Removed Redirection Notice

I have removed the label at the top that states "RJ45" redirects here. For the generic 8P8C modular connector, see 8P8C. For the Registered Jack (RJ) wiring standard, see Registered jack.

Reason: The RJ45 article does not redirect here. CraigMatthews 01:12, 12 Dec 2009 (UTC)

Rename/move to Ethernet over twisted-pair

@Burt Harris: IMHO, that move is in error. "Twisted-pair" is a compound adjective that requires a noun, so it should be either "Ethernet over twisted pair" or "Ethernet over twisted-pair cabling". --Zac67 (talk) 07:41, 28 January 2021 (UTC)[reply]

Zac67 is correct. See Compound modifier. ~Kvng (talk) 15:11, 31 January 2021 (UTC)[reply]

Cat 7

Why it does not have the Cat7 in comparison table? — Preceding unsigned comment added by Daya Kathir (talk • contribs) 12:17, 9 May 2021 (UTC)[reply]

@Daya Kathir: Please try to use the New section feature on top to create a new topic section. Cat 7 isn't listed because there's no Ethernet-over-twisted-pair variant that requires it – it's backwards compatible with Cat 6 but not with Cat 6A. Cat 7 was intended for 10GBASE-T but requires special/exotic termination while the somewhat younger Cat 6A doesn't. Also, Cat 7 is popular in Europe and other countries but virtually non-existent in the US. --Zac67 (talk) 12:59, 9 May 2021 (UTC)[reply]

Probable Error in the table

Hello all.

I beleive that in table "Comparison of twisted-pair-based Ethernet physical transport layers (TP-PHYs)"

There is maybe a mistake: 100BASE-T1 -> Encoding = 4B3B -> I beleive it's 4B3T

Best regards Haarkon (talk) 09:07, 20 September 2024 (UTC)[reply]

IEEE 802.3 calls that "4B/3B", even if it uses ternary symbols – see clause 96.3.3. --Zac67 (talk) 12:34, 20 September 2024 (UTC)[reply]
