Can the optical fiber convert the network cable? Optical fiber is a kind of light-guide glass fiber, which transmits optical signals and cannot be directly connected to network cables. It needs to use photoelectric conversion equipment to convert optical signals into network signals. Common photoelectric conversion equipment includes household optical fiber cat equipment, optical fiber transceiver and Optical switch. Next, the editor of Amini Technology will give you a brief introduction. If you are interested, let’s take a look!
1. Household fiber optic cat equipment
The fiber modem is also called the modem. Its main function is to perform signal conversion. It is a relay device for network transmission. The “fiber modem” is generally used for transmission distances exceeding 20KM and speeds exceeding 2M. Optical transmission equipment such as SDH/PDH is required in the middle. In the case of transit, the optical modem is used, which is mainly installed at both ends of the optical fiber, and the transmitted data is converted between electrical and optical signals. When the home is installed with optical broadband, the optical modem should be used to convert the signal to allow computers and other equipment Can recognize these signals, and now the optical modem is a multi-function device integrating telephone, TV, broadband, router, and WiFi.
Optical fiber transceiver is a kind of photoelectric conversion equipment that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It inputs optical signals from optical ports and outputs electrical signals from electrical ports (RJ45 crystal head interface). The process is to convert electrical signals into optical signals and transmit them through optical fibers. At the other end, the optical signals are converted into electrical signals, and then connected to routers, switches and other equipment. According to the transmission distance, they can be divided into single-mode and multi-mode transceivers. ①Single-mode optical fiber transceiver: the transmission distance is 20 kilometers to 120 kilometers; ②Multi-mode optical fiber transceiver: the transmission distance is 2 kilometers to 5 kilometers.
In the transmission process, optical fiber transceivers must be used in pairs, suitable for distances exceeding 100 meters, each indicator light represents a different meaning, 1000-when it is on, it represents 1000M speed, and 100-when it is on, it represents 100M speed; FX—- When it is on, it means that the pigtail is connected, and when it is flashing, it means that data is being transmitted; FX LINK/ACT—when it is on, it means that the Internet cable is connected, and when it is flashing, it means that data is being transmitted; when it is on, it means that the power cord is connected; TX LINK/ACT— -When it is on, it represents the full-duplex rate, and when it is off, it represents the half-duplex.

Three, photoelectric switch
Optical switch is a kind of network transmission relay equipment. The difference between it and ordinary switch is that it uses fiber optic cable as the transmission medium. The network has a very large bandwidth, so the transmission rate is faster and the anti-interference ability is stronger.
There are 2 optical 2 electrical, 4 optical 2 electrical, 8 optical 2 electrical and other photoelectric switches. 4 optical 2 electrical means 4 optical fiber input ports and 2 RJ45 network port output, which can support 100M and Gigabit networks, suitable for Multi-optical fiber transmission for large enterprises.
