M20DH is a high-density dual-slot 200G TMUX card for the STN6800-D16 platform from Sino-Telecom. It is a 2*10G tributary line aggregation card suitable for STN6800-D16-1U/2U network elements.
The M20DH card is a single-channel multiplexer designed for high-capacity optical transmission networks;
Its modular and scalable architecture supports on-demand expansion, offering the flexible "pay-as-you-go" advantage;
The client side supports 20*10G service access and is equipped with functions such as 10G WAN/LAN, OTU2, OTU2E, STM-64, FC3200, FC1600, FC800, and GE;
The line test supports coherent 1*200G CFP DCO color light module.
