Paper Abstract

The evolving technology of high-order-mode dispersion management is discussed. Selected high-order modes of specially designed fibers can have high dispersion of a few hundreds psec/nm*km, controlled dispersion-slope in the range of 1.5 to 10 psec/nm2*km, and large effective area of 60 to 80mm2. Thus, the technology enables the construction of dispersion management devices with low-loss, accurate broadband dispersion compensation for a variety of transmission fibers, and low sensitivity to non-linear effects. Compared to standard fundamental-mode-based devices, the high-order-mode-based devices may have as much as 6 dB advantage in insertion loss and 6 to 13 dB advantage in power tolerance to non-linear effects. Specific high power tests show a 13 dB higher threshold to stimulated Brillouin scattering and 6 to 10 dB advantage in sensitivity to self-phase modulation. Line amplifiers designed and built around these high-order-mode devices may have an advantage of 1 dB or more in Noise Figure, thereby enabling significantly longer reach of optical links.
