Transmission of fast signals via optical fibres

Michael Daniel, Durham University

For the current and next generation Cherenkov telescope facilities,
transmitting signals over optical fibres offers many advantages in
comparison to coaxial cable, which give greater attenuation and
dispersion to the short fast pulses of Cherenkov light. Optical fibres
do not experience cross talk, are isolated from grounding problems and
reduce the risk of damage due to lightning strikes. They are also
applicable to intensity interferometry as a means of bringing signals
from individual pixels in multiple telescopes to a central location.
This talk will summarise some of the presently used optical fibre
solutions and the possible future enhancements.
