no it doesnt need a special cable neither does it need another gigabit port to connect to
it simply means it supports gigabit speeds ... and u need ur network to support such speeds which can be achieved by cables like cat 5e, cat6, cat7
what we use is cat5
ofcourse this cable will work too
but with a rated max connection speed of 100mbps
its just another lan card on ur pc ... just a regular NIC no worries
