What are the 2 main types of fiber optic cables?

Fiber optic connectors and cables are present in nearly every communication item we may sell, whether it is a DAS installation or a base station with wireless backhaul, you can be sure that fiber optic patch cords and cables are being used somewhere in that network.

Types of Fiber Optic Cables


Multimode fiber and single-mode fiber are the two main types of fiber optic cable.



Single mode fiber


Due to the smaller diameter of the glass core, single-mode fiber can be used for longer distances. A smaller diameter reduces the likelihood of attenuation, ie a decrease in signal strength. Smaller openings isolate the light into a single beam, providing a more direct path and allowing the signal to travel greater distances.



Single-mode fiber also has a much higher bandwidth than multimode fiber. The light source for single-mode fiber is usually a laser. Single-mode fiber is usually more expensive because it requires precise calculations to lase in smaller openings.

Multimode fiber


Multimode fiber is used for shorter distances because the larger opening in the core allows the light signal to bounce and reflect more along the way. The larger diameter allows multiple pulses of light to be sent through the cable at once, thereby transferring more data. However, this also means that there is a greater chance of signal loss, reduction or interference. Multimode fiber typically uses LEDs to generate light pulses.
