英文摘要 | A light source (610) comprising a source of radiation such as a single-electrode distributed feedback semiconductor laser diode is frequency modulated by direct current modulation with no pre-equalization or pre-distortion of the signal, and the optical signal is coupled to and carried by an optical fiber (622) to a remote location. At the remote location, an optical discriminator (626) such as a fiber Fabry-Perot interferometer can be used for both channel selection where more than one channel is being carried by the optical fiber and for covering the frequency modulation signal of each channel to an amplitude modulated signal. The amplitude modulated signal can be detected by a direct detection receiver (628). In those instances where signal enhancement is required, such as in long-haul lightwave transmission systems, an optical amplifier (624) can be substituted for the normally mandatory regenerator located at the repeater stations. |
