Optimized Laser Launch Conditions in 10 Gb/s Links Using Next Generation Multimode Fibers

In this paper we present the dependence of the ISI penalty on various transmitter and fiber parameters characterizing 10 Gb/s Ethernet links at 850nm with 300m long next-generation multimode fiber. Statistical optimization of the launch conditions results in optimal values for the laser encircled flux (13-17mm) and lateral offset of the source (10-18mm). The analysis of the ISI correlation coefficients showed that the axial offset has detrimental effects on the performance of the link and it should be less than 60 mm.
