HFAN-03.2.0: Improving Noise Rejection of a PIN-TIA ROSA

Abstract: For successful optical transceiver design, it is essential to maintain a good immunity between the Receiver Optical Sub-Assembly (ROSA) and external noise sources including the transmitter. This application note will address how the electronic elements should be positioned and assembled on a TO header by studying how the noise can be picked up by the components in the ROSA, with the goal of optimized noise rejection performance.
