Pre-coded NRZ and electrical duo-binary transmission in C and O-band at data bit rates up to 25 Gbit/s

In this paper we present real-time transmission performances up to 25 Gbit/s for optical access network. Our solution is based at transceiver side on pre-coded NRZ and electrical duo-binary modulations using limited electrical bandwidth DML in C and O band. At the receiver side, an electrical duo-binary receiver based on an 8 GHz APD photodiode combined with an online duo-binary to binary converter is employed.
