Abstract
Using a SiGe analog multiplexer (AMUX) integrated circuit we generate a PAM-8 signal at 176 GBd by time-interleaving two 88 GBd tributaries. High-quality signal is obtained after interleaving thanks to the excellent linearity of the AMUX. We successfully demonstrate net bitrates up to 467 Gbit/s after 2 km fiber transmission.
