The fibres used for the readout of the upgraded LHC detectors for the High Luminosity Large Hadron Collider (HL-LHC) will be exposed to very high radiation doses of up to ∼ 500 kGy(Si). From DC measurements of the radiation induced absorption, several singlemode (SM) and multimode (MM) fibres have been qualified. The effect of radiation damage on fibres is also expected to have an adverse impact on the fibre bandwidth. This paper explains the theoretical reasons for this and presents results of extensive tests to determine the significance of this effect for one of the previously qualified radiation-hard multi-mode fibres. © 2012 IOP Publishing Ltd and Sissa Medialab srl.
