Alcatel-Lucent, which used the oscilloscope to demonstrate a coherent optical receiver capable of detecting a 160-Gbaud QPSK, said the 100-GHz bandwidth and 240-GSa/s sampling rate of the LabMaster were "key" in building the system and noted that, in general, an oscilloscope's bandwidth will no longer be a limiting factor. Rather, with the LabMaster, the oscilloscope bandwidth exceeds that of the transmitter and optical-to-electrical converter.
