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

The Huawei OptiXtrans DC908 is designed for flexible deployment in different data center environments. It supports:

✅197 ETSI rack compatibility – Ensuring industry-standard installation options.✅600mm, 800mm, 1000mm, and 1200mm depth installation – Making it adaptable to different rack sizes for seamless integration into various data centers.

Thus, the correct answer is TRUE.

PON, or Passive Optical Network, is a telecom technology that uses fiber optics and passive components (e.g., splitters) to deliver broadband access. According to HCSA-Sales-Transmission & Access documentation, PON operates in a point-to-multipoint (P2MP) topology, where a single Optical Line Terminal (OLT) at the service provider’s end connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) at customer premises via a shared optical distribution network (ODN). This distinguishes it from point-to-point (P2P) systems, which dedicate a fiber per user. The statement accurately describes PON’s definition and architecture, making it TRUE.

DCI is Data Center Interconnect, per HCSA-Sales-Transmission & Access. The negation is incorrect, making it FALSE.

Campus OptiX supports GPON (2.5Gbps) and evolves to 10GPON (10Gbps) using the same OLT and ODN, per HCSA-Sales-Transmission & Access, ensuring future-proofing, making the statement TRUE.

The highlights of "Ultra broadband & High Integration" pertain to Huawei’s advanced transmission solutions, such as the OptiXtrans DC908, designed for DCI scenarios. According to HCSA-Sales-Transmission & Access materials:

Hybrid photoelectric integration (B): This feature integrates optical and electrical components, reducing complexity and improving efficiency, a hallmark of Huawei’s high-integration designs.

9.6T/2U (C): The DC908 delivers an industry-leading capacity of 9.6 terabits per second in a compact 2U form factor, emphasizing ultra-broadband capability and space efficiency.

100G~800Gbit@per X (D): This refers to the flexible, scalable bandwidth per port (ranging from 100G to 800G), a key feature for ultra-broadband applications in DCI.

Hardware redundancy (A): While important for reliability, it is not specifically highlighted under "Ultra broadband & High Integration" but rather under stability or resilience features.

Thus, B, C, and D are the verified highlights.

This statement aligns with the Huawei OptiXtrans DC908’s key specifications in HCSA-Sales-Transmission & Access documents:

88T/fiber vs. 60T/fiber: DC908 achieves 88 terabits per fiber using Super C+L band, surpassing the industry’s 60T/fiber average.

6.4T/U vs. 3.6T/U: It delivers 6.4T per rack unit (U), higher than the industry’s 3.6T/U, optimizing space efficiency.

Lowest per-bit cost: High capacity and efficiency reduce the cost per bit, a core DC908 selling point.

Power consumption (0.13 W/G vs. 0.2 W/G): DC908’s 0.13 watts per gigabit is 35% lower than the industry’s 0.2 W/G, as verified.

The statement is fully accurate, making it TRUE.

A self-built Data Center Interconnect (DCI) provides several advantages:

✅High Efficient O&M – With self-built DCI, enterprises have full control over network monitoring, fault management, and performance optimization, reducing dependency on external providers.

✅Service Rollout on Time – Unlike leased lines, a self-built DCI network allows rapid service deployment without waiting for telecom operators, improving efficiency.

❌Guaranteed Quality – While a self-built network offers more control, it does not always guarantee quality compared to carrier-grade leased lines with SLAs (Service Level Agreements).

Thus, the correct answer is A and C.

In education (e.g., universities), Campus OptiX advantages, per HCSA-Sales-Transmission & Access, include:

1 Day Service Ready (A): Rapid deployment via POL.

100Mbps @ Everywhere (C): High bandwidth across campus.

1 Terminal @ 1 Room (B): More hotel-specific; education focuses on coverage.

Thus, A and C are correct.

Passive Optical LAN (POL) is an all-optical enterprise networking solution comprising Optical Line Terminals (OLT) and Optical Network Units (ONU). In office scenarios, Huawei’s Campus OptiX POL solution allows flexibility in deployment. Official HCSA-Sales-Transmission & Access documents confirm that OLTs and ONUs can be sold independently based on customer needs, such as upgrading existing infrastructure or deploying specific components in a phased approach. For example, an office might procure an OLT to centralize management while adding ONUs later to expand coverage. This modularity supports tailored solutions, making the statement TRUE.

Campus OptiX (IP+POL) saves investment, per HCSA-Sales-Transmission & Access:

Capex: Reduces costs for active equipment (fewer switches), cabling (fiber vs. copper), and construction (simplified architecture).

Opex: Lowers power, maintenance, and operational costs due to passive design.

Option C fully captures these savings, making it correct.

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.

WebGUI supports single-device management (e.g., DC908), per HCSA-Sales-Transmission & Access, offering configuration and monitoring, making the statement TRUE.

Huawei’s Campus OptiX (IP+POL) solution integrates IP and Passive Optical LAN technologies to deliver value to enterprise customers. Per HCSA-Sales-Transmission & Access documentation:

Converged O&M (A): The solution uses eSight NMS to manage both IP and POL equipment, providing unified operations and maintenance, reducing complexity.

Green and Efficient Engineering (B): POL’s passive nature saves power, cabling, and space, while simplified deployment (e.g., fewer layers) enhances engineering efficiency.

Ultra-Broadband (C): While Campus OptiX supports high bandwidth (e.g., GPON to 10GPON evolution), this is a technical capability rather than a distinct "value" highlighted in sales materials, which focus more on O&M and engineering benefits.

Thus, A and B are the verified values.
