There are three types of Cisco gigabit electrical port: GLC-T, GLC-TE and SFP-GE-T. They are all RJ45 interface, the transmission distance is 100m, it is a kind of cost savings of gigabit Ethernet connection solution, such as the data center, access, storage area network applications, so the three types of products are often difficult to distinguish. So what are their difference? Please follow ETU...
