Usually, there is a laser diode that is optically coupled to the fiber.

To contact with the remote persons
WDM wavelength division multiplexing
In wired systems the transmitter-receiver pair is commonly referred to as a modem (modulator/demodulator); in wireless systems the terms transmitter and receiver continue to be used; and for fiber-optic cable systems the terms electrical-to-optical (E/O) and optical-to-electrical (O/E) interfaces are used to describe the transmitter-receiver pair

The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
