The statement isTrue. TheHuawei EA5800 OLTemploys adistributed architectureto deliver superior performance and scalability. In a distributed architecture, processing tasks are divided among multiple components, reducing bottlenecks and improving overall system efficiency. This design allows the EA5800 to handle high-density subscriber traffic with low latency and high reliability, making it ideal for carrier-grade deployments.

Key benefits of the distributed architecture include:

High Performance Switching:Supports large-scale data forwarding with minimal delay.

Scalability:Easily accommodates additional subscribers and services.

Redundancy:Enhances fault tolerance and network availability.

TheNCE-T (Network Cloud Engine - Transport)is a modular platform that supports multiple functional modules for managing optical transport networks. Here’s an analysis of each option:

Analysis Module:Provides AI-driven analytics for network performance monitoring, fault prediction, and optimization.

Forwarding Module:The NCE-T does not include a forwarding module, as this function is handled by the underlying network devices (e.g., routers, switches).

Management Module:Handles device configuration, fault monitoring, and performance management.

Control Module:Provides centralized control over network resources, enabling features like automatic service provisioning and policy enforcement.

Thus, the correct answers areA (Analysis module), C (Management module), and D (Control module).

The correct answer is1. TheOptiXtrans DC908is designed to support high-density configurations, allowing an8x200G (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.

TheEA5800-X2is a compact Optical Line Terminal (OLT) designed for small and medium-sized networks. One of its key features is the support fordual AC input interfaces, which enhances power redundancy and reliability.

The correct answer isEG8080P. Afaceplate ONUis a compact Optical Network Unit designed to be mounted on a wall or faceplate, typically used in Fiber-to-the-Room (FTTR) or Fiber-to-the-Desk (FTTD) scenarios. TheEG8080Pis specifically designed for such applications, providing high-speed internet, voice, and video services in a small form factor.

Other options:

EG8240P:A standard home gateway ONU, not a faceplate model.

EG8145V5:A residential gateway ONU, not suitable for faceplate mounting.

EG8020P:A business-class ONU, but not a faceplate model.

The minimum protection switching time forLink-layer Type B Switchingin GPON is50ms. Type B protection involves protecting the fiber link between the OLT and the splitter by providing redundant fibers. In the event of a fiber failure, the system switches to the backup fiber within 50ms to ensure minimal service disruption. This fast switching time is critical for maintaining high availability and reliability in GPON networks.

3s, 3min, 1min:These times are far too long for protection switching in modern optical networks, which require near-instantaneous recovery to meet SLA (Service Level Agreement) requirements.
