A seed light module based on a single longitudinal mode oscillation light source is provided. The seed light module includes a multi-wavelength signal generation light source unit generating a continuous wave (CW) of different wavelengths, a multiplexer wavelength-division multiplexing the light output from the light source unit, a polarization beam splitter splitting the light of multiple wavelength components output from the multiplexer according to specific polarization components, phase modulators phase-modulating signals of a first polarization component and a second polarization component split by the polarization beam splitter onto a sine wave having a frequency and amplitude, a radio frequency (RF) signal generator generating the sine wave, a RF signal distributor distributing the generated RF signal, amplifiers amplifying the distributed RF signals, and a polarization beam combiner combining the lights phase-modulated by the respective phase modulators and providing the combined light as a seed light output.
