Single Mode Fiber Optical Cable VS Multimode Fiber Optical Cable

Both these types of optical fibers have their own attributes and are used as per the specific requirements. But there are distinguishing differences between both types. In the following paragraphs, we will be shedding light on what are the areas that differentiate single-mode and multimode fiber cables.As the name suggests, single-mode optical fiber is built to transmit a single light mode, and multimode fiber is designed to propagate several simultaneous light modes. But the difference between single-mode and multimode fiber does not end there. There is a major difference in their built too. Single Mode Fiber Optical Cable features a 9µm optical core. This eventually helps it with longer transmission distance and higher bandwidth. On the other hand, the optical core in a Multimode Fiber Optical Cable measures at 50µm.

 

When it comes to bandwidth, both optical fiber types function differently. Single Mode Fiber Optical Cable uses strong and brighter light sources with lower attenuation. At the same time, it can deliver unlimited bandwidth, making it a preferred choice in this high-paced world.

As compared to this, Multimode Fiber Optical Cable can transmit multiple light modes. Also, the attenuation is higher, and the brightness is lower. And this is the reason why the bandwidth is limited in Multimode Fiber optical cables. Higher bandwidth is an obvious choice among users who prefer an uninterrupted experience, so the single-mode optical fiber has the upper hand over Multimode Fiber Optical Cable in this regard.
