The correct answer is1. TheOptiXtrans DC908is designed to support high-density configurations, allowing an
8x200G (2x100GE)WDM system to be deployed using justone chassis.
Here's a breakdown of how this is achieved:
* High Integration:The DC908 integrates multiple components, such as optical modules, amplifiers, and control units, into a single compact2U chassis. This eliminates the need for additional hardware or external devices.
* Scalability:The DC908 supports up to8 wavelengths per fiber pair, each operating at200G. This means that all 8x200G channels can be accommodated within a single device.
* Service Aggregation:Each 200G wavelength can carry multiple 100GE services, enablingefficient aggregation of traffic. For example, two 100GE services can be mapped onto a single 200G wavelength.
* Space Efficiency:By consolidating everything into one chassis, the DC908 minimizes rack space requirements, making it ideal for data centers and edge locations where space is limited.
Other options:
* 2, 3, or 4 chassis:These would only be necessary for extremely large-scale deployments or if additional redundancy were required. However, for an 8x200G system, a single chassis is sufficient.
This compact design highlights the DC908's efficiency and cost-effectiveness for modern optical networks.

TheOptiXtrans DC908is a cutting-edge data center interconnect (DCI) solution with several key highlights:
* High Security:Provides end-to-end encryption and physical isolation to protect sensitive data.
* Intelligent O&M:Leverages AI-driven analytics and automation for efficient network management.
* Simplified Provisioning:Enables plug-and-play deployment and automated service provisioning, reducing operational complexity.
* Ultra Broadband & High Integration:Supports up to 800G per wavelength and integrates multiple functions into a compact 2U form factor, maximizing capacity and efficiency.
These features make the DC908 ideal for modern data center interconnect scenarios.

The statement isTrue. TheOptiXtrans DC908can be managed using aWebGUI (Web Graphical User Interface), providing a user-friendly way to configure, monitor, and troubleshoot the device.
Key features of the WebGUI include:
* Ease of Use:The WebGUI offers an intuitive interface for operators, reducing the learning curve compared to command-line tools.
* Centralized Management:Provides access to key functions like performance monitoring, fault detection, and service provisioning.
* Remote Access:Enables administrators to manage the DC908 from any location with internet connectivity, improving operational efficiency.
* Integration with NCE:While the WebGUI is available for standalone management, the DC908 also integrates seamlessly with Huawei'sNCE (Network Cloud Engine)for advanced automation and orchestration.
This flexibility in management options makes the DC908 suitable for both small-scale deployments and large- scale carrier networks.
