Low Complexity up to 400-Gb/s Transmission in the 1310-nm Wavelength Domain

In this letter, we demonstrate low complexity dense wavelength-division multiplexing (DWDM) over a ~ 40-km standard single-mode fiber transmission system in the 1310-nm wavelength domain with a total transmission capacity up to 400 Gb/s. The demonstrated system is based exclusively on semiconductor components without any form of dispersion compensation. The system showed excellent performance. The presented results prove that the 1310-nm wavelength domain can support low cost and low complexity high-speed transmission with the wide range applications like the future 400G+ Ethernet.
