Which device connects two wires together in a fiber optic setup?

The correct response pertains to the function of a connector mating adapter in a fiber optic setup, which is designed to connect two optical fibers or wires together. This device facilitates the physical and optical alignment of fiber ends, ensuring that light can pass from one fiber to another seamlessly. A well-designed connector mating adapter minimizes signal loss and reflects light properly, allowing for efficient data transmission.

In fiber optic systems, maintaining low attenuation and reducing the effects of misalignment or loss due to imperfect connections is crucial. The connector mating adapter achieves this by having a precise alignment mechanism, often featuring ferrules that hold the fiber ends in place and ensure they are close enough for optimal light transfer.

In contrast, other options serve different purposes. A launch cable can be used for signal testing or providing a clean light input but does not directly connect two fibers. A visual fault locator is a diagnostic tool that identifies breaks or faults in fiber, while a power meter measures the power of light in optical fibers or networks, which helps assess performance but does not connect fibers themselves. Thus, the connector mating adapter is the essential component for connecting two wires in a fiber optic installation.
