with a wide range of TP-Link managed and smart switches, including the TL-SG3428, TL-SG3452, and older models like the TL-SG3109 and TL-SL3452.
