70+Gb/s VCSEL-Based Multimode Fiber Links

View publication


We report on an 850nm VCSEL based link operating error free to 71 Gb/s using an NRZ modulation format. This optical link uses custom transmitter and receiver ICs with 2-tap Feed Forward Equalization implemented in 130nm BiCMOS and GaAs based VCSELs and photodiodes. This paper covers new aspects of the circuits and packaging.
