Gigabit L2 Managed Switch Chapter 4 Connection 4.1 Ethernet Port Connect the Ethernet ports of the switch to the network devices by RJ45 cable as the following figure shows. RJ45 Port T2600-28TS RJ45 Cable Figure 4-1 Connecting the RJ45 Port 4.2 SFP Port Figure 4-2 demonstrates the connection of SFP port to an SFP module. SFP Slot T2600-28TS SFP Module Figure 4-2 Inserting the SFP Module Optical fiber Optical fiber can be used as a medium for telecommunication and computer networking. It is especially advantageous for long-distance communications, because light propagates through the fiber with much less attenuation compared to electrical cables. For short distance applications, such as a network in an office building, optical fiber permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less attenuation and are also immune to electromagnetic interference. There is no crosstalk between signals in different cables, and no pickup of environmental noise. SFP Module SFP module are input/output (I/O) devices that plug into a Gigabit Ethernet port, linking the port with a 1000BASE-X fiber-optic network. An SFP module possesses a receiver port (RX) and a transmitter port (TX) that make up one optical interface. To enjoy the required optical reach, users can freely select the 14 Connection
