Researchers from IDLab (an imec research group at Ghent University and the University of Antwerp, Belgium) and Nokia Bell Labs have presented the first upstream linear burst-mode transimpedance amplifier (TIA) chip that accommodates 50 Gbit/s NRZ and 100 Gbit/s PAM-4 modulation. The chip enables optical line terminals (OLTs) to cope with upstream packets’ varying signal …
