TP-Link TL-SM301U - 1000M copper module with one RJ45 port.
	• 1000M copper module with one RJ45 port.  • Applied to TL-SL3226P, TL-SL2226P+, TL-SL2226P.
Description  TL-SM301 series Fiber Module Cards are introduced for extending transfer distance, attached to our smart switches. It can extend the distance to several kilometers even tens kilometers which can basically satisfied the distance requirement of LAN. Users can choose whether and which items to use the fiber modules according to the demand in order to low the cost.  There are many kinds of fiber modules. Based on port type, the fiber modules can be divided as the following kinds: Model Description and Connector Max.
