Which optical fiber properties can help reduce connection loss in short-distance systems?

The correct answer centers around the concept that larger fiber cores and higher numerical aperture (NA) can effectively reduce connection loss in short-distance optical fiber systems. A larger core diameter allows more light to enter and be transmitted through the fiber, which enhances the overall efficiency of light transmission. This is particularly beneficial in short-distance applications where maintaining signal integrity and minimizing loss are crucial.

A higher numerical aperture indicates a greater light-gathering ability of the fiber. This means that the fiber can accept light at wider angles, ensuring that even light that would typically be lost due to misalignment or issues in connection is still captured and transmitted effectively. In short-distance systems, this is particularly advantageous as it compensates for potential imperfections in alignment and ensures that more of the emitted light effectively reaches the detector at the other end of the fiber.

Together, a larger core and a higher NA create conditions that favor better performance by minimizing loss through enhanced acceptance of light, thereby optimizing the efficiency for short-distance optical transmission applications.
