What is the role of splitters in a fiber-optic communication system?

The role of splitters in a fiber-optic communication system is primarily to divide an optical signal into multiple paths. This function is crucial in various applications, such as in passive optical networks (PONs), where a single optical signal from a central office can be distributed to multiple end users. Splitters allow for efficient utilization of fiber infrastructure by enabling a single source of light to reach multiple destinations without the need for additional active equipment.

By splitting the light signal, these devices contribute to the scalability and cost-effectiveness of fiber-optic networks, facilitating the delivery of services to multiple customers while maintaining signal integrity. The ability to manage multiple outputs from one input makes splitters an essential component in expanding network reach and improving flexibility in network design.
