TRANSMISSION APPARATUS AND METHOD FOR CONFIRMING CONNECTION OF OPTICAL FIBER

摘要

There is provided a transmission apparatus, which includes: a filter configured to pass an optical signal having a predetermined wavelength received via an optical fiber, a variable optical attenuator configured to attenuate a power level of the optical signal passed by the filter, a first measuring circuit configured to measure a first power of the optical signal before being passed by the filter, a second measuring circuit configured to measure a second power of the optical signal attenuated by the variable optical attenuator, a detector configured to detect a difference between the first power and the second power, and a controller configured to increase an attenuation factor of the variable optical attenuator when the difference is equal to or larger than a first predetermined value.
