Fiber stretcher module for use in the wavelength range of 1550 nm

摘要

Embodiments of the present invention is generally related to the fiber stretcher module for use in the wavelength range of 1550nm. In one embodiment of the present invention , the fiber stretcher module for use in the wavelength range of 1550nm to about 0.0002nm at about 1550nm ^-2 Large relative dispersion curvature than , and about -60ps / (nm km) and a first fiber with a smaller variance , at about 1550nm, the values of the relative dispersion curvature is approximately zero , and about 0.003nm ^-1 And a second fiber with a value of the relative dispersion slope is , the fiber stretcher module , at 1550nm, about 0.0413nm ^-1 Relative dispersion gradient bound of , and about 0.00286nm ^-2 I comprise of relative dispersion curvature .
