Abstract
An object is to output an optical signal accurately corresponding to a data signal. A pluggable optical module () includes a pluggable electric connector (), a control unit (), an optical signal output unit (), and a pluggable optical receptor (). The pluggable electric connector () can communicate a modulation signal (MOD) and a control signal (CON) with an optical communication apparatus (). The optical signal output unit () outputs an optical signal (LS) modulated by the modulation scheme by the control signal (CON) in response to the modulation signal (MOD). The pluggable optical receptor () is configured in such a manner that an optical fiber () is insertable into and removable from the pluggable optical receptor (). The pluggable optical receptor () can output the optical signal (LS) output from the optical signal output unit (). The control unit () controls the optical signal output unit () to output the optical signal (LS) of a modulation amplitude set corresponding to the modulation signal (MOD) in the modulation scheme specified by the control signal (CON).
