Fiber Amplifiers-Erbium Doped
Carbon-coated for high static fatigue and submarine applications
Far beneath the sea, amplifiers are subjected to water and, with the passage of time, and the gradual corrosion of metallic components, hydrogen. Twenty-year lifetimes are in doubt when the integrity of a key component is threatened by microcracks and increased attenuation.
DF1500FS is hermetically sealed with a layer of amorphous carbon 20-40 nm thick. In tests, this carbon layer has demonstrated an ability to slow-down hydrogen ingression by almost three orders of magnitude, even when subjected to a pressure of 100 atmospheres. A typical Stress-Corrosion Factor 'N' of 100 can also be shown to increase dramatically the lifetime of even the most tightly packaged gain-sections.
Typical Performance at 1550 nm
1. Background loss is measured at 1200 nm because of
the influence of both the short wavelength edge of the 1531nm absorption peak
and other structures encountered at 1300nm.
