The statement isTrue. TheHuawei OptiXtrans DC908is specifically designed to support400GE (Gigabit Ethernet)services, making it a cutting-edge solution for high-capacity data center interconnects (DCI) and backbone networks.

Here’s why the DC908 supports 400GE:

High-Speed Transmission:The DC908 leverages advanced modulation techniques like DP-16QAM (Dual Polarization 16 Quadrature Amplitude Modulation) to achieve data rates of up to400G per wavelength.

Scalability:It can aggregate multiple 100GE or 200GE services into a single 400GE link, optimizing bandwidth utilization.

Low Latency:Designed for ultra-low latency, the DC908 ensures minimal delay for mission-critical applications like cloud computing, AI, and big data analytics.

Flexibility:Supports both OTN and Ethernet interfaces, enabling seamless integration into diverse network architectures.

The ability to support 400GE positions the DC908 as a future-proof solution for the growing demands of modern data centers and carrier networks.

The statement isTrue.Data Center Interconnect (DCI)networks are evolving towardmesh architectures, simplification, and intelligence to meet the growing demands of cloud computing, AI, and big data analytics.

Here’s how DCI is evolving:

Mesh Architecture:

Traditional point-to-point DCI links are being replaced bymesh topologies, which provide multiple paths between data centers.

This improves redundancy, load balancing, and fault tolerance, ensuring uninterrupted service even during failures.

Simplification:

Modern DCI solutions like theOptiXtrans DC908integrate multiple functions (e.g., optical modules, amplifiers, control units) into a single device, reducing complexity.

Automation tools likeNCE-Tstreamline operations, minimizing manual intervention and errors.

Intelligence:

AI-driven analytics enable real-time monitoring, predictive maintenance, and dynamic optimization of DCI networks.

Features likeoptical latency mapsandbandwidth visualizationhelp operators make informed decisions.

This evolution reflects the need for DCI networks to become more agile, efficient, and resilient in the face of increasing traffic volumes and diverse application requirements.

The statement isTrue. TheOSN 1800series is renowned for being theindustry’s highest-integrated 200G transmission solution, capable of supporting services ranging from64Kbps to 100GE.

Key features of the OSN 1800 include:

High Integration:The OSN 1800 combines multiple technologies (e.g., OTN, SDH, Ethernet) into a compact form factor, maximizing space efficiency.

Scalable Capacity:Supports up to200G per wavelength, enabling high-capacity transport for metro and access networks.

Service Flexibility:Can handle a wide range of services, from low-speed TDM (Time Division Multiplexing) circuits (e.g., 64Kbps) to high-speed Ethernet (e.g., 100GE).

Converged Architecture:Integrates OTN, SDH, and packet switching into a single platform, simplifying network operations and reducing costs.

These capabilities make the OSN 1800 ideal for applications like enterprise connectivity, mobile backhaul, and data center interconnects.

Campus OptiX (POL) saves investment in bothCapex (Capital Expenditure)andOpex (Operational Expenditure). Specifically:

Capex Savings:POL reduces costs associated with active equipment (e.g., switches, routers), cabling, and construction by using passive optical splitters and a simplified architecture.

Opex Savings:POL lowers operational costs due to its centralized management, reduced power consumption, and lower maintenance requirements compared to traditional Ethernet-based LANs.

Option Dis incorrect because it excludes savings from active equipment, which is a significant cost component in traditional networks.

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.

TheOptiXtrans DC908is a high-performance data center interconnect (DCI) solution that supports400GE (Gigabit Ethernet)services. This capability is critical for modern data centers requiring ultra-high-speed connectivity for applications like cloud computing, big data analytics, and artificial intelligence.

Key details:

400GE Support:The DC908 uses advanced line cards (e.g., MD02A) to provide native 400GE interfaces.
