Abstract

The Telecommunications Industry Association (TIA) FO-2.2.1 Working Group on the Modal Dependence of Bandwidth has conducted industry wide inter-laboratory comparisons on measurements aimed at improving the bandwidth performance of short-wavelength, laser-based, multimode-fiber local area networks (LANs). Measurements of both transceiver 'encircled flux' and fiber 'restricted-mode-launch bandwidth' can together successfully predict an enhanced system performance provided the proper limiting criteria are selected. System performance is determined by a measurement of 'effective bandwidth' and/or inter-symbol interference. Recommendations for source and fiber selection criteria come from a risk analysis of an extensive multi-laboratory comparison involving 95 fibers and 69 laser transceivers. For this paper, 'enhanced system performance' is defined as a performance that allows operation at a data rate of at least one gigabit-per-second data rate operation over a 500 meter length of 62.5/125 υm graded-index glass fiber.
