Gold and Aluminum Coated Fibers from Fiberguide Industries

Metal jacket series of optical fibers can withstand temperatures up to 700°C

Stirling, N.J. (May 25, 2010) – Delivering reliable operation in extreme conditions, Fiberguide Industries provides its metal jacket series of gold and aluminum coated optical fibers.  These fibers 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.

Fiberguide’s Gold and Aluminum coated fibers for performance in extreme conditions.

Fiberguide’s Gold and Aluminum coated fibers for performance in extreme conditions.

Originally developed for ultra high reliability telecommunications, the metal coating preserves the fiber’s mechanical strength and provides resistance against static fatigue caused by long term tensile loading.  Gold and aluminum coated fibers also can withstand a wide range of temperatures, with aluminum coated fibers rated from -269°C to +400°C and gold rated from -269°C to 700°C. 

Gold or aluminum coating can be applied on continuous lengths to a wide variety of multimode, step index, graded index and single mode fibers.  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.
