Abstract
An offset launch scheme for multimode fibers (MMF) which provides substantial bandwidth enhancement while allowing large numbers of modes to be excited is presented. The technique is stable against environmental influences and is useful for gigabit/s MMF links from 1 to 2 km. Using this technique, bitrate-distance products of 7.5 and 2 GBit/s.km were achieved in standard 50/125 μm MMF at operating wavelengths of 1.3 and 0.85 μm, respectively. The products were up to four times those obtainable with a conventional launch. The technique excites approximately 60% of the fiber modes. In addition, it shows no susceptibility to environmental variations, a problem encountered in some low-order mode launch schemes.
