Abstract
An optical transceiver includes a printed circuit board (PCB) with an edge; one or more first components associated with a transmitter functionality of the optical transceiver, the one or more first components including a linear driver component and a processing component; one or more second components associated with a receiver functionality of the optical transceiver, the one or more second components including a linear transimpedance amplifier (TIA) component; electrical contacts arranged at the edge of the PCB; first electrical traces, connected between the one or more first components and the electrical contacts; and second electrical traces, connected between the one or more second components and the electrical contacts. The one or more first components are closer to the electrical contacts than the one or more second components.
