Abstract
An optical receiver module may include a demultiplexer routing a plurality of multiplexed optical signals to different optical paths depending on their wavelengths, a photodetector provided spaced apart from the demultiplexer to convert the optical signals into electric signals, respectively, a pre-amplifier electrically connected to the photodetector to amplify intensities of the electric signals, a flexible printed circuit board including a first electrode layer, which is electrically connected to the pre-amplifier to transmit the electric signals to the external circuit, and a second electrode layer configured to supply a ground potential. The flexible printed circuit board are provided not to have any via hole between the first and second electrode layers.
