ASI Anhydrous Silica SM Fibers

Product information "ASI Anhydrous Silica SM Fibers"

Single Mode; 633 to 680, 1310 nm; Mode Field Diameter 4.3, 9.0 µm; Cladding Diameter 125 µm; Coating Acrylate, Polyimide, Aluminium, Gold; Numerical Aperture 0.12

Fiberguide’s ASI series of silica core, silica clad, polymer or metal coated single mode fibers is used in data transmission applications as well as photonics applications where a single optical path, or mode, is desired.

The ASI fiber series is available with acrylate (-Y) coatings and also high performance Polyimide (-T), aluminium (-A), and gold (-G) coatings that allow these fibers to exceed the temperature performance levels of standard fibers.

Additionally, the ASI series fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
