Design parameters for fluoride multimode fibers

Numerical calculations of losses due to polymer coatings and macrobending have been made for step-index multimode fluoride fibers. To minimize such losses, fiber parameters must be chosen to give a large value for V, the normalized frequency. Due to the long propagation wavelength (2.5 mu m) for fluoride fiber, the parameters needed are very different from those of silica fiber. Using the criterion that >or=90% of the modes have losses >
