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.

eSight is Huawei’s Network Management System (NMS) for Campus OptiX, managing IP and POL equipment, per HCSA-Sales-Transmission & Access. It provides converged O&M, making the statement TRUE (YES).

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.

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.

In the hotel scenario, Huawei’s Campus OptiX (POL-based) offers tailored advantages, as per HCSA-Sales-Transmission & Access:

Best TCO (B): POL reduces cabling, power, and maintenance costs, delivering the best Total Cost of Ownership compared to traditional LANs.

1 Fiber for 1 Room (C): The solution supports a fiber-to-the-room architecture, providing high bandwidth and scalability for guest rooms.

Wi-Fi "0" Interrupt (A): While POL supports excellent Wi-Fi (e.g., via ONUs with Wi-Fi 6), "zero interrupt" is not a specifically highlighted advantage in hotel scenarios; it’s more emphasized in office roaming contexts.

Thus, B and C are the verified advantages.

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 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.
