Abstract
A symmetric, dispersion-managed fiber optic cable in accordance with the present invention includes a first and a second optical fiber. The first optical fiber is a conventional single mode fiber (SMF) type fiber and has a first effective area and a positive dispersion characteristic at a predetermined operating wavelength range. The first optical fiber is split into two segments each having substantially the same length. The second optical fiber has a second effective area and a negative dispersion characteristic at the operating wavelength range. Typically, second optical fiber is a DSF or an NZD fiber, both with negative dispersion and a small effective area. The second optical fiber is coupled between the two segments of the first fiber to create a fiber optic cable with an average total dispersion at the operating wavelength range which is substantially zero. The fiber optic cable may be incorporated into an optical fiber transmission system with an optical terminal and at least one repeater.
