Patent ID: 7734184

Claim:
An optoelectronic transceiver for use in optical communication networks, comprising: a printed circuit board; a receiver optical subassembly; and an active linear transmitter optical subassembly, including a header grounded to a chassis ground upon which circuitry is mounted, the circuitry including: a first input node configured to receive a first data signal; a second input node configured to receive a second data signal that is complementary of the first data signal; a buffer stage having a first node coupled to the first input node and a second node coupled to the second input node; an amplifier stage having a fifth node coupled to a third node of the buffer stage, having a sixth node coupled to a signal ground, wherein the signal ground is not coupled to the header; and an electro-optical transducer having an eighth node coupled to a seventh node of the amplifier stage and having a ninth node configured to be coupled to a voltage source, the electro-optical transducer being coupled to a fourth node of the buffer stage.
