N. Ujiie et al., A TIME-EXTENDED OPTICAL READOUT TRANSMISSION SCHEME TO A HIGH-DENSITYDETECTOR SYSTEM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 342(1), 1994, pp. 186-192
Extended time division multiplexing (TDM) combined with wave division
multiplexing (WDM) is used to form a WTDM data-transmission system hav
ing optical devices. This system has a possible application with a det
ector having an enormous number of readout channels (greater-than-or-e
qual-to a few million), e.g. typical silicon (Si) micro(mu)strip detec
tors for the SSC or LHC as well as others used in future high-energy p
hysics experiments. The optical WTDM data-transfer scheme has a factor
of 1000 reduction in the number of cables and is therefore very fast,
yet it includes individual readout.
