Fiber networks consist of both old and new fibers, all of which must be used to maximum efficiency. Initially, fiber-optic networks operated at a wavelength of 1310 nm and many of the fibers installed at this time were never characterized in the 1550 nm window. One additional problem that should not be overlooked is that shifted and unshifted fibers may have been accidentally combined, along with compensation modules and amplifiers, which can generate unusual dispersion characteristics.
