T4QEH is a high-density single-slot 800G TMUX card for the STN6800-D16 platform from Sino-Telecom. It is a 4*400G tributary aggregation card suitable for the STN6800-D16-2U network element.
The T4QEH board card integrates two independent wavelength converters, each of which can operate in 800G mode;
The client side supports 400G QSFP-DD112 type optical modules;
The line test supports coherent 800G OSFP DCO color light modules.
