Fiberguide’s Graded Index Fibers Ideal for Telecommunications

Only graded index fibers available with gold, polyimide and aluminum coatings

Stirling, N.J. (January 21, 2011) –  For reliable use in data communication links, Fiberguide Industries provides its AGI™ Series of Graded Index Silica core/ Silica clad optical fibers.

Fiberguide Industries’ AGI™ Series of graded index optical fibers.

Fiberguide Industries’ AGI™ Series of graded index optical fibers.

The AGI Series offers the high bandwidth of single mode fibers with the convenient termination of step-index multimode fibers.  The result is a fiber with good bandwidth that can be used with lower cost light emitting diodes, making it a popular choice for medium distance data communication links such as local area networks (LANs).

Fiberguide Industries is the only supplier of graded index silica fibers to offer premium coatings for reliable performance in extreme temperature conditions such as polyimide (-190ºC to +350 ºC), aluminum (-269ºC to +400 ºC) and gold (-269ºC to +700ºC).  Fibers are also available in a variety of sizes to fit customer applications.  The AGI Series 50/125 is available with core diameters from 50µm ± 3µm and clad diameters from 125µm ± 1µm/-3µm.  The AGI Series 62.5/125 has core diameters from 62.5µm ± 3µm and clad diameters from 125µm + 1µm/-3µm.

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.

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.
