[摘要]：We investigate transmission of 112 Gb/s PM-QPSK signals over 50 mu m core diameter OM3 multimode fiber using the center launch approach. We demonstrate successful transmission of 16 DWDM channels over a distance of 635 km for a capacity-distance product of 1016 Tb/s-km. The limiting impairment appears due to mode coupling and multipath interference effects. (C)2011 Optical Society of America
