Which of the following describes the process of splicing optical fibers?

The process of splicing optical fibers involves connecting two fibers by aligning and fusing them together. This fusion process is crucial because it ensures minimal loss of signal strength and degradation of the optical signal that could occur at the junction of the fibers. The precise alignment of the fiber cores during splicing allows for efficient light transfer between the two fibers, resulting in an effective and reliable connection. Splicing can be done through different methods, such as fusion splicing and mechanical splicing, but the fundamental principle remains the same: creating a seamless connection that maintains the integrity of the optical signal.

In contrast, joining two cables together using mechanical clamps, while it might hold fibers in place, does not achieve the same level of signal integrity. Similarly, separating fibers to minimize loss is not a splicing action, as it quite literally moves them apart rather than joining them. Attaching protective coverings around fiber ends is an important practice for safeguarding the fibers but does not fall under the definition of splicing either. Thus, the correct process for splicing, which is to align and fuse the fibers, makes B the accurate choice.
