1. A low-noise sensor system comprising:
an optical sensor having emitters for transmitting optical radiation into a blood-perfused tissue site and detectors responsive to optical radiation after attenuation by pulsatile blood flow within the tissue site so as to generate sensor signals;
a sensor controller having an optically-isolated front-end that receives and digitizes the sensor signals, the sensor controller housed within the optical sensor; and
a serializer in communications with a shielded conductor so as to serially transmit the digitized sensor signals to an external monitor for deriving blood-related physiological parameters responsive to detector signals from the detector, the serializer housed within the optical sensor.
