What are the two main types of fiber optic cables?

The two main types of fiber optic cables are single-mode and multi-mode. Single-mode fiber optic cables have a small core diameter, allowing only one mode of light to propagate. This design minimizes signal attenuation and enables long-distance data transmission, making single-mode fiber ideal for applications requiring high bandwidth over greater distances. It is typically used in telecommunications and long-haul data connections.

In contrast, multi-mode fiber optic cables have a larger core diameter, permitting multiple modes of light to travel simultaneously. This allows for the transmission of data over shorter distances while maintaining a good level of bandwidth. Multi-mode fibers are commonly utilized in local area networks (LANs) or within a building where the distances are not excessively long.

Understanding these two types is crucial for determining the appropriate fiber optic solution based on distance, bandwidth needs, and application requirements in network installations.
