Y. Kuriyama et al., OVER 40 GBIT S ULTRAHIGH-SPEED MULTIPLEXER IC IMPLEMENTED WITH HIGH FMAXALGAAS/GAAS HBTS/, Electronics Letters, 30(5), 1994, pp. 401-402
An ultrahigh-speed multiplexer (MUX) circuit has been developed for fu
ture optical transmission systems. The IC was fabricated with 160 Hz f
(max) AlGaAs/GaAs HBTs. Error-free 40Gbit/s operation with an 0.8V pea
k-to-peak output voltage swing was confirmed. Its 50Gbit/s operation w
ith an output voltage swing of 0.3V peak-to-peak was also verified. Th
ese are, to the authors' knowledge, the fastest operation speeds ever
reported for a MUX IC implemented with any type of device.
