Which device converts electrical signals into optical signals for fiber optic networks?

The device that converts electrical signals into optical signals for fiber optic networks is the fiber optic transceiver. This component performs a crucial role in networking by allowing the transmission of data over optical fibers, which is essential for high-speed data communication.

A fiber optic transceiver typically consists of both a transmitter and a receiver. The transmitter converts the electrical data signals generated by devices such as computers or servers into optical signals, which are then sent through the fiber optic cables. The receiver, on the other hand, converts incoming optical signals back into electrical signals that can be processed by network devices.

In the context of fiber optic networks, it is important to have efficient methods of converting these signals to take advantage of the high bandwidth and low loss characteristics that fiber optics provide. The transceiver is specifically designed for this application and is integral to establishing reliable connections over optical networks.

In contrast, options like a fiber optic splitter do not perform signal conversion; rather, they split optical signals to distribute them across multiple outputs. A network switch operates primarily at the electrical signal level, directing traffic within local area networks (LANs) without converting signals. A signal booster amplifies the strength of optical signals but does not convert types of signals. Thus, the fiber optic transceiver stands
