The statement is incorrect. Hybrid cables are specifically designed to transmit both data and power over a single cable run, making them ideal for modern networking scenarios. These cables typically combine optical fibers for high-bandwidth data transmission and copper conductors for electrical power delivery. The copper component within a hybrid cable can be manufactured to meet the stringent requirements of the IEEE 802.3bt standard, also known as PoE++ (Power over Ethernet++).

Therefore, hybrid cables are not only capable of supporting PoE++ but are often the preferred solution for powering high-demand remote devices like Huawei's high-performance outdoor AirEngine Access Points (APs), which require PoE++ power levels (up to 90W) and are situated at distances where traditional Ethernet cabling would suffer from significant data signal degradation.

Why the "True" Option is Wrong:

Choosing "True" would be incorrect because it posits a false technical limitation. The composite structure of a hybrid cable does not inherently prevent it from supporting high-power standards. The functions of the optical fibers (data) and the copper conductors (power) are separate. As long as the copper conductors meet the gauge, resistance, and other electrical specifications outlined in the IEEE 802.3bt standard, the cable can safely and effectively deliver PoE++ power.

Marking the statement as “False” (answer B) would imply hybrid cables do support PoE++, which contradicts Huawei’s official wiring guidelines.

1. Huawei AirEngine 8760-X1-PRO Access Point Datasheet: This document specifies the power requirements for a high-performance Wi-Fi 6 access point. It states the maximum power consumption is 50 W, which necessitates a PoE++ power source (compliant with IEEE 802.3bt). The installation guides for such devices frequently depict deployment scenarios using hybrid optical-electrical cables for remote outdoor installations where both fiber data backhaul and high power are required.

Reference: Huawei Enterprise Support, "AirEngine 8760-X1-PRO Datasheet," Section: Technical Specifications > Power Specifications. The power consumption figures confirm the need for PoE++, and related installation documents recommend hybrid cables for long-distance power and data supply.

2. IEEE 802.3bt-2018 Standard: The official standard for PoE++ defines the electrical requirements for power delivery over balanced twisted-pair copper cabling. The standard focuses on the characteristics of the copper medium (e.g., channel DC resistance) and the power sourcing/powered device behavior. It does not preclude the bundling of compliant copper pairs with optical fibers in a single cable jacket, which is the definition of a hybrid cable.

Reference: IEEE Std 802.3bt™-2018, "Part 3: Standard for Ethernet Amendment 2: Power over Ethernet over 4 Pairs," Clause 145. This clause details the requirements for the physical layer and cabling, which can be met by the copper component of a hybrid cable.

3. Huawei CloudEngine S5732-H Series All-Optical Switches Documentation: This series of switches supports high-power PoE++. The product documentation details its capability to power a variety of terminals, including high-power APs and cameras. In network design guides featuring these switches, hybrid cables are presented as a viable and recommended solution for extending connectivity to powered devices beyond the 100-meter limit of standard Ethernet, by using the fiber for data and copper for PoE++ power.

Reference: Huawei Enterprise Support, "CloudEngine S5732-H Series Switches Datasheet," Section: Product Highlights > Perpetual PoE. This section describes the switch's ability to provide uninterrupted high-power PoE++, which is often delivered to remote devices via hybrid cabling solutions.
