Say goodbye to not knowing how to pretend, and communicate easily with the great god. Novice Xiaobai can understand the difference between single-mode fiber and multi-mode fiber
Optical communication single-mode fiber & multi-mode fiber difference OPTICOMBINE
Introduction-----Problems arise.
Many friends who are new to optical communication are eager to learn about optical communication, but they were born in non-major classes and did not study science, or you have never been exposed to optical communication information industry before. Look at defeat by ignorant terminology. If this is the case, you happen to read this article, then I am honored to tell you that you are lucky, someone understands you like this (that is, the super user-friendly OPTICOMBINE) and will do it for you Take the time and energy to learn the knowledge of optical communication, and then convert it into easy-to-understand text, a language that even junior high school students can understand and understand. Let's learn with Opticombine. COME ON!
Text-------Solving the problem
Today's first lesson is the most common and basic knowledge-----------
When it comes to optical fiber , there is no need to think about it as complicated, just imagine it as Electricity, just a little conversion. What is the most basic of electricity? wire. Similarly, the most basic optics in optical communication is "light", but there is a better name fiber. At present, there are two main materials for optical fibers on the market, one is plastic optical fiber and the other is quartz optical fiber, which is also called glass optical fiber. , Because the main ingredient is silica. This (1) light (3) fiber (9) capacity (8) easy (9) large (2) gauge (7) model (3) produced (6) produced, so (3) is cheaper with (0), However, its core is relatively brittle and easy to break, and its inner core diameter cannot be as small as a silica fiber, which can reach the micron level. In order to ensure the quality of optical signal transmission, like the transmission signal, it is definitely hoped that the information received by the receiving end and the information sent by the sending end are the same or the difference is as small as possible. That is, the transmission dispersion is not desired (especially in long-distance transmission). Obviously, plastic optical fiber cannot meet this requirement. Therefore, the most common and most widely used optical fibers on the market are generally quartz optical fibers.
Conclusion and forecast ------ Please stay tuned.
Since plastic optical fiber has so many shortcomings, are there any shortcomings in quartz optical fiber when transmitting signals? Must be perfect? After further understanding with Changjia, who has been specialized in optical fiber production for more than ten years, after personal experience in the factory, I found that different quartz optical fibers are very different. What is the specific situation? Next time OPTICOMBINE personally announced
