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 cross-
talk 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

Connection
Connect the Ethernet ports of the switch to the network devices by RJ45 cable as the
following figure shows.
