When searching the Internet for network fiber patch cables, We should condider 2 main factors: the transmission distance and the project budget allowance. So dow do I know which fiber optic cable I need?

What is single mode fiber cable? 

Single mode(SM) fiber cable are the best choice for transmitting data over long distances. They are usually used for connections over large areas, such as college campuses and cable television networks. They have a higher bandwidth than multimode cables to deliver up to twice the throughput. Most singlemode cabling is color-coded yellow.

Singlemode cables have a core of 8 to 10 microns. In single mode cables, light travels toward the center of the core in a single wavelength. This focusing of light allows the signal to travel faster and over longer distances without a loss of signal quality than is possible with multimode cabling.



What is multimode fier cable? 

Multi mode(MM) fiber cable are a good choice for transmitting data and voice signals over shorter distances. They are typically used for data and audio/visual applications in local-area networks and connections within buildings. Multimode cables are generally color-coded orange or aqua.

Multimode cables have a core of either 50 or 62.5 microns. In multimode cables, the larger core gathers more light compared to singlemode, and this light reflects off the core and allows more signals to be transmitted. Although more cost-effective than singlemode, multimode cabling does not maintain signal quality over long distances.

It is also important to consider the type of application when deciding whether to use single-mode or multimode fiber. For example, over longer distances, multimode works well for CCTV but not high speed transmissions.

Above all are the main difference between singlemode and multimode fiber optic cables, Hope It will help you to make the right choice on purchaing fiber cables.
