Abstract
A pluggable electric connector is configured to be insertable into and removable from an optical communication apparatus. An optical output module outputs an optical signal and a local oscillation light. An optical reception module outputs a communication data signal generated by demodulating using the local oscillation light. A pluggable optical receptor is configured in such a manner that optical fibers are insertable thereinto and removable therefrom. A first optical fiber is connected between the optical output module and the pluggable optical receptor. A second optical fiber is connected between the optical output module and the optical reception module. A third optical fiber is connected between the optical reception module and the pluggable optical receptor. Optical fiber housing means winds extra lengths of the first to third optical fibers around a guide.
