60 Gbaud NRZ Transmission with 0.94 pJ/b Direct-Drive Optical Transmitter Using SM 1060 nm VCSEL Over 5 km SMF

Abstract

We present a direct-drive optical transmitter demonstrating 60 GBd NRZ transmission with single-mode (SM) 1060 nm VCSEL over 5 km single-mode fiber (SMF), achieving a bit-error-rate (BER) < 1 e-12 after forward-error-correction (FEC) with a record-high FEC-corrected bitrate-distance product of 283.47 Gb/s.km and 0.94 pJ/b transmitter energy-efficiency.
