Huawei Updated H19-102_V2.0 Exam Questions and Answers by arran

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.

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.

The Huawei OptiXtrans DC908 is designed for data center compatibility, including physical integration with IT racks. HCSA-Sales-Transmission & Access documents specify that the DC908 features a front air inlet and rear air outlet cooling design, aligning with standard data center rack airflow patterns (front-to-back). This ensures efficient thermal management in dense deployments, making the statement TRUE.

The main PON (Passive Optical Network) technologies include:

GPON (Gigabit PON) – ITU-T G.984 standard

10G-PON (XG-PON/XGS-PON) – ITU-T G.987/G.9807.1 standard

NG-PON2 (Next-Generation PON2) – ITU-T G.989 standard

However, 15G-PON is not an officially recognized PON standard. There is no such technology defined under ITU-T or IEEE for PON-based networks.

Thus, the correct answer is 15G-PON, as it does not exist in the PON technology family.
