What RAY Should I Choose For My Fiber Optic Cable, Single Mode or Multi-Mode?

An Optical Fiber is a thin, flexible, transparent fiber that acts as a "light pipe" to transmit data signals in the form of light from one end to the other. Currently aerospace and communication design engineers are using Fiber Optics for highly reliable, real-time networking, as well as for low-latency, high-throughput signal processing applications. Fiber Optics comes in two different standard applications; Single Mode and Multi-Mode. Both Single Mode and Multi-Mode have particular benefits but are designed to be optimal in two different ways.
Single Mode
Single Mode optical fiber is designed to carry only a single ray of light; this produces more of a direct line.
·         Used for longer distances
·         Smaller core size, typically between 8 and 10µm.
·         Common for telecommunications
Multi-Mode
As light travels through a Multi-Mode fiber optic cable, the light is bounced back and forth towards the ending direction. The bouncing of the rays of light is more suitable for multiple and shorter connections.
·         Larger core size
·         Used for shorter distances, such as within a building.
·         Multi-mode fiber has a higher light-gathering capacity than single mode
It is very important when choosing the correct fiber optic cabling format, that you take into account what capabilities the fiber optic will need to carry out. If the fiber cable is going to be used for long distances, Single Mode is the best choice. If your application requires a shorter distance, that Multi-mode would be most effective. Choosing the correct format is vital to get the most out of your fiber optic investment.
