Definitions
- Figure 8 shows a refractive index profile corresponding to another preferred embodiment of an optical waveguide fiber as disclosed herein;
- Figure 9 shows a refractive index profile corresponding to another preferred embodiment of an optical waveguide fiber as disclosed herein;
- a low water peak also affords improved pump efficiency of a pump light emitting device which is optically coupled to the optical fiber, such as a Raman pump or Raman amplifier which may operate at one or more pump wavelengths.
- a Raman amplifier pumps at one or more wavelengths which are about 100 nm lower than any desired operating wavelength or wavelength region.
- an optical fiber carrying an operating signal at wavelength of around 1550 nm may be pumped with a Raman amplifier at a pump wavelength of around 1450 nm.
- the lower fiber attenuation in the wavelength region from about 1400 nm to about 1500 nmn would tend to decrease the pump attenuation and increase the pump efficiency, e.g.
