Patent ID: 8693879

Claim:
An optical transceiver module, comprising: a housing; a printed circuit board at least partially included in the housing; a transmitter optical subassembly electrically coupled to the printed circuit board; and a receiver optical subassembly electrically coupled to the printed circuit board, the receiver optical subassembly including an optical receiver package, the optical receiver package including: a package base defining a grounded reference surface; a photodiode configured to receive and convert an optical signal into an electrical signal; a capacitor having a first electrode electrically coupled to a first electrode of the photodiode; a transimpedance amplifier configured to amplify the electrical signal produced by the photodiode, the transimpedance amplifier mounted on the grounded reference surface and being electrically coupled to the photodiode; and an isolator, comprising: a layer of dielectric material mounted on the grounded reference surface; and a metallic layer overlying the layer of dielectric material, the capacitor being affixed and electrically coupled to the metallic layer, and the metallic layer being electrically coupled to a ground of the transimpedance amplifier via a connector that is independent of the grounded reference surface.
