Huawei H19-102_V2.0 Exam Dumps

A Passive Optical LAN (POL) network, as per HCSA-Sales-Transmission & Access, consists of:

OLT (Optical Line Terminal): The central device managing the network.

ODN (Optical Distribution Network): Passive infrastructure (e.g., fibers, splitters) connecting OLT to ONUs.

ONU (Optical Network Unit): The endpoint device at customer premises.

These are the core components of Huawei's POL (e.g., Campus OptiX), making the statement TRUE.

Campus networks today face several key challenges:

Hard to expand/upgrade cabling system -- Traditional Ethernet-based campus networks require extensive copper cabling, which is difficult to expand and upgrade, leading to higher costs and complexity.

Chimney networks hard to maintain -- Many legacy campus networks operate in a chimney-style architecture (vertical silos of network systems), making it difficult to manage and integrate different services.

Restriction of 100m makes network complex -- While Ethernet has a 100m distance limit, modern fiber-based Passive Optical LAN (POL) solutions overcome this restriction, making this less of a challenge today.

Devices are too large -- Modern networking equipment is compact and modular, making device size less of a concern in today's campus networks.

Thus, the correct answers are A and D.

Huawei's OptiXaccess brand encompasses a broader range of access network solutions, not just ONUs. HCSA-Sales-Transmission & Access materials describe OptiXaccess as including OLTs, ONUs, and related PON equipment for enterprise and residential access, not solely the ONU series. The statement's narrow scope is incorrect, making it FALSE.

Huawei's technical strengths, particularly for DCI and optical solutions like the DC908, resonate with technical-level customers (e.g., engineers, CTOs). Per HCSA-Sales-Transmission & Access:

Maximum bandwidth per wavelength (A): Huawei's in-house 800G oDSP chips enable industry-leading per-wavelength capacity, a key technical advantage.

Simplest O&M (B): Distributed Light Sensor technology simplifies optical-layer management with one-click and zero-touch deployment, reducing complexity.

Widest spectrum (C): Super C+L band support expands capacity to 220 wavelengths (11 THz), far exceeding traditional C-band (4 THz), a standout feature.

All options (A, B, C) are verified technical strengths.

The DC908's features, per HCSA-Sales-Transmission & Access, include:

Co-deployed with IT devices (A): Supports rack integration with IT equipment.

Front air inlet and rear air outlet (C): Matches data center cooling standards.

AC/HVDC/DC power supply (D): Offers flexible power options (AC, high-voltage DC, DC).

19-inch ETSI rack installation (B): While compatible with 19-inch racks, 'ETSI' typically implies European telecom standards (e.g., 21-inch), and DC908's primary focus is 19-inch IT racks; this is not a highlighted feature.

Thus, A, C, and D are correct.
