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.

The Huawei OptiXtrans DC908 is a Data Center Interconnect (DCI) solution tailored for high-

performance, low-latency, and simplified deployment in data center scenarios. While Huawei’s

optical solutions, including the DC908, are widely deployed globally, the specific claim of "620,000+

optical devices commercially used worldwide" is not explicitly documented as a key feature of the

DC908 in official HCSA-Sales-Transmission & Access materials. The DC908’s key features focus on

aspects like high capacity (e.g., 88T per fiber), low power consumption (35% lower than the industry

average), rapid commissioning (within 8 minutes), and cost-effective payback (within 1 year for self-

built networks). The figure of 620,000+ devices might pertain to Huawei’s broader optical portfolio,

but it is not a verified key feature specific to the DC908. Thus, the statement is FALSE in this context.

Reference: Huawei HCSA-Sales-Transmission & Access training materials, DC908 product datasheet.

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.

Reference: Huawei DC908 Hardware Design, HCSA-Sales-Transmission & Access datasheet.

The OptiXtrans DC908’s specifications in HCSA-Sales-Transmission & Access highlight:

Capacity 47% higher: DC908’s 88T/fiber exceeds the industry average (around 60T/fiber), a ~47%

increase, as derived from documented comparisons.

Power consumption 35% lower: At 0.13 W/G vs. the industry’s 0.2 W/G, it achieves a 35% reduction.

Both claims align with DC908’s key features, making the statement TRUE.

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 center

traffic.

✅ 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.

Huawei OptiXtrans DC908 Datasheet – Section: Application Scenarios

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.

DC908 features front air inlet and rear air outlet, per HCSA-Sales-Transmission & Access, for data

center compatibility. The negation is incorrect, making it FALSE.

eSight is Huawei’s network management system (NMS) designed to provide centralized

management for various network elements. In the context of the Campus OptiX solution, HCSA-

Sales-Transmission & Access documents confirm that eSight supports converged management of

both IP-based equipment (e.g., switches, routers) and POL components (e.g., OLTs, ONUs). This

capability enables unified monitoring, configuration, and fault detection across the hybrid IP+POL

architecture, enhancing operational efficiency. The statement is consistent with eSight’s documented

functionality, making it TRUE.

Reference: Huawei eSight NMS Overview, HCSA-Sales-Transmission & Access, Campus OptiX section.

Huawei’s Campus OptiX, based on POL technology, is tailored for various scenarios, including

airports. According to HCSA-Sales-Transmission & Access documents, the key advantages in the

airport scenario include:

Smart O&M (A): Campus OptiX leverages eSight NMS for intelligent operations and maintenance,

simplifying network management in large-scale environments like airports.

Up to 40km Coverage (C): POL’s passive optical architecture supports long-distance coverage (up to

40km), ideal for expansive airport campuses.

Ultimate Wi-Fi Experience (B): While Campus OptiX supports high-speed connectivity, this advantage

is more emphasized in scenarios like hotels or offices with Wi-Fi roaming features, not specifically

highlighted for airports.

Thus, A and C are the verified advantages.

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.
