The correct answer is38.4T. TheOptiXtrans DC908supports a maximum single-fiber capacity of38.4 Tbps, making it one of the most advanced solutions for high-capacity optical transport.
Here's how the DC908 achieves this capacity:
* WDM Technology:Combines multiple wavelengths on a single fiber, each carrying data at speeds up to
400G.
* Advanced Modulation:Uses modulation schemes like DP-16QAM to maximize spectral efficiency, enabling higher data rates within the same fiber spectrum.
* High Density:Supports up to96 wavelengths per fiber, resulting in a total capacity of38.4 Tbps(96 x
400G).
* Future-Proofing:Designed to accommodate emerging technologies like 800G wavelengths, ensuring scalability for future demands.
This level of capacity is critical for applications like data center interconnects, where large volumes of data need to be transmitted over long distances without bottlenecks.

TheOptiXtrans DC908is specifically designed forData Center Interconnect (DCI)applications. Its key features align perfectly with the requirements of modern DCI scenarios:
* High Capacity:Supports up to 800G per wavelength, enabling ultra-high-speed connectivity between data centers.
* Compact Design:The 2U form factor makes it ideal for space-constrained environments.
* Low Latency:Optimized for minimal delays, critical for applications like cloud computing and disaster recovery.
* Simplified Deployment:Plug-and-play functionality reduces operational complexity.
While other Huawei products (e.g., OptiXtrans E9600) are designed for backbone or metro networks, the DC908 is tailored exclusively for DCI.

When deployingNCE-FAN Liteon aBare Metalinfrastructure, Huawei recommends using theTaiShan Server, which is part of its ARM-based server portfolio. In this scenario, the correct offering to select is Network Cloud Engine-FAN Lite HW.
The "HW" suffix indicates that the solution includes hardware components (e.g., the TaiShan Server) in addition to the software. This is ideal for customers who prefer an integrated hardware and software package rather than deploying the software on their own servers.
Other options like "Network Cloud Engine-FAN Lite" or "NCE_FusionCompute" are software-only solutions and do not include the TaiShan Server.
