Optical Fibers Double Capacity Of Each Fiber

May 1, 2001
Said to more than double the capacity of transoceanic communications systems, the UltraWave family of next-generation optical fibers has what's claimed as the flattest dispersion slope of any submarine fiber to permit more channel capacity per fiber.

Said to more than double the capacity of transoceanic communications systems, the UltraWave family of next-generation optical fibers has what's claimed as the flattest dispersion slope of any submarine fiber to permit more channel capacity per fiber. UltraWave IDF is a new dispersion compensation fiber than has a dispersion slope that mirrors the slope of UltraWave SLA, a fiber with an effective area that is much larger than a standard single mode fiber. The inverse dispersion slope cancels the detrimental effect of dispersion slope across a wide spectrum of wavelengths, enabling a dramatic increase in the number of Dense Wave Division Multiplexing (DWDM) channels used in ultra long-haul transmission. The initial application of UltraWave SLA and IDF will be in ultra long-haul transoceanic networks where the system impacts are the greatest.
