## Long description

The TL-SM311 series fiber module cards extend network transmission distance when used with compatible managed or smart switches. Installed in the appropriate slot, these fiber modules enable links that span several kilometers up to tens of kilometers to meet LAN distance requirements while allowing users to select modules as needed to control costs.
Advantages
The TL-SM311 series provides flexible distance extension for existing switch infrastructure without replacing switches. Modular design lets users install fiber only where required, reducing unnecessary expense. Compatible with managed and smart switches, the modules support stable long-distance links suitable for LAN backbone or point-to-point connections.
Key specifications
Product family: TL-SM311 series fiber module cards
Function: extends transmission distance for managed/smart switches
Typical reach: several kilometers to tens of kilometers (model-dependent)
Application: LAN distance extension, point-to-point links, backbone connections
Installation: plug-in module for compatible switches
How to use
Install the TL-SM311 module into the compatible slot of a managed or smart switch according to the switch manufacturer’s instructions. Connect the fiber cable between modules or to other fiber endpoints, verify link indicators and switch configuration, and adjust switch port settings as required for the network. Choose module types and fiber transceivers that match the required distance and fiber type.
Recommendations
Verify compatibility with your switch model and select the specific TL-SM311 variant that matches desired reach and fiber type; follow safety and handling guidelines for fiber optics during installation.
