Abstract : An optical-fiber technique is investigated that allows data transmission through 200 km of dual-mode optical fibers wound onto a fibers can be used over longer distances than conventional single-mode fibers and can meet the goal for 200-km transmission. The design of the dual-mode fibers is discussed, and test data are presented on their bending loss. Results from modal-noise and modal-dispersion tests are also given, showing that modal- noise and modal-dispersion effects are negligible, if the second-order mode is loosely bound.
