Modem refers to modulator-demodulator . A Modem basically converts the digital signal coming from a computer to analog signals so that these signals could be transmitted through a wire from one computer to other and the modem at the second computer converts the coming analog signals to digital signals so that the information coming through the signals can be stored on other system .
Modems are not needed for fiber optic connections because the signals are transmitted digitally from beginning to end.
