A 400-Gb/s and Low-Power Physical-Layer Architecture for Next-Generation Ethernet
A new 400-Gb/s (100-Gb/s?4) physical-layer architecture for the next-generation Ethernet - using 100-Gb/s serial (optical single wavelength) transmission - is proposed. For the next-generation 400-Gb/s Ethernet, there are additional requirements from the market, such as power reduction and further compactization in addition to attaining even higher transmission speed. To meet these requirements, a 100-Gb/s?4 physical-layer architecture is proposed. This architecture uses a 100-Gb/s serial (optical single wavelength) transmission Ethernet and low-power control technologies, which include transmission capacity-degeneracy control for multi-lane transmission Ethernet.
