What is the difference between single -mode light module and multi -module module.sfp fiber optic transceivers manufacturer

With the high -speed development of data centers and 5G, the light module has gradually been well known by more and more people, and it has also lost its universal use. We all know that the light module can be distinguished according to the parameter type, such as the single -mode light module and multi -mode light module we often mention. Do you know what does the single -mode and multi -mode discrimination in the single -mode light module and multi -module module mean? What are the differences between the single -mode light module and the multi -module module? How to choose in different use conditions? This article will tell you in detail about the difference between the two and how to choose the results. You can look at it with questions. What is a single -mode light module and multi -mode light module? The optical module is divided into single -mode optical modules and multi -mode light modules based on the applicable type of optical fiber type. The optical fiber wavelength of the single -mode light module is 1310Nm, 1550Nm, and WDM wavelength. The second is the main wavelength of 850nm fiber. Single -mode light modules and multi -module modules in multi -module refer to the transmission method of optical fiber in the optical module. Therefore, they are used with demand with single -mode fiber and multi -mode fiber. The multi -mode optical fiber diameter is 50/125 μm or 62.5/125 μm. The difference between the single -mode light module and the multi -mode light module. In fact, the single -mode light module and the multi -mode light module are not only different types of fiber types of fiber, but also different in other aspects. The transmission interval of single -mode light module with different optical fiber wavelengths is also different. The single -mode optical module with a optical fiber wavelength of 1310nm is large but scattered in the transmission process. The transmission interval is generally within 40km, while the single -mode optical module with a optical fiber wavelength of 1550nm is small but large in the transmission process. More than 40km, the farthest can be transmitted by 120km without relay. Multi -mode light modules are often used for short interval transmission, and the transmission interval is generally within 300 ~ 500m. The use range is introduced by above that knowing that single -mode light modules are commonly used in networks with long transmission interval and high transmission rates, such as urban area networks, passive optical fiber networks, etc., and multi -mode light modules are often used in short transmission interval and transmission transmission. Low -speed networks, such as data center computer rooms, local area networks, etc. The light sources are different from the light sources used by the multi -mode light module and the multi -mode light module. The light source used by the single -mode light module is the light emitting diode or laser, and the light source used by the multi -mode light module is LD or LED. The power consumption of power consumption single -module modules is generally larger than the power consumption of multi -module modules, but the power consumption of the light module is always resolved by the parameters, models and brands of the optical module, so different parameters, models and brands The single multi -mode light module also has the opposite situation. Compared with the multi -mode light module, the number of devices used by single -mode light modules is large, and the laser light source used is more expensive. Therefore, the price of the single -mode light module is higher than the price of the multi -mode light module. How to choose a single -mode light module and multi -module module? The above mentioned that the single -mode light module and the multi -mode light module are different in the transmission interval, the range of use, the use of light sources, power consumption, and price. For example, the urban area network with a long transmission interval should choose a single -mode light module, and the multi -mode light module with a short transmission interval is becoming more and more appropriate. Complex, in a network environment with large nodes, multiple joints, curves, and connectors and couplers, the multi -module module should be selected in a large amount of metering, and a single -mode light module should be selected in the long -distance branch line. Although the single -mode light module and multi -mode light module use the rare question and answer, although the concepts and differences between the single -mode light module and the multi -mode light module have been clarified in detail, there are still many users who have doubts about their use. The three major doubts of the user: Can a single -mode light module connecting multi -mode fiber? For short interval transmission, it can be connected. When the single -mode optical module and multi -mode fiber are connected, the fiber optic fiber stopped transmission in a multi -mode mode in the single -mode optical module. Therefore, it is recommended that the single -mode optical module is very good to connect the single -mode fiber, and try not to connect the multi -mode fiber. Can the multi -mode light module connecting single -mode fiber? Multi -mode light modules cannot connect single -mode fiber, because not only large loss will occur, but even can not communicate. Due to the large lithography of the multi -mode light module, the small diameter of the single -mode optical fiber is small, and the farther the transmission interval, the greater the attenuation of the signal. The signal that the signal can be attenuated before the transmission interval. Can single -mode light modules and multi -module modules be mixed? In fact, when the single -mode light module and the multi -mode light module signal can be accepted by the acceptor, and the light power can be mixed within the acceptance range, such as 100M LX single -mode light module and 100M FX multi -mode light module are It can be mixed, because they can accept signals each other and accept the light power in the opposite range. However, it is not recommended to use this light module above 1G. Since the wavelength of the multi -mode light module of more than 1G is mainly 850nm, there are too many matters to pay attention to when using. Summarizing the above opinion, believe that you should have understood the single -mode light module and multi -mode light module. In order to prevent the formation of link problems, it is recommended that when choosing a single -mode light module and multi -mode light module, you still need to determine according to the use of your practice. The mold light module stops mixed.
