Abstract
An optical signal receiving apparatus included in an optical line terminal (OLT) includes a resistor disposed between a capacitor connected to a receiving optical sub-assembly (ROSA) and a limiting amplifier, wherein a resistance value of the resistor may be determined based on the OLT receives an optical signal from an optical network unit (ONU) and whether the ONU transmitting the optical signal to the OLT is switched, the resistance value of the resistor may be determined to reduce a data loss occurring from the optical signal receiving apparatus in response to the OLT receiving the optical signal from the ONU, and the resistance value of the resistor may be determined such that the optical signal receiving apparatus more rapidly follows a change in intensity of the optical signal in response to the ONU transmitting the optical signal to the OLT being switched.
