What is a fiber optic splice used for?

A fiber optic splice is primarily used to join two optical fibers together, which is essential for creating continuous communication paths in fiber optic networks. This process ensures that the light signals can travel seamlessly from one fiber to the next without significant loss of signal strength or quality.

When optical fibers are spliced, they are aligned precisely to minimize misalignment losses and maximize the transmission efficiency. This is particularly crucial in telecommunications, where maintaining signal integrity over long distances is a vital requirement.

In contrast, other options do not accurately describe the function of a fiber optic splice. Enhancing the brightness of light involves different optical components and adjustments, while weakening a signal is generally undesirable in fiber optic systems aimed at high fidelity communication. Lastly, converting light into electrical signals pertains to devices like photodetectors, not splices, which specifically deal with the physical connection between fibers rather than conversion processes.
