the waveguide structure of Dispersion Compensation Fiber(DCF) is designed and a kind of high-performance DCF fabricated.The test results show that it has fairly large negative dispersion in the wavelength range of 1 525 nm-1 625 nm
e.g.-141 ps/nm/km at 1 545 nm.Wideband dispersion compensation modules(DCM) are manufactured with this DCF.When G.652 fiber transmission links are compensated by this DCM
the residual dispersion in C-band is smaller than 5.0 ps/nm and the dispersion slope of the C band are also compensated by 100%.
