Classification: CPC G  H | IPC G  H

Claim 0:
1. A pluggable optical module comprising:
an electrical connector configured to connect with a host communication apparatus, the host communication apparatus outputting a data signal and a control signal via the electrical connector;
an optical connector;
an optical light source configured to output a light;
a Mach-Zehnder modulator, including a first optical waveguide and a second optical waveguide, configured to output an optical signal generated by interference between a first light passing through the first optical waveguide and a second light passing through the second optical waveguide; and
a driver configured to drive the modulator based on the data signal, and apply a bias voltage to the modulator, the bias voltage corresponding to a phase difference between the first light and the second light based on an angle indicated by the control signal.
