An optical coherence tomography (OCT) interferometer includes at least a first optical fiber of a first type having a first length, in series with a second optical fiber of a second type which is different than the first type and having a second length, in at least one of the sample path and/or the reference path of the OCT interferometer. The dispersion characteristics of the first optical fiber and the second optical fiber are significantly different than each other. As a result, the total group delay dispersion of a first portion of the laser light passing through the sample path and the total group delay dispersion of the second portion of the laser light passing through the reference path may offset each other at the detector.
