This blog ETU-LINK takes everyone to understand the difference between optical fiber, copper cable and twisted pair. First of all, let’s understand the twisted pair. The twisted pair is made up of multiple groups of insulated copper wires intertwined. The internal medium of the twisted-pair cable is also copper wire, and the internal transmission is an electrical signal. According to the principle...

Now Gigabit Ethernet has been popularized in a large area, and Gigabit Ethernet switches are also widely used in scenarios such as enterprise networks and optical access networks. Gigabit Ethernet has two types of ports, namely RJ45 and SFP ports. These two ports can support the highest transmission rate of Gigabit, and can also be backward compatible with the transmission rate of 10/100M.   ...
