Description
The read-out of the ATLAS TRT requires about 30000 digital links working at 40 Mbits/s. For cost reasons it
was not possible to use fibre optics technology in the tracker volume of ATLAS. LVDS links using very thin
twisted pair lins (36 AWG) have been implemented up to a point where a small number of optical Gbits links
are used.
Complex harnesses, including the small twisted pairs, the low and high voltage cables have been designed
and are currently being fabricated.
The paper will focus on the difficulties encountered to run high speed links on very thin cables and show how
they were specified and validated. Then the production process and its status will be presented.
