The statement that the lowest voltage drop is achieved when using CAT6 cable instead of Cat5 or

CAT5e is true about 802.3, Clause 33 Power over Ethernet. Power over Ethernet (PoE) is a technology

that allows electrical power to be delivered over Ethernet cables along with data signals. PoE is

defined by IEEE 802.3, Clause 33 and has several variants, such as PoE (802.3af), PoE+ (802.3at), and

PoE++ (802.3bt). PoE works by using a device called PSE (Power Sourcing Equipment) that injects

power into the Ethernet cable and a device called PD (Powered Device) that receives power from the

Ethernet cable. The PSE can be either an endpoint device, such as a switch or a router, or a midspan

device, such as an injector or a splitter, that is inserted between two Ethernet devices. The PD can be

any device that requires power, such as an access point, a camera, or a phone.

One of the factors that affects PoE performance is voltage drop, which is the reduction of voltage that

occurs as current flows through a cable due to its resistance. Voltage drop can cause power loss and

inefficiency in PoE systems, as well as damage to PDs if the voltage falls below their minimum

requirement. To minimize voltage drop, it is recommended to use high-quality cables with low

resistance and short length. Among the common types of Ethernet cables, CAT6 has the lowest

resistance and therefore the lowest voltage drop compared to Cat5 or CAT5e. CAT6 also has higher

bandwidth and data rate than Cat5 or CAT5e, making it more suitable for PoE

applications. Reference: 1, Chapter 7, page 263; 2, Section 4.4
