“…Optical fibers were chosen for the analog signal transmission between the PMT camera and the counting house because they are lightweight, compact, immune to electro-magnetic pick-up noise and provide no pulse dispersion and attenuation [9]. The signal attenuation at 1 km fiber length is about 2.3 dB for the chosen 850 nm wavelength of the VCSELs.…”

“…The response of the PMTs to sub-ns input light shows a pulse of FWHM of 1.0 -1.2 ns and rise and fall times of 600 and 700 ps correspondingly [8]. By modulating vertical cavity surface emitting laser (VCSEL) diodes in amplitude the ultra-fast analogue signals from the PMTs are transferred via 162m long, multimode graded index 50/125 µm diameter optical fibers to the counting house [9]. After transforming the light back to an electrical signal, the original PMT pulse has a FWHM of about 2.2 ns and rise and fall times of about 1ns.…”
