TP-Link's TL-SM311 series Fibre Module Cards are designed for extending transfer distance between managed switches, media converters and other TP Link products such as the Smart PoE+ Switch, Web Smart Switch and the JetStream Stackable Managed Switch. When attached to TP-Link's managed/smart switches, they can extend the distance to several kilometres even tens of kilometres which will satisfy the distance requirement of LAN. Users can choose whether and which items to use the fibre modules according to the demand in order to lower cost.
