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

Star topology, commonly associated with fiber-optic cable design, is characterized by a central hub or switch to which all the other nodes or devices are connected. In the context of signal distribution, this design allows for efficient management and routing of data signals. The central hub can serve as a point for signal processing and distribution, ensuring that each node has a dedicated connection to the hub. This setup optimizes performance because if one connection fails, the rest of the network can continue to function without interruption, which is a significant advantage for maintaining reliable data communications.

In contrast, ring topology connects nodes in a circular layout, where each node is connected to two others, forming a loop. This design does not inherently provide the same level of flexibility as star topology for signal distribution. Bus topology utilizes a single backbone cable to which all nodes are connected, making it less efficient in terms of performance and fault tolerance. Point-to-point design establishes a direct connection between two endpoints, which is useful for specific applications but does not involve the broader signal distribution capabilities of star topology.

Thus, the classification of fiber-optic cable design that typically involves star topology is directly related to its effectiveness in distributing signals efficiently through a centralized hub, supporting active network management and enhancing reliability.
