The TL-SM311 Series fiber optic module cards were introduced to extend the transmission distance of your Managed/Websmart switches. These can extend the distance by several kilometers, even by several dozen kilometers, which can basically cover the distance requirements of the LAN. Users can choose if and which elements the fibre modules should use to reduce costs. With the TL-SM311LM MiniGBIC module from TP-LINK, you can add a high-performance port to your TP-LINK switch. With the MiniGBIC connector you can connect two switches and bridge up to 550 m without loss of quality.
