Difference Between Single Mode And Multimode Fiber Distance

Multimode fiber optic cable.

Difference between single mode and multimode fiber distance.

The difference between multimode and single mode fibers the way in which these two fiber types transmit light eventually led to their separate names. Multimode fiber optic cable has a large diametral core that allows multiple modes of light to propagate. Single mode fiber has a small light carrying core of 8 to 10 microns in diameter. It is usually used for short distance transmissions with led based fiber optic equipment.

Single mode fiber has a core that measures around 5um while the multimode fiber core measures 50um or more. We will see the differences taking into consideration various comparison factors of transmission system such as data rate distance attenuation time to travel and so on. This means that the core to cladding diameter ratio is 9 microns to 125 microns. Generally designed for systems of moderate to long distance e g metro access and long haul networks single mode optical fibers have a small core size 10 µm that permits only one mode or ray of light to be transmitted.

This page on single mode vs multimode fiber describes difference between single mode and multi mode fiber systems the other difference between terms are also provided. Because multimode fiber is thicker it can accommodate more signals for. The main difference between single mode and multimode optical fiber is the size of the core. When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually.

Multimode fiber has a relatively large light carrying core usually 62 5 microns or larger in diameter. There are two basic types of optical fibers single mode and multimode.
