The optical port and electrical port of the industrial switch
For friends in the security transmission equipment industry, I believe everyone should be familiar with industrial Ethernet switches. When customers purchase industrial Ethernet switches, many customers will ask for switch , which is a few optical and electrical switches. Recently, they have received calls from many customers, asking about the difference between the electrical port and the optical port of the industrial Ethernet switch, why is there a difference between the optical port and the electrical port? Are their functions different? Therefore, today we will briefly introduce them to you.
First of all, we need to understand clearly what optical ports and electrical ports are. The optical port of an industrial Ethernet switch refers to the optical port, which refers to the optical fiber interface, and has single-mode, multi-mode, gigabit, 100-megabit and other specifications. The optical ports on industrial switches are generally paired together, one TX transmitter and one RX receiver. The port type of the 100-megabit switch is generally the SC card assembly port, and the Gigabit switch optical port is generally the SFP optical module, and the port type is LC. The electric port is also the RJ45 port. The port (network cable) that plugs into twisted pair . The general speed is 10M or 100M, which is a 100M industrial switch. Partly supports 1000M, which is a gigabit switch.
In fact, the optical port and electrical port of industrial Ethernet switches are the same, and they both play a transmission role. The maximum distance between electrical port and is 100 meters, and the optical port can reach up to 120KM depending on the fiber type. Therefore, when using it normally, electricity is generally used, and the corresponding optical fiber will be selected when conducting long-distance transmission. What do the optical port and electrical port of
industrial switch mean? Through the above introduction, I believe everyone should be able to understand it, right? If you still don’t know anything, you are welcome to consult anywhere.
