Embodiments disclosed herein include receiver optical assemblies (ROAs) having a photo-detector remotely located from a differential transimpedance amplifier (TIA). Related components, circuits, and methods are also disclosed. By providing the photo-detector remotely located from a TIA, additional costs associated with design constraints of providing the photo-detector intimate with a TIA may be avoided, thereby reducing cost of the ROA. In this regard as a non-limiting example, the ROAs according to the embodiments disclosed herein allow shorter haul active optical cable applications for use in consumer applications from a cost standpoint with the added benefits of increased bandwidth and low noise performance of optical fiber. In this regard, the ROAs disclosed herein provide higher input impedance differential TIA circuits and transmission circuits inhibiting or reducing ringing effects and maintain a sufficiently low resistance-capacitance (RC) time constant for differential TIA circuit to allow for higher bandwidth operation of the ROA.
