Abstract
The present disclosure intends to provide an optical signal from an ONU according to a desired service usage state without using the ONU and an OLT. A simulated signal light generation apparatusaccording to the present disclosure is a simulated signal light generation apparatusfor simulating an uplink signal light generated in an optical network unit (ONU) in a passive optical network (PON), and the apparatus includes a usage state control unitthat sets a service usage state of the ONU, a signal generation unitthat generates an uplink signal frame according to the usage state set by the usage state control unit, and an electrical/optical conversion unitthat converts an electrical signal from the signal generation unitinto an optical signal, and the optical signal from the electrical/optical conversion unitis repeatedly transmitted to an optical fiber core
