| Abstract: | This paper describes a novel method designed to measure the chromatic dispersion of installed single-mode fiber cables. The systems developed utilize the modulation phase/multiple laser diode techniques; however, by the addition of wavelength division multiplexing, the reference laser and fiber was eliminated. Laboratory and field results for measured wavelength ranges of 1200-1330 and 1200-1550 nm are presented. |
