Single Mode Fibers available from Stock
Our range of single mode (SM) optical fibers available from stock is used for a multitude of challenging applications. They allow transmission of optical signals over very long distances and are offered with special features like high operating temperatures, high index of refraction or low bend sensitivity.
Product Portfolio
As an option, some of our single mode fibers are also available in a metalized version. With these high-performance aluminium or gold coatings, the fibers work reliably even at extreme temperatures and withstand harsh environmental conditions.
AMS Technologies’ portfolio also includes specialized single mode fibers made from anhydrous silica, single mode fiber tapers, tapered and lensed SM fibers, as well as SM fibers with reduced cladding diameter, hermetic coating or optimized for visible wavelengths.
Some of the fibers can be equipped with anti-reflection technologies, enhancing transmission performance and increasing damage thresholds. In addition to common anti-reflection coatings, a technology based on nano-structures on the surface is available for selected fibers.

Beyond single mode fibers, our large portfolio of optical and specialty fibers for a wide wavelength range includes multi mode (MM) fibers and polarization maintaining (PM) fibers as well as doped fibers or plastic optical fibers (POF).
Complementing our optical fiber offerings, AMS Technologies carries a large portfolio of fiber connectors, accompanied by a range of corresponding female mating sleeves and adapters. AMS Technologies can also offer an end-to-end solution for the assembly and test of fiber connectors that is exactly tailored to your requirements. In our broad portfolio you can find tools for stripping and cleaving your fibers, gluing and curing the fiber into the fiber connector using optical adhesives, polishing and cleaning of fiber optic end faces (especially important if the fiber is used with higher optical power), and finally testing your fiber connector with microscopes, interferometers as well as handheld and automated test equipment measuring return loss.
If you prefer pre-manufactured, ready to use fibers with the connectors already assembled to them, take a look at our range of SM, MM or PM patch cables. Shaped fiber tips or endcaps are further available options, improving the performance of the fiber-to-air interface, especially for high optical powers.

Definition
Optical or glass fibers can be used for many different applications, with the main purpose to transport light over a certain distance. Optical fibers consist mainly of a core with a certain diameter, a cladding and a coating.
Single mode (SM) optical fibers feature a small diameter of the fiber core (in the range of 2.5 µm to 10 µm), supporting mode field diameters from 2µm (320nm) up to 9µm (1550nm) and allowing propagation of light in just one (transversal or fundamental) optical mode which will not undergo dispersion effects causing signal distortion over long distances. Thus, the fiber shows a significantly higher pulse shape fidelity compared to using a multi mode fiber – significantly extending the bandwidth of an optical transmission.
The most common cladding diameter of single mode fibers is 125 µm, but other diameters are available as well.
Single mode fibers are used for a wide range of challenging applications. They allow transmission of optical signals over very long distances and are also available with special features like high operating temperatures, high refractive index, reduced cladding diameters, low bend sensitivity or a broad variety of coatings.
To protect the fibers against higher temperatures, they can be coated with different materials like acrylate (for medium temperature levels), aluminium or gold, making the fibers usable in harsh environments. If further protection is needed, an additional flexible metal tube will make them even more durable, especially for industrial applications.
The performance of a single mode fiber can be enhanced by antireflecting coatings at the fiber’s end face. A special plasma-based nano-structuring technology can raise the damage threshold of the fiber for selected fibers. Shaped fiber tips or endcaps are further options to improve the performance of the fiber-to-air interface.
