Talking about the function, classification and working principle of OTG data line

 What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny USB interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being.

OTG to Type-C
The role of OTG is to realize data transfer between mobile devices without a computer. Compared to the one-wire connection of two mobile devices, the devices can be directly connected through the OTG cable for data transmission and printing operations. No need to bring a memory card or computer to transfer. The most common is that the mobile phone is connected to a USB device such as a U disk through an OTG cable, thereby expanding the functions of the mobile device.
OTG data line classification
What is the OTG data cable? Generally, there are two types of OTG cables, one that needs to be connected to the power source, and the other that does not need to be connected to the power source, but their functions are the same, and they are generally used to connect USB external devices, such as printers. Cameras and other equipment. For example, for example, our mobile phone supports OTG function, but we want to play movies or music in the USB flash drive, what should we do? General users can only transfer files on the USB flash drive to the mobile phone through the computer to play, but as long as through the OTG data cable, we can directly play the files on the USB flash drive on the mobile phone.

Usually, the OTG cable we call refers to the OTG data cable. Its function is to realize the direct connection of mobile devices other than computers. It is very popular and practical for today's smart phones and tablet computers. Through the OTG data cable, we can directly connect the mobile phone to a U disk or other USB devices, which greatly facilitates the use of users. The OTG cable is the best bridge.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con
