The difference between single -mode and multi -mode light module?

The rapid development of the optical communication and data center industry has also been widely used in light modules.

Nowadays, there are many types of optical modules in the market. How can customers make effective selection according to their own needs, so as to accurately purchase their favorite products?

For example, the difference between the single and multi -mode among them is the difference between the two?

First of all, their wavelengths are different. Under normal circumstances, the transmission distance of the multi -module is below 2km; the transmission distance of the single module is above 2km.

The first is the different scope of application. The multi -mode light module is generally a network with a relatively low transmission rate and a relatively short transmission distance; the single -mode light module is used in lines with long transmission distance and relatively high transmission rate.

The second is that the device used in different single -modal light modules is twice the multi -mode light module, so the overall cost of the single -mode light module is much higher than the multi -module module.

The third is the different light sources. The light source of the single -mode light module is the LED with a narrow LD or a narrow spectrum line. The light source of the multi -module module is a light -emitting diode or laser.

Finally, the transmission distance is often used for long -distance transmission at different single -modal light modules; multi -module modules are used in short -range transmission.
