H19-102_V2.0 Questions and Answers

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.

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.

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.

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.

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.

POL’s passive optical design (e.g., ODN with splitters) eliminates active equipment, reducing power consumption by up to 50% vs. active Ethernet, per HCSA-Sales-Transmission & Access,making the statement TRUE.

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.

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

Commissioning within 8 minutes (C): Critical for rapid deployment in finance.

Double stability (A): Not a specific metric; stability is enhanced but not quantified as "double."

Latency <10 ps (B): Latency is low but not specified as picoseconds (ps); more likely microseconds (µs).

Thus, C is correct.

POL stands for Passive Optical LAN in Huawei’s context, per HCSA-Sales-Transmission & Access. It applies PON technology to enterprise campuses, replacing traditional LANs with fiber-based, passive solutions. Other options (A, B, C) are unrelated, making D correct.

Financial customers, particularly in Data Center Interconnect (DCI) scenarios, face specific challenges that Huawei’s solutions like the OptiXtrans DC908 address. According to HCSA-Sales-Transmission & Access documentation, key pain points for financial customers include:

Financial disaster recovery (B): Financial institutions require robust disaster recovery mechanisms to ensure data integrity and business continuity, a critical need in DCI scenarios.

Financial network attacks (C): Cybersecurity is a major concern due to the sensitive nature offinancial data, making network security a top priority.

Increased leased line prices (D): Rising costs of leased lines push financial customers toward cost-effective self-built networks, a pain point Huawei addresses with solutions like DC908.

Frequent stock transactions (A): While important, this is a business requirement rather than a technical pain point related to transmission or access infrastructure. It’s not listed as a primary concern in the context of DCI or POL solutions for financial customers.

Thus, B, C, and D are the verified pain points.

In Data Center Interconnect (DCI) scenarios, high-level customers—such as large enterprises, ISPs, and financial institutions—face significant challenges, as outlined in HCSA-Sales-Transmission & Access documentation. The two major pain points are:

High costs: DCI traffic grows rapidly (over 50% annually), and bandwidth costs often double every two years, making cost management a critical issue.

Difficult O&M (Operations & Maintenance): Traditional DCI setups involve complex network planning and maintenance, often requiring skilled engineers, which increases operational complexity.

Huawei’s OptiXtrans DC908 addresses these with lower per-bit costs (e.g., 88T/fiber capacity) and simplified O&M (e.g., one-click deployment). The statement aligns with documented customer pain points, making it TRUE.

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 All-Optical PON Architecture, as part of Huawei’s POL and Campus OptiX solutions, replaces traditional active Ethernet LANs with passive optical components, yielding significant engineering savings. According to HCSA-Sales-Transmission & Access documentation:

Cabling Space (A): Fiber optic cables are thinner and lighter than copper, reducing cabling space requirements.

IT Room Space (B): Passive architecture eliminates the need for intermediate active equipment (e.g., switches), freeing up IT room space.

Power Consumption (C): Passive components (e.g., splitters) require no power, significantly lowering energy use compared to active Ethernet setups.

Since all these aspects (A, B, C) are documented benefits, "All above" (D) is the correct answer.

Huawei's Campus OptiX (POL) solution uses a single optical fiber to carry multiple services simultaneously, including:

✅Wi-Fi – Fiber backhaul for wireless access points.✅Internet – High-speed broadband access.✅Telephone (VoIP/POTS) – Voice services over optical fiber.✅TV (IPTV, CATV) – Video transmission over the same infrastructure.

Since optical fiber has high bandwidth and low latency, it can efficiently transmit all these services using different wavelengths or logical VLANs.

Thus, the correct answer is 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.

POL’s scenarios, per HCSA-Sales-Transmission & Access, include:

Dormitory in University (A): High-bandwidth campus needs.

Guest room in Hotel (C): Fiber-to-room deployments.

Wards in hospital (D): Reliable, scalable connectivity.

Apartment (B): More residential FTTH, less POL-focused.

Thus, A, C, and D are correct.

The finance industry heavily relies on DCI solutions for data replication, high availability, and disaster recovery. Key pain points include:

✅Increased leased line prices – Financial institutions require dedicated high-bandwidth connections, and leased line costs continue to rise.

✅Financial disaster recovery – To meet compliance regulations and business continuity requirements, banks and financial firms must deploy redundant DCI networks for real-time data backup and disaster recovery.

Thus, the correct answer is TRUE.
