Fiberguide Industries has introduced its metal jacket series of gold and aluminium coated optical fibres. These fibres have proven effective in a number of applications, including avionics/ aerospace; Raman spectroscopy and distributed temperature sensing (DTS) for down-hole oil and gas operations.
Originally developed for ultra-high reliability telecommunications, the metal coating preserves the fibre’s mechanical strength and provides resistance against static fatigue caused by long term tensile loading. Gold and aluminium coated fibres can also withstand a wide range of temperatures, with aluminium coated fibres rated from -269°C to +400°C and gold rated from -269°C to 700°C.
Gold or aluminium coating can be applied on continuous lengths to a wide variety of multimode, step index, graded index and single mode fibres. Core to clad ratios of 1.1, 1.2 and 1.4 are available with numerical apertures of 0.12 and 0.26. Non-standard sizes can also be manufactured by request.
Fiberguide’s products are available from AMS Technologies throughout Europe from local offices in France, Germany, Italy, Spain and the United Kingdom
