ABSTRACT:
Multimode optical fiber local area networks, both intrabuilding and interbuilding, are optimized to take advantage of the wide wavelength operating range offered by co-pending patent application Ser. No. 10/408,076 “Enhanced Multimode Fiber” —a fiber provided both with: longitudinally spaced perturbations for inducing mode coupling and thereby lessening mode dispersion; and with a radial discontinuity for discouraging conversion of bound-to-cladding-modes and thereby lessening added loss previously associated with induced mode coupling.
