Does Huawei Switch Support Single-mode Or Multi-mode With Its 53.2 Million Mbps Optical Port?

Simply put, light is connected to light and electricity is connected to electricity. For example, most computer network cards have electrical ports, so they need to be connected to the switch electrical port using a regular twisted pair cable. If both switches have optical ports, or if your computer has an optical network card, you can use optical ports for interconnection, of course, using optical cables in the middle. If two devices are close together, they can be directly connected using optical jumpers. Of course, the production of optical connectors is quite complicated and requires expensive tools, so they are all purchased ready-made. Their appearance is mostly LC now, and older switches have SC. Long distance connection requires fiber optic cable laying and the production of optical distribution boxes at both ends. Then connect to the device with an optical jumper. The interface shapes on the optical distribution box are generally ST and FC. When purchasing optical jumpers, it is important to distinguish the external types of the ports on both sides. The bandwidth of a general optical port is generally over 1000M, while the majority of electric ports are 100M. Of course, many laptops currently have electric port network cards with a bandwidth of 1000M. The connection of the electrical port is relatively simple, and most of them are RJ45 standard modules. The optical port needs to consider the matching of modules and optical cables, as well as the matching of optical modules at both ends, so the so-called optical port on general equipment is actually just a base that can be inserted into modules. The base can be equipped with plug-in modules, multi-mode optical modules, and single-mode optical modules. According to the bandwidth support of the switch for this base port, it can be further divided into 100M, 1000M, 10000M, and so on. The most important thing is that the module types on both ends should be consistent. The types here mainly refer to three factors: multiple/single mode, bandwidth, and distance.
