T4DH is a high-density single-slot 200G TMUX card from the STN6800-D16 platform of Sino-Telecom. It is a 2*100G tributary line aggregation card, suitable for STN6800-D16-1U/2U network elements.
The T4DH card is a dual-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 4*100G service access and is equipped with 100G and OTU4 functions;
The line test supports coherent 2*200G CFP DCO color light modules.
