3.2T DWDM System

The HT6800 3.2T DWDM System is an ultra-high-integration DCI transmission platform built for small-to-large metro and data center interconnection. Standard 1U chassis supports 3.2T (4×800G service slots); 2U chassis scales to 6.4T (8×800G service slots), reaching industry-leading density. It features flexible rate services, white-box open architecture, and full data center environment adaptability with hot-pluggable modules and forward/rear air cooling design.
