Thus, B and C are the verified advantages.

The Huawei OptiXtrans DC908 is a Data Center Interconnect (DCI) solution tailored for high-performance, low-latency, and simplified deployment in data center scenarios. While Huawei’s optical solutions, including the DC908, are widely deployed globally, the specific claim of "620,000+ optical devices commercially used worldwide" is not explicitly documented as a key feature of the DC908 in official HCSA-Sales-Transmission & Access materials. The DC908’s key features focus on aspects like high capacity (e.g., 88T per fiber), low power consumption (35% lower than the industry average), rapid commissioning (within 8 minutes), and cost-effective payback (within 1 year for self-built networks). The figure of 620,000+ devices might pertain to Huawei’s broader optical portfolio, but it is not a verified key feature specific to the DC908. Thus, the statement is FALSE in this context.

Huawei’s Network-Level WebGUI offers key features that improve network management efficiency:
