When would a mid-entry splice in a fiber-optic network be used?

• A. For installing new telephone lines
• B. In a self-healing ring network
• C. During initial network testing
• D. While replacing damaged fibers

Answer: (B)

A mid-entry splice in a fiber-optic network is typically used in a self-healing ring network configuration. In such networks, the primary objective is to create redundancy and ensure continuous service even if a fault occurs somewhere in the network loop. In a self-healing ring, the network utilizes a looping configuration where data can be sent both directions around the ring. This means that if a fiber or a connection fails, the data can be rerouted through the opposite direction, maintaining network integrity. A mid-entry splice allows for connecting additional fibers into the existing network without interrupting the overall service. This capability is crucial in maintaining the functionality of a self-healing ring. While other scenarios might involve fiber splicing, they do not specifically require the unique function of mid-entry splices as employed in self-healing ring designs. For instance, installing new telephone lines typically uses different techniques tailored for copper cabling rather than fiber-optics. Network testing may involve splicing, but it often focuses on testing endpoints rather than inserting splices mid-route. Replacing damaged fibers might not always necessitate a mid-entry splice, as in many cases, a simpler splice at the point of damage might suffice without the need for the mid-entry configuration.
