100-112.Gbit/s complete ETDM systems based on monolithically integrated transmitter and receiver modules

Traditional intensity modulated two-level electrical time-division multiplexing (ETDM) transmission systems working at 100-112.Gbit/s were investigated. The complete ETDM systems based on monolithically integrated transmitter and receiver modules were demonstrated with bit-error-rate (BER) performance of 10^-8 at 107.Gbit/s, and near error-free standard forward error correction (FEC) threshold (2×10^-3) at 112.Gbit/s. The experiment results showed that directly modulated high-speed ETDM transmission systems with the symbol rates at 100.Gbaud and beyond were promising candidate for cost-effective 100.GbE applications and might be a preform of the next generation of Terabit/s Ethernet.
