“…The body of Fig. 1 shows the dependence of bandwidth on the launch angle for two different 850-nm source-to-fiber offsets based on data from a theoretical study of MMF dispersion [4]. For example, if there is a tilt of 2 -3.5 or an offset of 3 m, the bandwidth would be less than the OFL bandwidth, which is 366 MHz km in this case.…”

Abstract-The far field divergence angle distribution of verticalcavity surface-emitting lasers is found to exhibit dependence on the data pattern driving the lasers. Two 50% duty cycle 1.25-Gb/s data patterns chosen to cause the same thermal conditions but with frequency content differing by a factor of 16 resulted in changes in the beam profile distributions with up to a 30% power variation in the central on-axis portion of the beam. Examination of the temporal waveforms as a function of far field angle revealed overshoot in the on-axis power and undershoot in the off-axis portion of the beam.Index Terms-Beam divergence, data pattern dependent, far field, laser diode, multimode fiber optic.

Abstract-In this paper we present the architecture and experimental evaluation of a single-chip CMOS maximum-likelihood sequence detection (MLSD) transceiver for electronic dispersion compensation (EDC) of multimode optical fibers (MMF) at 10Gb/s data rate. The primary application of this transceiver is the 10GBASE-LRM standard for 10Gb/s Ethernet over MMF [1]. Application to single-mode fiber (SMF) channels and/or other standards is also possible. Both optical module and line card applications are discussed. The architecture of the receiver is discussed in considerable depth, including implementation details. Extensive experimental results on several channels are presented. For the precursor, postcursor, and symmetric stressors specified by the 10GBASE-LRM standard we demonstrate receiver sensitivities of -14.84dBm, -14.37dBm, and -13.68dBm, respectively, in a line card application with 6 inches of electrical interconnect. These sensitivities exceed the requirements of the standard by 8.34dBo, 7.87dBo, and 7.68dBo 1 , respectively. Measured results on industry defined worst-case fibers and on nonstationary channels such as the dynamic stressor defined by the 10GBASE-LRM standard are also presented.
