Which category of fiber-optic cable design typically uses some variation of the star topology?

The category of fiber-optic cable design that typically utilizes some variation of the star topology is signal distribution. In a star topology, each device or node is individually connected to a central hub or switch, allowing for efficient data management and signal distribution across a network. This configuration is particularly beneficial for signal distribution because it enables the central hub to control and manage the flow of signals between multiple devices without interference.

The central hub can effectively amplify or regenerate signals, making it easier to maintain signal integrity over longer distances, which is crucial in fiber-optic communication. Additionally, if one connection fails or needs maintenance, it does not disrupt the entire network, allowing other devices to continue communicating effectively.

In contrast, data processing, wireless transmission, and power distribution do not typically employ a star topology for their designs. Data processing often requires different configurations that optimize computing resources rather than focusing solely on signal distribution. Wireless transmission utilizes broadcast mechanisms rather than a fixed topology like star, and power distribution typically involves series or parallel configurations to ensure effective distribution of electricity rather than a centralized connection model. Hence, the association of star topology with signal distribution is rooted in its ability to facilitate organized, reliable, and maintainable communication between multiple nodes.
