Difference Between Single Mode And Multimode Fiber Distance

Single mode fiber is usually 9 125 in construction.

Difference between single mode and multimode fiber distance.

There are two basic types of optical fibers single mode and multimode. 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. When making a decision between single mode and multimode fiber cables the first factor to consider is the fiber distance which you need actually. For example in a data center multimode fiber cables are enough for the distance of 300 400 meters.

The main difference between single mode and multimode optical fiber is the size of the core. Multimode fiber has a relatively large light carrying core usually 62 5 microns or larger in diameter. It is usually used for short distance transmissions with led based fiber optic equipment. 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. This means that the core to cladding diameter ratio is 9 microns to 125 microns. Single mode fiber has a small light carrying core of 8 to 10 microns in diameter. 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.

What is the difference between multimode and single mode fiber. Single mode fiber has a core that measures around 5um while the multimode fiber core measures 50um or more.
