“…Specifically, effective bitrates of 94Gb/s over 2m of OM4 multimode fiber (MMF) with an 850nm VCSEL, 95.8Gb/s with a 1550nm VCSEL, and 71Gb/s over 7m of OM3 MMF with an 850nm VCSEL were achieved by means of, respectively, four-level pulse amplitude modulation, 4 discrete multitone (DMT) modulation, 5 and non-return-to-zero direct modulation. 6 By exploiting the versatility of a multiband approach (i.e., carrierless amplitude phase modulation, CAP), 7 we have successfully transmitted an effective bitrate of over 100Gb/s through 100m of OM4 MMF. 8 Multiband CAP modulation provides the Continued on next page 7 For more detail, see Table 1.…”
