Radiation-tolerant data links for fusion reactors : from serial electrical data link to parallel optical data link

The future thermonuclear reactor is a complex installation that will require permanent monitoring and frequent maintenance operations. The high-gamma dose rates, the high neutron fluence and other radiochemical hazards call for the use of remote-handled equipment. The radiation acceptance level of the instrumentation data links is therefore a key issue. In this paper, we first review the different approaches considered up to now to address this issue. Then, we discuss the new alternatives brought by the Wavelength Division Multiplexing (WDM) capabilities of fibre optic technology.
