The most common type of fiber optic cable is OM1 fiber. 
OM1 stands for "Optical Multimode 1." 
It is widely used in local area networks (LANs) and private networks. 
Here are some key characteristics of OM1 fiber:Core Diameter: OM1 fiber has a core diameter of 62.5 microns (um). 
The core is the central part of the fiber through which light travels.
lData Rates: OM1 fiber can support data rates of up to 1 gigabit per second (Gbps) at distances of 300 meters when using an 850nm wavelength. 
This makes it suitable for many highspeed networking applications.
Jacket Color: OM1 cables are often identified by their orange jacket color. 
The jacket provides protection to the fiber strands inside.
OM1 fiber is a versatile and commonly used choice for various network setups. 
However, it's worth noting that there are other types of fiber optic cables with different characteristics, such as OM2, OM3, and OM4, which offer enhanced performance for specific applications and longer distances. 
The choice of fiber optic cable type depends on the specific requirements of the network and the data transmission needs.
