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.

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 isMD02A. TheMD02A boardin theOptiXtrans DC908platform supports400G per wavelength, enabling high-capacity data transmission for backbone and core networks.

Key features of the MD02A board include:

High-Speed Transmission:Supports data rates up to400G per wavelength, leveraging advanced modulation techniques like DP-16QAM.

Flexibility:Compatible with various network architectures, including OTN, WDM, and Ethernet.

Scalability:Can be integrated into existing networks to boost capacity without requiring a complete overhaul.

Efficiency:Optimizes spectral efficiency, maximizing the utilization of available fiber resources.

Other options:

MD02:An earlier version of the board, typically supporting lower data rates.

MS04:Focuses on mid-range applications, not 400G.

N602:Designed for access networks rather than high-speed backbone transmission.
