Abstract
According to the present disclosure, a controlling unit arbitrarily determines a current set temperature of a temperature setting unit to cause a light generating unit connected to the temperature setting unit to generate an optical signal having a wavelength according to the current set temperature, thereby making it possible to effectively reduce a wavelength overlap phenomenon that may occur when a plurality of R-ONUs in a passive optical network simultaneously transmit the optical signals.
