Hybrid passive optical network |
| abstract |
A hybrid passive optical network system is disclosed. The hybrid passive optical network system includes a fiber line terminating device and an optical network unit in a network structure in which a wavelength division multiplexing method and an orthogonal frequency division multiplexing method are mixed. Here, the optical line terminator and the optical network unit transmit signals through a wavelength recycling method using a seed light source and a reflection type modulator, and the light sources include a seed light source having a single wavelength, a seed light source having two different wavelength bands, And may be a wavelength variable light source. |
