DESCRIPTION
This singlemode fiber has a pure silica core unlike telecommunication types which use doped silica. Pure silica resists radiation damage much better than doped silica and so this fiber is usable in an environment where radiation is present. It is suitable for 1300nm and 1550nm wavelengths.
Metal coated pure silica core fibers, have an additional advantage in some cases. It has been found that the damage that occurs with neutron radiation can be reduced by x100 using metal coated fibres and heating them to 400°C.
