Energy efficient 850nm VCSEL-based optical transmitter and receiver link capable of 80Gbps NRZ Multi-Mode fiber data transmission

In this article, we report on energy efficient (6.2 mW/Gbit/s) transmitter and receiver assemblies capable of NRZ 80 Gbit/s and 72 Gbit/s fiber data transmission through 2 and 50 m of MMF, respectively. The optical link studied consisted of a 130 nm BiCMOS driver and transimpedance amplifier, ∼30 GHz VCSEL, and ∼27 GHz PD.
