The fully assembled and enclosed brother to the Throwing Star LAN Tap Kit. The pro model sports all of the same 10BASET and 100BASETX monitoring goodness ready to go in your kit bag, no soldering necessary.
To a target network this little guy looks just like a stretch of cable. Requiring no power to operate the passive tap provides RX and TX monitoring capabilities for your favorite packet sniffing programs (e.g. tcpdump, tshark, wireshark).
While a gigabit network may not be passively tapped, the Throwing Star LAN Tap Pro features two specially placed capacitors which force 1000BASET networks to negotiate at lower speeds, typically 100BASETX transparently to the end user.
