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.
