3 Power Sourcing Equipment (PSE) in IEEE 802.3 Standard
7 --------
9 Power Sourcing Equipment (PSE) is essential in networks for delivering power
10 along with data over Ethernet cables. It usually refers to devices like
14 PSE vs. PoDL PSE
15 ----------------
17 PSE in the IEEE 802.3 standard generally refers to equipment that provides
18 power alongside data over Ethernet cables, typically associated with Power over
19 Ethernet (PoE).
21 PoDL PSE, or Power over Data Lines PSE, specifically denotes PSEs operating
22 with single balanced twisted-pair PHYs, as per Clause 104 of IEEE 802.3. PoDL

27 ---------------------------------------------
29 Key addenda to the IEEE 802.3-2018 standard relevant to power delivery over
30 Ethernet are as follows:
32 - **802.3af (Approved in 2003-06-12)**: Known as PoE in the market, detailed in
34 - **802.3at (Approved in 2009-09-11)**: Marketed as PoE+, enhancing PoE as
36 - **802.3bt (Approved in 2018-09-27)**: Known as 4PPoE in the market, outlined
38 - **802.3bu (Approved in 2016-12-07)**: Formerly referred to as PoDL, detailed
39   in Clause 104. Introduces Classes 0 - 9. Class 9 PoDL PSE delivers up to ~65W
