In the SLAC Linear Collider Detector (SLD), as in most high-energy particle detectors, the electromagnetic noise environment is the limiting factor in electronic readout performance.Front-end electronics are particularly susceptible to electromagnetic interference (EMI), and great care has been taken to minimize its effects.The transfer of preprocessed an&g signals from the detector environs, to the remote digital processing electronics, by conventional means (via metal conductors), may ultimately limit the performance of the system.Because it is highly impervious to EMI and ground loops, a fiber-optic medium has been chosen for the transmission of these signals.This paper describes several fiber-optic transmission schemes which satisfy the requirements of the SLD analog data transmission.
