Multimode fiber cable is a type of fiber optic cable that transmits multiple modes, or paths, of light along its core. It is one of the most common types of fiber optic cable used for communications and is designed to transmit data over longer distances, making it ideal for use in a variety of applications.
Multimode fiber cables typically have larger cores than single-mode cables, allowing multiple modes of light to be transmitted simultaneously. This is because the larger core size allows the light to travel further before it is scattered, resulting in less attenuation of the signal and longer transmission distances. Multimode cables are also more cost-effective than single-mode cables, making them a popular choice for many applications.
Multimode fiber cables typically come in two standard core sizes – 62.5/125 (OM1) and 50/125 (OM2). The OM1 cables are typically used for short distance applications, such as connecting two buildings on a single campus, while the OM2 cables are designed for longer distance transmissions, such as connecting two cities or countries.
When using multimode fiber cables, it is important to ensure that the cables being used are compatible with the equipment being used. For example, an OM2 cable may not be compatible with an OM1 device, or vice versa. Additionally, the type of light source being used must match the type of fiber optic cable being used. For example, if an LED light source is used, then an OM1 fiber cable should be used, while an OM2 fiber cable should be used if a laser light source is used.
In conclusion, multimode fiber cables are an ideal choice for a variety of applications, as they are capable of transmitting multiple modes of light over long distances. They are also more cost-effective than single-mode cables, making them a popular option.
