TheFiber Doctorfeature is specifically designed to monitor the status of optical fibers and quickly locate fault points in the network. It uses advanced diagnostics and AI-driven analytics to:

Detect issues such as fiber breaks, attenuation, and connector faults.

Provide precise fault location information, reducing troubleshooting time and field visits.

Ensure high reliability and availability of the optical network.

Other options like 'Service Doctor' and 'Optical Doctor' focus on higher-layer services or optical performance but do not specialize in fiber-level diagnostics.

Huawei Optical Network Monitoring Best Practices

In asafe city scenario, outdoor monitoring is a critical requirement. Huawei recommends usingoutdoor monitoring ONTslike theEG8084PandPowerCube500for such deployments. These devices are ruggedized and designed to operate in harsh environmental conditions, making them ideal for outdoor surveillance applications.

While indoor monitoring ONTs and pre-connection ODN are useful in other scenarios, they are not specifically optimized for outdoor safe city deployments. Similarly, small and medium OLTs like the EA5801 and EA5800-X2 are suitable for smaller-scale networks but are not directly related to the safe city use case.

Campus OptiX (POL) Deployment Scenarios

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.

POL (Passive Optical LAN)refers to the application of Passive Optical Network (PON) technology in enterprise campus environments. It is a modern networking solution that replaces traditional copper-based Ethernet networks with fiber optics, offering higher bandwidth, longer reach, and lower maintenance costs. POL is widely used in scenarios such as education, healthcare, hospitality, and smart cities.

The other options---Procurement on Line, Port of Loading, and Point of Load---are unrelated to optical networking and refer to entirely different concepts.

Huawei offers a diverse range of Optical Line Terminal (OLT) models to cater to various network requirements. As of the latest product portfolio, Huawei's OLT family includesfive primary models:

MA5800 Series:High-density OLT for large-scale deployments (e.g., MA5800-X17,MA5800-X7).

EA5800 Series:Compact OLT for small and medium-sized networks (e.g., EA5800-X2).

OptiXstar Series:Specialized OLT for enterprise and campus networks.

SmartAX Series:Integrated OLT for multi-service access.

OSN Series:Advanced OLT for converged transport and access networks.

Each model is designed to address specific use cases, from large-scale service provider networks to small enterprise deployments.

Campus OptiX (POL) delivers significant value to customers through the following key benefits:

Simple Architecture:POL simplifies network design by using a single fiber infrastructure to deliver multiple services (voice, data, video), reducing complexity and cost.

Smart O&M:With centralized management tools like eSight, POL enables efficient monitoring, troubleshooting, and automation of network operations.

Easy to Evolve:POL supports future-proof technologies like XG-PON and NG-PON2, allowing seamless upgrades to higher bandwidths.

High Reliability:The passive nature of POL (no active components in the ODN) ensures high reliability and low maintenance requirements.

These advantages make POL an attractive solution for enterprise campuses and other large-scale deployments.

POL Deployment Best Practices

TheCampus OptiX (POL)solution is primarily deployed in scenarios where fiber-to-the-premises (FTTP) is required for high-speed connectivity. The main sale scenarios include:

Room-like Scenarios:POL is widely used in education (classrooms, dormitories), hotels (guest rooms), hospitals (patient rooms), and apartments, where individual units require dedicated connectivity.

Video Backhaul Scenarios:POL supports video surveillance and backhaul applications in safe city projects, parks, and industrial zones, ensuring reliable and high-quality video transmission.

While POL can technically support office and Wi-Fi backhaul scenarios, these are not its primary focus. Instead, these scenarios are better addressed by other Huawei solutions like Wi-Fi 6 or enterprise switches.

POL Deployment Scenarios

eSightis Huawei's flagship Network Management System (NMS) and plays a critical role in theCampus OptiX solution. It provides centralized management, monitoring, and operation of the entire POL network, including OLTs, ONTs, and the ODN infrastructure. Key features of eSight include:

Real-time monitoring of network performance and faults.

Automated service provisioning and configuration.

Comprehensive reporting and analytics for network optimization.

Without eSight, managing a large-scale POL deployment would be significantly more challenging, making it an essential component of the solution.

Type B Protectionin GPON networks refers to link-layer redundancy, where two independent fiber paths are used to connect an ONU to the OLT. In the event of a fiber failure, the system automatically switches to the backup path.

Theminimum protection switching timefor Type B protection is50 ms, ensuring minimal disruption to services. This rapid switching time is critical for maintaining high availability and reliability in mission-critical applications.
