TP-Link MiniGBIC Module, IEEE 802.3z, CSMA/CD, TCP/IP, 1310nm Wave Length\n\nTP-Link MiniGBIC Module, IEEE 802.3z, CSMA/CD, TCP/IP, 1310nm Wave Length\n\nThe TL-SM311 series Fiber Module Cards are introduced for extending transfer distance, attached to the managed/web smart switches. They can extend the distance to several kilometers even tens of kilometers which can basically satisfy the distance requirement of LAN. Users can choose whether and which items to use the fiber modules according to the demand in order to lower cost.\n\n--Support Full-Duplex\n\n--Plug-and-Play\n\n--LED indicators show the operation state of the fiber module\n\n--Supports Pull-or-Plug with power on switches\n\n--Internal power from switches\n\n--Standards and Protocols \u2013 IEEE 802.3z, CSMA/CD, TCP/IP\n\n--Wave Length \u2013 1310nm\n\n--Power Supply \u2013 3.3V\n\n--Fiber Type \u2013 9/125 um Single-mode\n\n--Data Rate \u2013 1.25Gbps\n\n \n\nShipping\n\n--We check all items before sending out.
