An exemplary composite optical fiber transmission line (200) and method are provided that result in significant advantages. The composite optical fiber transmission line (200) includes a standard single-mode fiber (202), such as an SMF-28 fiber, a dispersion shifted fiber (204), such as an NZDSF fiber, and a dispersion compensating fiber (206). The single-mode fiber (202) receives an input optical signal at a first end and generates a single-mode optical signal at a second end. The dispersion shifted fiber (204) receives the single-mode optical signal at a first end and generates an output optical signal at a second end. The dispersion compensating fiber (206) receives the output optical signal and generates a chromatic dispersion compensated signal that, preferably, is at some desired chromatic dispersion level. In one example, the residual chromatic dispersion of the composite optical fiber transmission line is zero or near zero, and the residual chromatic dispersion slope of the composite optical fiber transmission line (200) is zero or near zero.
