What is the primary function of a fiber optic coupler?

The primary function of a fiber optic coupler is to combine or split fiber optic signals. Couplers are essential components in fiber optic networks as they allow for the distribution of optical signals to multiple fibers or the merging of signals from multiple fibers into a single output. This capability is critical in various applications, such as network routing, signal splitting for multiple users, and combining signals from different sources.

In practice, couplers can be used in a range of configurations, including 1x2, 2x2, and more complex arrangements, allowing for flexibility when designing and deploying fiber optic networks. The ability to efficiently manage optical signals facilitates scalability and enhances the overall performance of the network. Understanding the role of couplers is crucial for anyone working with fiber optics, as they are integral to the functionality of optical communication systems.
