Abstract
An optical transceiver that provides a receiver optical module including a plurality photodiodes (PDs) each biased through internal bias lines, signal lines carrying driving signals to an optical transmitter module, and external bias lines each connected to the internal bias lines. One of the internal bias lines connected to one of the external bias lines arranged closest to the signal lines has a length shorter than lengths of the other internal bias lines so as not to affect EMI noises induced from the signal lines to the other internal bias lines.
