Standard singlemode fibers
SM Series

Single mode fibers are readily available for telecom wavelengths (1300 nm and 1550 nm) with acrylate coating. Oxford Electronics fibers are available in additional wavelengths, a choice of cladding diameters and are also available with higher temperature polyimide coatings.

These fibers can be supplied as cables or patchcords with Kevlar reinforced jackets and fitted with a variety of connectors. See patchcords for jacket information.

Acrylate coated fibers are suitable for temperatures from -40ºC to +85ºC. Polyimide coated fibers are suitable for temperatures from -190º to +350ºC.

Acrylate

Coating diameter (125 µm fibers) = 280 µm
Coating diameter (80 µm fibers) = 190 µm

Polyimide

Coating diameter (125 µm fibers) = 140 µm

Other wavelengths can be supplied to order.



Singlemode fibers are also available with CuBALL high temperature metal coatings.
