For friends in the security transmission equipment industry, I believe everyone should be familiar with industrial Ethernet switches. When a customer buys an industrial Ethernet switch, many customers will ask for a switch with several optical and electrical power. Recently, they have received many calls from customers, asking what is the difference between the electrical port and the optical port of the industrial Ethernet switch, and why there are optical ports and optical ports. Is there any difference in the role of electrical ports? Therefore, for these problems of the optical and electrical ports of industrial Ethernet switches, today the editor of Feichang Technology will give you a brief introduction. Let’s take a look!
First of all, we need to understand clearly what is an optical port and an electrical port. The optical port of the industrial Ethernet switch refers to the optical port refers to the optical fiber interface, with specifications such as single-mode, multi-mode, Gigabit, and 100M. The optical ports on industrial switches are generally paired together, one TX sending end and one RX receiving end. The port type of a 100M switch is generally a square port with an SC card, and the optical port of a gigabit switch is generally an SFP optical module. For LC. The electrical port is also the RJ45 port, the port (network cable) plugged into the twisted pair, the general rate is 10M or 100M, which is a 100M industrial switch, and some support 1000M, which is a Gigabit switch.
In fact, the purpose of the optical port and the electrical port of an industrial Ethernet switch are the same, both for transmission. The longest distance of the electrical port is 100 meters, and the optical port can reach 5KM to 100KM depending on the fiber type. Therefore, electricity is generally used in ordinary use, and the corresponding optical fiber is selected for long-distance transmission.
Well, the above content is what Feichang Technology means about the optical and electrical ports of industrial Ethernet switches? The detailed introduction of this issue, through the above introduction, I believe everyone should understand it?
