Abstract
An optical transmitter includes a semiconductor laser which is supplied with a frequency modulated current. An emitted light from the semiconductor laser is modulated in intensity by an intensity modulator in accordance with an information signal and becomes a signal light pulse. The spectral width .DELTA..nu..sub.m of the light and a power P.sub.s of the signal light pulse meet the following formulas: ##EQU1## where P.sub.th is a threshold input light power when the stimulated Brillouin scattering begins to occur in the optical fiber in case of no frequency modulation of said light, .DELTA..nu..sub.B is the Brillouin gain bandwidth of the optical fiber, and .DELTA..nu..sub.s is the spectral width of the signal light in case of no frequency modulation of the light.
