“…The technique consisted of depositing by chemical synthesis in vapour phase a thin layer of very pure, doped silica material inside a fused silica tube, which formed the basis for the modem low loss fibre production technology. Since the first important result of Coming, a continuous progress in loss decrease was obtained, very close to the theoretical minimum loss of 0.157 &/km [4] at b1.55 pm.…”

Abstract. At the beginning of the seventies, a break-through took place in the telecommunication research. The introduction of Chemical Vapour Deposition technology in the manufacture of optical fibres allowed both technical quality and economical convenience to realise optical networks, thus beginning the telecommunication revolution. Since that moment, a great development of the CVD techniques has been performed, introducing several methods to produce fibres with geometry and optical properties optimised for different applications. An overview of the different methods is given, and the problems which have been to be solved in these years are described.

Although this sensational phenomenon must have attracted some interest since its discovery, the number of related papers increased only after the turn of the century as a result of the rapid development of high power light sources (see Fig.…”

“…Since the inner detector will be kept cold and radiation induced attenuation (RIA) is known to be enhanced at low temperatures [5], cold tests also needed to be performed. Therefore, the RIA of several fibres at -25 • C was measured up to a dose of 500 kGy(Si) [7].…”

“…However, these tests were performed at a dose rate of 27 kGy(Si)/hr, orders of magnitude higher than that expected at the HL-LHC. Research has shown that RIA is strongly dependent upon dose rate [5,6], and so the other fibres could not be excluded from use. This paper describes tests performed at low temperatures (between -24 • C and -30 • C) and at a comparatively low dose rate of 0.7 kGy(Si)/hr.…”

ABSTRACT: The LHC luminosity upgrade, known as the HL-LHC, will require high-speed optical links to read out data from the detectors. Such links must be capable of withstanding high doses whilst being kept at low temperatures. Two single-mode and two multi-mode fibres were exposed to 200 kGy(Si) at a dose rate of about 700 Gy(Si)/hr, whilst being kept at about -25 • C. The radiation induced attenuation of these fibres was measured as the fibres accumulated dose. A conservative estimate has been made of the total attenuation expected for a realistic fibre route through the ATLAS detector after a lifetime dose at the HL-LHC. With safety factors, the maximum dose extrapolated to was 375 kGy(Si). All four fibres performed extremely well and were qualified for use at HL-LHC detectors.
