Trends in Data Center Interconnect Evolution

Deploying networks inremote areaspresents unique challenges, such as limited infrastructure, harsh environmental conditions, and high costs. To address these challenges, Huawei proposes the following solutions:

Outdoor Site Cabinet for OLT:Compact and ruggedized cabinets house the OLT and associated equipment, enabling deployment in outdoor environments without the need for dedicated indoor spaces.

Class D Optical Module:These modules are designed for long-distance transmission (up to 20 km), making them ideal for connecting remote areas to the central OLT.

WhileFlex-PONandCombo PONare innovative technologies, they are more focused on optimizing network capacity and efficiency rather than addressing the specific challenges of remote deployments.

All the options are correct. TheNCE-T (Network Cloud Engine for Transport)offers a comprehensive suite of features to enhance optical transport network management and service delivery. Here’s a breakdown of each highlight:

Visualized Bandwidth Resources:

Provides a graphical representation of bandwidth utilization across the network.

Enables operators to identify bottlenecks, optimize resource allocation, and plan capacity upgrades.

Optical VPN (OVPN):

Creates dedicated virtual paths (hard pipes) for specific services or customers, ensuring isolation and security.

Ideal for applications like financial trading, government communications, and enterprise connectivity.

Optical Service Provisioning:

Automates the provisioning of optical services, reducing manual intervention and speeding up service delivery.

Supports diverse services like OTN, Ethernet, and SDH.

CPE Plug and Play:

Simplifies the deployment of customer premises equipment (CPE) by automating configuration and activation.

Reduces installation time and operational costs, especially for large-scale rollouts.

Optical Latency Map:

Provides real-time visualization of latency across the network.

Helps operators optimize routing for low-latency applications like cloud computing, AI, and 5G backhaul.

These features collectively enhance the efficiency, reliability, and profitability of optical transport networks.

TheOSN 1800 Vis a compact device designed for outdoor and edge deployments. Unlike other models in the OSN 1800 series, itcannot be mounted in a standard 19-inch cabinetdue to its unique form factor and intended use case.

Here’s an analysis of the other options:

OSN 1800 I:Can be mounted in a 19-inch cabinet and is commonly used in small-scale deployments.

OSN 9800 U32:A high-end platform designed for core networks, typically deployed in data centers or telecom rooms with 19-inch racks.

OSN 1800 II:Supports 19-inch cabinet mounting and is used in metro and regional networks.

Thus, theOSN 1800 Vis the correct answer.

The statement isTrue. TheSmartWiFifeature in Huawei’s solutions supports theSaaS (Software as a Service)model, enabling service providers to offer managed Wi-Fi services to their customers.

Key aspects of SmartWiFi in the SaaS model include:

Centralized Management:Providers can manage Wi-Fi networks for multiple customers from a single platform, ensuring consistent performance and security.

Scalability:The SaaS model allows providers to scale their services up or down based on demand, accommodating seasonal fluctuations or business growth.

Cost Efficiency:Customers pay only for the services they use, reducing upfront costs and making advanced Wi-Fi solutions more accessible.

Enhanced Features:SmartWiFi includes capabilities like automatic channel optimization, interference mitigation, and real-time monitoring, all delivered via the cloud.

This approach is particularly beneficial for small and medium-sized enterprises (SMEs) that lack the resources to manage complex Wi-Fi networks independently.

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.
