• 16:4016:40, 1 May 2023 diff hist +51 100 Gigabit Ethernet →100G interface types: Cisco now says 100G-SRBD is good for 150m on OM5 fiber.

6 January 2023

• 16:3416:34, 6 January 2023 diff hist +141 100 Gigabit Ethernet →100G interface types: Add cross-references between 100G-SR2-BiDi and 100G-SR1.2; note their incompatibility.

• 21:5521:55, 7 December 2022 diff hist 0 Terabit Ethernet →400G port types: DR4-2 uses 8 (4 pairs) of fiber.

22 November 2022

• 16:4316:43, 22 November 2022 diff hist +82 Tesla Model 3 Add SR DC and AC charging info

16 September 2022

• 14:1014:10, 16 September 2022 diff hist +1,629 100 Gigabit Ethernet →100G interface types: Add 100G-SR1.2. Standard is unclear so far, leave it as a question.

1 June 2022

• 15:1215:12, 1 June 2022 diff hist 0 Terabit Ethernet →400G port types: 400G-KR8 uses 8 lanes (it has 8 media after all).
• 15:1115:11, 1 June 2022 diff hist +6 100 Gigabit Ethernet Split out PAM4 x2 multiplier in the generational line rate calculations. This is to try to make it clear that the "2" in SR2 corresponds to the 4x multiplier; PAM4 adds a x2 multiplier to give us the line rate.
• 15:0615:06, 1 June 2022 diff hist +11 Terabit Ethernet Split out PAM4 x2 multiplier in the generational line rate calculations. This is to try to make it clear that the "4" in LR4 corresponds to the 4x multiplier; PAM4 adds a x2 multiplier to give us the line rate.

13 March 2022

• 18:5018:50, 13 March 2022 diff hist 0 FLAC →File structure: The magic number has a lower case 'f' (so says the referenced source as well my FLACs).

9 March 2022

• 19:4419:44, 9 March 2022 diff hist +17 Terabit Ethernet →400G port types: XDR4 is also commonly called DR4+

8 March 2022

• 18:5618:56, 8 March 2022 diff hist −6 Terabit Ethernet →200G port types: CR2: remove emphasis (bold) from connectors here too.
• 18:5518:55, 8 March 2022 diff hist −15 Terabit Ethernet →200G port types: : CR4: no need to repeat the connector (transceiver form factor) in the transceiver module column. Also remove emphasis (bold) from the available connectors.
• 18:5418:54, 8 March 2022 diff hist −16 Terabit Ethernet →400G port types: CR4: no need to repeat the connector (transceiver form factor) in the transceiver module column. Also remove emphasis (bold) from the 3 available connectors.
• 18:5118:51, 8 March 2022 diff hist +44 Terabit Ethernet →400G port types: Fill in a few known transceiver modules (form factors) for a few standards.

21 January 2022

• 18:4318:43, 21 January 2022 diff hist 0 10 Gigabit Ethernet →Physical layer modules: Move 10G-PR (20km) between LR (10km) and ER (4km)
• 18:4218:42, 21 January 2022 diff hist 0 10 Gigabit Ethernet →Physical layer modules: Move MM (shorter range) rows above SM (higher ranges) in the table. 10GBASE-SW is problematic (out of order) because it shares Notes with the other *W standards.
• 18:2618:26, 21 January 2022 diff hist 0 10 Gigabit Ethernet →Physical layer modules: Move backplane and axial (very short reach) rows to the top of the table.
• 18:1418:14, 21 January 2022 diff hist 0 Terabit Ethernet →400G port types: Move VR4 and SR4 (MM) up above all the SM (and longer reach) rows.
• 18:1218:12, 21 January 2022 diff hist 0 100 Gigabit Ethernet →{{Anchor|Connectors}}40G interface types: Move SWDM4 up near SR4 and SR2-BiDi
• 18:1018:10, 21 January 2022 diff hist 0 100 Gigabit Ethernet →100G interface types: Move backplane standards to the top of the table(s)
• 18:0718:07, 21 January 2022 diff hist 0 100 Gigabit Ethernet →{{Anchor|Connectors}}40G interface types: Move backplane standards to the top of the table.
• 18:0318:03, 21 January 2022 diff hist 0 25 Gigabit Ethernet →25 Gigabit Ethernet: Move backplane standards to the top of the table.
• 18:0218:02, 21 January 2022 diff hist 0 25 Gigabit Ethernet →50 Gigabit Ethernet: Move backplane standards to the top of the table.

