Analog fiber-optic data

Summary form only given. Analog fiber-optic data transmission is required for many diagnostics at the Pulsed Based Fusion Accelerator (PBFA-Z). Radiation-induced brightness and darkening has been characterized in fiber optic cables located at distances ranging from 5 cm to several meters from the target. Spectral measurements of this noise signal have been made to determine which combination of bandpass filtering and shielding is adequate for the diagnostics.
