The 5G bearer network is generally divided into the metro access layer, the metro convergence layer, and the metro core layer/provincial trunk line to implement the forward and middle transmission functions of 5G services. Devices at each layer mainly rely on optical modules to connect. The typical application scenarios and requirements are analyzed as follows: […]

The NVIDIA DGX H100 is equipped with eight single-port ConnectX-7 network cards supporting NDR 400Gb/s bandwidth and two dual-port Bluefield-3 DPUs (200Gb/s) supporting IB/ Ethernet networks. The appearance is shown in the following figure. The DGX H100 is equipped with four QSFP56 ports for storage networks and In-Band management networks. In addition, there is one

DWDM (Dense wavelength division multiplexing) technology through the simultaneous transmission of multiple optical signals of different wavelengths on the optical fiber, to achieve multi-wavelength multiplexing, improve the transmission capacity of the optical fiber, is designed for large capacity, long distance transmission of the optical module. With the development and construction of 5G communication, DWDM is
