T2QQH is a high-density single-slot 400G TMUX card for the STN6800-D16 platform from Sino-Telecom. It is a 2*400G tributary line aggregation card suitable for STN6800-D16-1U/2U network elements.
The T2QQH board card integrates two independent transponders, each of which can operate in 400G mode;
The client side supports 2×400G QSFP-DD type optical modules, including DR4, LR4, FR4, SR8, and LR8;
The line test supports coherent 2*400G CFP DCO color light modules.
