The correct answer isOLT + ODN + ONU + eSight. The Campus OptiX (POL) solution includes the following key components:

OLT (Optical Line Terminal):Centralized device at the service provider's end for managing and controlling the network.

ODN (Optical Distribution Network):Passive optical splitters and fiber cables that distribute signals to end users.

ONU (Optical Network Unit):End-user devices that connect to the ODN and provide services like data, voice, and video.

eSight:Huawei's network management system that provides centralized monitoring, configuration, and maintenance for the entire POL network.

WhileU2000is another Huawei network management tool, it is more commonly used for carrier-grade networks rather than enterprise-focused solutions like Campus OptiX.

Optical modules are categorized based on their transmission distance and power budget. The most commonly used classes in commercial deployments are:

Class B+:Supports distances up to 20 km and is widely used in urban and suburban areas.

Class C+:Supports distances up to 40 km and is suitable for medium-range deployments.

Class D:Supports distances up to 60 km and is ideal for long-haul connections in remote areas.

ClassesEandFare either outdated or not commercially viable due to their limited use cases.

The statement isTrue. Huawei has consistently been a leader in contributing to international standards organizations such as theITU (International Telecommunication Union). Huawei's significant contributions to ITU standards, particularly in areas like optical transmission, access networks, and 5G, have positioned it as a top contributor in terms of patents and technical proposals. This leadership reflects Huawei's commitment to innovation and its role in shaping global telecommunications standards.

TheCampus OptiX solutionis a comprehensive offering that integrates multiple components to deliver a complete Passive Optical LAN (POL) solution. The main sale products include:

OLT (Optical Line Terminal):Central device for managing the network.

ODN (Optical Distribution Network):Passive infrastructure for signal distribution.

ONU/ONT (Optical Network Unit/Terminal):Customer-side devices for connecting end-users.

eSight:Huawei's network management system (NMS) for centralized monitoring and management of the entire network.

While options like "OLT + ODN + ONU" or "OLT + ONT" represent subsets of the solution, the inclusion ofeSightis critical for effective network management and operation, making option A the most complete and accurate choice.

TheNCE-T (Network Cloud Engine - Transport)fully supportsvirtualization deployment. It can be deployed as a virtualized application on cloud platforms, leveraging technologies like VMware, OpenStack, or Kubernetes.

Key benefits of virtualization:

Scalability:Virtualized deployment allows NCE-T to scale dynamically based on network demands.

Flexibility:Enables integration with cloud-native environments and multi-vendor ecosystems.

Cost Efficiency:Reduces hardware dependency by running on shared infrastructure.

The statement that NCE-T does not support virtualization is therefore incorrect.

Huawei Cloud-Native Networking Best Practices

The evolution ofData Center Interconnect (DCI)networks has been driven by the increasing demand for high-speed, reliable, and scalable connectivity between data centers. Modern DCI networks are evolving toward the following characteristics:

Mesh Architecture:Enables multiple redundant paths between data centers, improving resilience and fault tolerance.

Simplified Deployment:Leveraging plug-and-play devices and automated provisioning reduces complexity and speeds up deployment.

Intelligent Management:AI-driven analytics and automation optimize network performance, predict faults, and streamline operations.

Huawei’sOptiXtrans DC908exemplifies these trends, offering high capacity, low latency, and intelligent O&M capabilities.

Thus, the statement is correct.