29 December 2021

• 15:1815:18, 29 December 2021 diff hist +64 BMW i4 →Models: US (and presumably all N. America) models come with a J1772 connector.

8 December 2021

• 19:0319:03, 8 December 2021 diff hist +31 Terabit Ethernet →400G port types: Add phase-out/current text to generation headers (making what is currently shown in formatting explicit/in words)
• 19:0019:00, 8 December 2021 diff hist +29 Terabit Ethernet →200G port types: Add phase-out/current text to generation headers (making what is currently shown in formatting explicit/in words).
• 18:5018:50, 8 December 2021 diff hist 0 m Terabit Ethernet →200G port types: Fix a rowspan
• 18:4718:47, 8 December 2021 diff hist −286 Terabit Ethernet →200G port types: Restore Media counts and one lambda count (all lost on 14 November).
• 18:3718:37, 8 December 2021 diff hist +585 Terabit Ethernet →200G port types: Restore generation headers: they're all 200G, the difference is the signaling rate so show the latter rather than reiterating the former. Restore 1st generation (8x25G, only 200GAUI-8). Add a ref that talks about 200GAUI-8
• 18:0918:09, 8 December 2021 diff hist −339 Terabit Ethernet →200G port types: Remove the Status column: there's no need for a column whose content is the same for every row.

22 October 2021

• 20:4520:45, 22 October 2021 diff hist +500 Terabit Ethernet →200G port types: Organize entries similar to the 100G (and now 400G) port types: by generation.

19 October 2021

• 15:1915:19, 19 October 2021 diff hist +493 Terabit Ethernet →400G port types: Organize entries similar to the 100G port types: by generation.
• 14:4314:43, 19 October 2021 diff hist −124 100 Gigabit Ethernet →100G interface types: Remove symbol rate info from VR1 and SR1: it's redundant (4th gen header has this info).
• 14:3914:39, 19 October 2021 diff hist +4 100 Gigabit Ethernet →100G interface types: Change color of 4th generation separator to green (success) - most of the standards are "current".

5 August 2021

• 21:0621:06, 5 August 2021 diff hist −16 10 Gigabit Ethernet →Physical layer modules: Switch reach to m (from km). At least I find it much easier (more intuitive) to convert 10000 to 10km than to convert 0.01 to 10m.

26 May 2021

• 15:2615:26, 26 May 2021 diff hist −497 100 Gigabit Ethernet →100G interface types: Remove extra "3rd generation" separator row (accidentally?) added on May 21st (it was added in the middle of the 2nd gen standards).
• 14:5814:58, 26 May 2021 diff hist +5 100 Gigabit Ethernet →{{Anchor|Connectors}}40G interface types: Move MSA statement to Standard column here too.
• 14:4914:49, 26 May 2021 diff hist −524 100 Gigabit Ethernet →100G interface types: Move "MSA" in the Standard column - to make it easier to differentiate IEEE vs. MSA vs. truly proprietary (vendor-specific)
• 14:4214:42, 26 May 2021 diff hist −15 Terabit Ethernet →400G port types: Say "MSA" in the Standard column - to make it easier to differentiate IEEE vs. MSA vs. truly proprietary (vendor-specific)
• 14:2514:25, 26 May 2021 diff hist +1,925 100 Gigabit Ethernet →100G interface types: Add 100G-LR1-20, -ER1-30, and ER1-40

• 14:1314:13, 26 May 2021 diff hist +314 Terabit Ethernet →400G port types: Add FR4 MSA spec reference
• 14:0914:09, 26 May 2021 diff hist 0 Terabit Ethernet →400G port types: Fix ZR column ordering (messed up in previous edit)
• 14:0714:07, 26 May 2021 diff hist +531 Terabit Ethernet →400G port types: Add 400G-LR4-10
• 13:5013:50, 26 May 2021 diff hist +211 Terabit Ethernet →400G port types: Add 400G-XDR4 (proprietary 2km version of DR4).

• 15:5015:50, 5 May 2021 diff hist +8 Terabit Ethernet Apply Zac67's recent change on the 100G page/table here too: say "wavelengths" in the lambdas tooltip (not everyone knows what lambdas are).
• 15:4815:48, 5 May 2021 diff hist +4 100 Gigabit Ethernet →{{Anchor|Connectors}}40G interface types: Apply Zac67's recent change to the 40G table too: say "wavelengths" in the lambdas tooltip.
