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.

Technical-level customers (e.g., engineers) in DCI scenarios face high costs (bandwidth, equipment) and difficult O&M (complex planning, maintenance), as per HCSA-Sales-Transmission& Access. DC908 addresses these with low per-bit costs and simplified deployment, making the statement TRUE.

Fiber optic cables in POL and DCI solutions have a lifecycle of 30 years, per HCSA-Sales-Transmission & Access, due to their durability and passive nature, making B correct.

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.

The Huawei OptiXtrans DC908 is a high-performance Data Center Interconnect (DCI) solution designed specifically for DCI applications.

✅High-capacity transmission – Supports 800G per wavelength to handle large-scale data centertraffic.✅Simplified deployment – Uses intelligent management tools for plug-and-play operations.✅High reliability – Supports multi-layer protection and low latency for critical data center connectivity.

Thus, the correct answer is TRUE.

The DC908 is designed for DCI with IT compatibility. HCSA-Sales-Transmission & Access confirms it supports co-deployment with IT devices in the same rack, featuring a 2U form factor, front-to-rear airflow, and rack-standard dimensions (e.g., 19-inch ETSI). The statement’s negation is incorrect, making it FALSE.

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.

Difficult O&M is a pain point in DCI, per HCSA-Sales-Transmission & Access. Inexperienced engineers struggling with network planning and CT (communication technology) device maintenance exacerbate this, aligning with DC908’s simplified O&M focus, making the statement TRUE.

Huawei’s Campus OptiX solution is a multi-service network capable of delivering all major digital services over a single optical fiber infrastructure:

✅Internet – High-speed broadband access via fiber.✅Telephone – Supports traditional POTS and VoIP services.✅Wi-Fi – Provides fiber backhaul for wireless access points (APs).✅TV (IPTV & CATV) – Distributes video services efficiently over the same network.

Since Campus OptiX can handle all these services, the correct answer is E (All of the above).

Huawei’s Campus OptiX solution consists of:

✅OLT (Optical Line Terminal) – Manages the network and distributes signals.✅ODN (Optical Distribution Network) – Passive fiber infrastructure for connectivity.✅ONU (Optical Network Unit) – Delivers services to end devices.✅eSight (Management Software) – Provides centralized monitoring and management of the Campus OptiX network.

Thus, the correct answer is B (OLT + ODN + ONU + eSight).

Passive Optical Networks (PON) use a Point-to-Multipoint (P2MP) topology where a single Optical Line Terminal (OLT) connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) using passive splitters.

✅Efficient Bandwidth Sharing – A single fiber from the OLT is split among multiple users, reducing fiber deployment costs.

✅Scalable and Cost-Effective – Supports higher user density with minimal fiber usage.

Since PON does not follow a Point-to-Point (P2P) model, the correct answer is P2MP.

The Huawei EA5800-X2 is a compact OLT model in the SmartAX series, used in PON deployments like Campus OptiX. HCSA-Sales-Transmission & Access documentation specifies that it supports 2 service-card slots, balancing capacity and size for small-to-medium scenarios. Thus, B is the correct answer.

In a Passive Optical LAN (POL), the Optical Distribution Network (ODN) consists entirely of passive optical components such as splitters, connectors, and fibers. These components do not require external power, making them fully passive.

The ODN in POL follows Point-to-Multipoint (P2MP) architecture using passive splitters, ensuringsignal distribution without electrical conversion. Since no active components are present in the ODN, it remains maintenance-free and energy-efficient.

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.

DC908’s key features, per HCSA-Sales-Transmission & Access, include:

Payback within 1 year (A): A core economic benefit.

Automatic Commissioning within 8 minutes (D): Simplifies deployment.

30%+ higher performance (B): Capacity is 47% higher, but "performance" isn’t phrased this way.

Double stability (C): Not a specific claim.

Thus, A and D are correct.

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.

DCI stands for Data Center Interconnect, a term widely used in the industry and explicitly defined in HCSA-Sales-Transmission & Access materials. It refers to technologies (e.g., Huawei OptiXtrans DC908) that link multiple data centers for high-speed, low-latency data transfer. The statement is accurate, making it TRUE.

Customer pain points in transmission and access contexts (e.g., DCI, POL) are well-documented in HCSA-Sales-Transmission & Access:

High cost (B): Rising bandwidth and leased line costs are a universal concern across industries.

Difficult O&M (D): Complex operations and maintenance challenge customers, especially in DCI or legacy LANs.

High Availability (A): This is a requirement, not a pain point; customers seek it rather than suffer from it.

Frequent stock transactions (C): A financial sector need, not a general pain point in transmission/access.

Thus, B and D are the verified pain points.

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 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.

Finance industry DCI pain points, per HCSA-Sales-Transmission & Access, include:

Increased leased line prices: A key driver for self-built networks.
