Huawei HCSA-Presales-Transmission & Access H19-315 Exam Questions

Answer : A, B, C, D, E

TheFTTH (Fiber-to-the-Home)network consists of several key components that work together todeliver high-speed connectivity to end-users:

ONU/ONT (Optical Network Unit/Terminal):Customer-side device that converts optical signals into electrical signals for end-user devices.

OLT (Optical Line Terminal):Central device located at the service provider's premises, managing communication with multiple ONUs.

Splitter:Passive optical device that divides the signal from the OLT into multiple paths for distribution to ONUs.

NMS (Network Management System):Software platform (e.g., eSight) for centralized monitoring and management of the FTTH network.

ODF (Optical Distribution Frame):Infrastructure component used for organizing and connecting optical fibers.

Each of these components plays a critical role in ensuring efficient and reliable FTTH deployments.

In asafe city scenario, outdoor monitoring is a critical requirement. Huawei recommends usingoutdoor monitoring ONTslike theEG8084PandPowerCube500for such deployments. These devices are ruggedized and designed to operate in harsh environmental conditions, making them ideal for outdoor surveillance applications.

While indoor monitoring ONTs and pre-connection ODN are useful in other scenarios, they are not specifically optimized for outdoor safe city deployments. Similarly, small and medium OLTs like the EA5801 and EA5800-X2 are suitable for smaller-scale networks but are not directly related to the safe city use case.
