Unpowered network tap kit to monitor the transmit or the receive of wired LAN communications. The Skinny Network will work with 10/100 Megabit and Gigabit infrastructure and is compatible with Power over Ethernet (PoE).
+Frank Yu You can tap a Gigabit Ethernet line, but a traditional, passive network tap will drop the speed down to 100Mbps. It would take some active electronics to maintain gigabit speed. Gigabit ethernet uses all the conductors on the cable so you just can't pull out the transmit or receive pair. I made a video discussing this topic in a little more detail if you are interested. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2tsvBnTIjFo.html
+Frank Yu I do not know of a way to make a passive Gigabit tap. In a 100M tap you are forcing the transmit or receive side of the data transmission into the receive pair on the network interface card (NIC) on the monitoring computer. A passive Gigabit tap would require you to be able to monitor all 4 pair of the network cabling. The transmit and receive data in a Gigabit system flow in a bidirectional manner on each pair of wires. I'm not sure how you would go about separating the data streams.The only way I know to accomplish tapping a Gigabit system is to intentionally slow it down to 100M speeds, but in that case it's not really a gigabit tap any more. Sorry.
