Huawei Optical Transport Network Solution Guide

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 to400G.

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.

ITU-T G.698 Standards for WDM

The correct answer isNetwork Doctor. TheNetwork Doctorfeature provides real-time monitoring, early warnings, and optimization capabilities to ensure high-quality network performance.

Here's how Network Doctor works:

Real-Time Monitoring:Tracks key performance indicators (KPIs) such as latency, jitter, packet loss, and bandwidth utilization.

Pre-Warning System:Detects anomalies and predicts potential issues before they impact services, enabling proactive intervention.

Link Optimization:Automatically adjusts network parameters to optimize link performance and prevent deterioration.

AI and Analytics:Leverages artificial intelligence and big data analytics to provideactionable insights and recommendations.

Other options:

Fiber Doctor:Focuses on physical fiber health rather than overall network quality.

Optical Doctor:Optimizes optical signal quality but does not monitor end-to-end network performance.

Service Doctor:Monitors specific services (e.g., IPTV, VoIP) but does not provide comprehensive network-wide insights.

ITU-T G.872 Standards for Optical Network Architecture

The correct answer includes all options:Home-WiFi, IPTV, High-Speed Internet, and Telephone. FTTH (Fiber-to-the-Home) solutions are designed to deliver a wide range of services over a single fiber connection, leveraging the high bandwidth and low latency of optical networks.

Home-WiFi:Provides wireless internet access within the home using Wi-Fi routers connected to the ONU.

IPTV:Delivers high-quality video streaming services, including live TV, Video on Demand (VoD), and interactive features.

High-Speed Internet:Offers broadband connectivity for web browsing, online gaming, andother data-intensive applications.

Telephone:Supports Voice over IP (VoIP) services, enabling voice communication over the fiber network.

FTTH is a converged solution that integrates these services into a unified platform, simplifying network management and enhancing user experience.

ITU-T G.984.x Standards for GPON

The correct answer isTTA. TheTTA boardisnota PCM (Pulse Code Modulation) board; it is typically used for other purposes, such as Ethernet switching or aggregation.

Here's an overview of the options:

DXM:A PCM board used for digital cross-connect and multiplexing in optical networks.

AT8:A PCM board that supports analog-to-digital conversion for voice and data services.

TTA: Not a PCM board; it is often used for Ethernet switching or aggregation in access networks.

FXSO12:A PCM board that provides interfaces for analog voice and data services.

PCM boards are essential for converting analog signals into digital format and vice versa, enabling efficient transmission over digital networks. The TTA board, however, serves a different purpose and is not classified as a PCM board.
