What is the primary purpose of using a splitter in a fiber-optic network?

The primary purpose of using a splitter in a fiber-optic network is to divide the signal to multiple outputs. In fiber optics, a splitter is a passive optical device that takes a single input signal and distributes it into multiple output signals. This function is essential in applications such as fiber-to-the-home (FTTH) deployments, where a single optical signal from a central office can be split to serve multiple users or homes within the same area.

Using a splitter allows for more efficient use of the optical fiber infrastructure, as it enables a single fiber link to branch out to several locations without the need for additional fibers. This not only reduces costs but also simplifies the network design. The split ratio can vary depending on network requirements, allowing flexibility in how many connections can be made from a single fiber feed.

Other options, while related to signal management, do not accurately describe the primary function of a splitter. Increasing signal strength involves optical amplification, which is handled by different devices such as optical amplifiers. Similarly, switching between different networks is achieved through other network equipment designed for routing and switching, rather than by the splitting functionality provided by the splitter.
