The Cisco GLC-T is a Small Form-Factor Pluggable or SFP. It is a type of device that is used to plug into the port of a Gigabit Ethernet. This will then link the port that it is plugged into to the network. This and other Cisco SFPs are great for any business due to the interchangeability of them. They can easily be used in a variety of Cisco products. Depending on the port, they can be plugged into the port of 1000BASE-T, 1000BASE-LX/LH, 1000BASE-SX, 1000BASE-BX10-D/U, 1000BASE-ZX, and 1000BASE-EX.
Within any company, it is important to make sure that data and information can be easily stored and accessed by multiple people. This is not possible if each person is working on their own computer without somehow linking the computers. There are other pieces of equipment that are needed in order to make it possible and will come together to form a network. There are several pieces that are necessary in order to achieve this, such as a network card, Ethernet interfaces, and Cisco GLC-T and SFP transceiver modules.
