Claim Text:
1. An assembly for guiding and protecting optical fibre cables or optical wave guides, comprising: a first plurality of first guide tubes and a second plurality of second guide tubes, each of said first and second guide tubes being adapted for receiving an optical fibre cable along its complete length, the first and second guide tubes exhibiting a longitudinal thermal expansion; an elongated first tubular shell and an elongated second tubular shell formed together with an interconnecting connecting strip, said first plurality of first guide tubes being enveloped with an interference fit within said first tubular shell, and said second plurality of second guide tubes being enveloped with an interference fit within said second tubular shell, said first and second tubular shells exhibiting a longitudinal thermal expansion; said connecting strip defining a separation between said first and second tubular shells and positioning said first plurality of first guide tubes and said second plurality of second guide tubes in parallel; and a third plurality of elongated strength elements in parallel relationship with said first and second guide tubes and embedded in said connecting strip, the elongated strength elements exhibiting a longitudinal thermal expansion smaller than the longitudinal thermal expansion of said first and second guide tubes.
