Which of the following optical modules are used in commercial cases currently?
Optical modules are categorized based on their transmission distance and power budget. The most commonly used classes in commercial deployments are:
Class B+:Supports distances up to 20 km and is widely used in urban and suburban areas.
Class C+:Supports distances up to 40 km and is suitable for medium-range deployments.
Class D:Supports distances up to 60 km and is ideal for long-haul connections in remote areas.
ClassesEandFare either outdated or not commercially viable due to their limited use cases.

Which of the following devices can be managed by the NCE-T?
The correct answer isOTN Devices. TheNCE-T (Network Cloud Engine for Transport)is specifically designed to manageOTN (Optical Transport Network)devices, providing centralized control, monitoring, and automation for optical transport networks.
Here's how NCE-T supports OTN devices:
Centralized Management:Provides a unified platform for managing OTN devices across the network, simplifying operations and reducing complexity.
Automation:Automates tasks like service provisioning, fault detection, and performance optimization, improving efficiency and reducing manual errors.
Real-Time Monitoring:Tracks key metrics like bandwidth utilization, latency, and error rates to ensure optimal network performance.
Service Orchestration:Coordinates the delivery of services like IPTV, VoIP, and broadband internet across multiple OTN devices.
Other options:
MxU series Devices:Managed by access network solutions like the NCE-Access.
OLT series Devices:Managed by GPON/FTTx solutions like the NCE-FAN.
MSTP Devices:Managed by legacy SDH/SONET solutions, not NCE-T.
The NCE-T's focus on OTN devices reflects its role in modernizing optical transport networks for high-capacity, low-latency applications.

OptiXtrans products include: E9600, OSN 1800, 1X908, and E5800.
The statement isFalse. While theOptiXtrans E9600andOSN 1800are part of Huawei's optical transmission portfolio, the1X908andE5800are not included under the OptiXtrans product line.
Here's a clarification:
OptiXtrans E9600:A series of optical transmission devices designed for backbone, metro, and access networks.
OSN 1800:A compact optical transport platform for enterprise and carrier-grade applications.
1X908:This is not a recognized product in Huawei's optical transmission portfolio.
E5800:Refers to a different product line, typically associated with access networks rather than optical transmission.
The confusion may arise from overlapping product names, but the OptiXtrans series specifically focuses on optical transmission solutions.
