By understanding the optical fiber, we understand that optical fiber transmits signals through light guide. No electricity, not afraid of lightning strikes, no ground protection. According to the transmission mode in the optical fiber, we can be divided into multi -mode fiber and single -mode fiber. For our users, you can remember the origin of multi -mode and single -mode names. Next, the editor of Fei Chang Technology will introduce single -mode fiber and multi -mode fiber in detail. let us see!
Multi -mode fiber: Multi -modular light can be transmitted.
Single -mode optical fiber: Only one mode of light can be transmitted.
Multi -mode optical fiber transmission distance is closer, usually dozens of times of multi -mode optical fiber transmission distance. Single -mode price is generally more expensive than multi -mode fiber.
The advantages of using optical fiber also include:
When the information point transmission distance is greater than 100m, choose to use copper cables. The relay or network equipment and weak electricity must be increased to increase costs and hidden dangers. The use of optical fibers can easily solve this problem.
2. In a specific working environment (such as factories, hospitals, air -conditioning rooms, power rooms, etc.), there are a large number of sources of electromagnetic interference. Fiber can run stably in these environments without being disturbed by electromagnetic interference.
3. The optical fiber has no electromagnetic leakage, and it is difficult to detect the signal transmitted in the fiber. It is a good choice (such as military, research and development, auditing, government and other industries).
4. The environment for bandwidth requires more than 1g, and fiber is a good choice.
In the actual application process, if the distance is far away, the single -mode fiber is used; if the distance is closer, multi -mode fiber can be used. In addition, optical fiber transmission needs to use optical modules. The single -mode optical fiber uses a single -mode optical module, and the multi -mode fiber uses the corresponding multi -mode optical module. Generally speaking, the price of a single -mode light module is higher than the multi -module module.
