Abstract:
An optical receiver is configured so as to be as less susceptible to noise as possible even in the case where high noise occurs inside an optical transceiver. The optical receiver includes a connection part that connects two photodiodes (PDs) constituting a dual photodiode and a transimpedance amplifier (TIA), wherein signal lines from the dual photodiode are surrounded by a conductor pattern that is not connected to each of the signal lines for each channel, and the conductor pattern is connected to a ground pattern on the transimpedance amplifier or a power source pattern for the PDs.

Claim (Index 4):
The optical receiver according to  claim 1 , wherein:\n the two PDs constituting the dual photodiode are connected with their cathodes facing each other, a connecting point of the cathodes being connected to a PD power source pattern on the TIA chip; from two anodes of the two PDs, two signal lines are drawn out and are inputted into the TIA chip; from the cathode connecting point, the conductor pattern is branched so as to surround the two PDs toward circumferential sides of the PD chip via a capacitor, and the branched patterns are drawn out as two ground patterns from positions sandwiching the two signal lines and are connected to ground patterns on the TIA chip; and the PD power source pattern on the TIA chip is grounded at a high frequency with a capacitor on the TIA chip.
