56 Gbaud EMLs and drivers from NeoPhotonics provide interfaces for 400 Gbit/s transceivers

56 Gbaud externally modulated lasers (EMLs) and drivers provide interfaces for 400 Gbit/s transceivers. With a PAM4 modulation scheme, an EML and a 56 Gbaud linear driver can achieve 100 Gbit/s with a single laser. Alternatively, a traditional NRZ modulation scheme with the EML and limiting driver can deliver 400 Gbit/s capacity with eight wavelengths.
