Research on Hybrid Amplification Technology of All-optical Data Center Interconnection

The accurate evaluation of the communication quality of the interconnection link of the data center is an important basis to realize the coordination in the data network. In this paper, a hybrid amplification model for all-optical data center interconnection networks based on wavelength selective switches is established, which can quickly evaluate indicators such as optical signal-to-noise ratio and bit error rate in the interconnected links. In this paper, the data center interconnection link under the condition of no repeater amplification is discussed. The amplifier selection schemes under different interconnection distances are given. Through the simulation, the influence of different path selection on the communication quality of the interconnection link is compared under the conditions of the same interconnection distance and optical power gain. According to the corresponding theoretical model and algorithm, the optimal routing of the data center Internet can be established.
