Patent ID: 7657185

Claim:
A transceiver system, comprising: a transmitter portion arranged on a contiguous bottom layer of a multi-layer printed circuit board, the transmitter portion capable of providing signals to a transmitter optical subassembly configured to transmit optical signals from the transceiver system; a receiver portion arranged on the contiguous bottom layer of the multi-layer printed circuit board, the receiver portion capable of receiving signals from a receiver optical subassembly configured to receive optical signals into the transceiver system; a high-voltage power supply arranged on a top layer of the multi-layer printed circuit board, the high-voltage power supply providing a bias voltage for the receiver optical subassembly; and a metallic ground plane arranged on a first intermediate layer of the multi-layer printed circuit board between the top layer and the contiguous bottom layer, the metallic ground plane providing electrical shielding between the high-voltage power supply and the transmitter portion and the receiver portion.
