Multimode And Single Mode Fiber Difference

Single mode fiber optic cable has a small diametral core that allows only one mode of light to propagate.

Multimode and single mode fiber difference.

Typical transmission speed and distance limits are 100 mbit s for distances up to 2 km 1 gbit s up to 1000 m and 10 gbit s up to 550 m because of its high capacity and reliability multi mode optical fiber generally is used for backbone applications. Single mode fiber cable systems are usually more expensive even though the actual cost of single mode fiber cable is cheaper than that of multimode fiber cable in the market. The main difference between single mode and multimode optical fiber is the size of the core. 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.

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. Single mode fiber has a core that measures around 5um while the multimode fiber core measures 50um or more. Because multimode fiber is thicker it can accommodate more signals for. Because of this the number of light reflections created as the light passes through the core decreases lowering attenuation and creating the ability for the signal to travel further.

The equipment used for communications over multi mode optical fiber is less expensive than that for single mode optical fiber. Numbers of people have expressed their own opinions. There are two basic types of optical fibers single mode and multimode. This is because it is the optics that dominates the total cost of a network system.
