Etherloop vs. EFM 2BASE-TL
editCan somebody knowledgeable write a few sentences about the difference between Etherloop and Ethernet in the First Mile's 2BASE-TL? They seem to me to be the same ?? 174.6.87.98 (talk) 02:45, 25 April 2010 (UTC)
- Hard to tell, since this article has no sources and not much detail. It might just be a neologism that never caught on, or one vendors' product name. Either way it might not be notable by today's standards. A quick US trademark search shows two: ETHERLOOP (all caps, but seems EtherLoop in the ads) was the one applied on September 28, 1998 by Elastic Networks, marked as still active. The other EtherLoop was filed May 7, 2007 but then abandoned less than a year later. Certainly a 1998 technology would not be "next generation" by today's standards. They are all "next generation" when they are first marketed, so that is just peacock wording. Elastic Networks seems to predate the IEEE work, but sometimes standards are based on products (even patented ones) and drop the trademark names or come up with new ones like Wi-Fi. Certainly it is a care of the generic concept of Ethernet in the first mile in the lower case sense, so I will propose a merge. W Nowicki (talk) 19:15, 15 August 2011 (UTC)
Also the user Special:Contributions/Dkovacs who created this one also created High Speed Voice and Data Link without any sources except a commercial link, and then has been inactive for four years. Also it looks like Zhone Technologies now is the vendor, and I see a service advertised from ForeThought.net it says since 2008, but no idea if this service uses the technology with the same name.

Telsa Cybertruck
editApparently is using etherloop instead of CAN. Noteworthy? 152.117.104.209 (talk) 20:56, 11 December 2023 (UTC)
- Yes, absolutely, 152.117.104.209. I'm working on improving the article to just do a decent job of what EtherLoop is, how & why it came about, and what were its initial applications. When that gets a bit farther along, I def plan to enhance the article with the application of EtherLoop in short-distance motor vehicle applications, of which I believe Cybertruck is the first.

- About 2010 I was writing software for ticketing systems where the ticket processors on the bus/train were connected together via ethernet (for VT and SL in Sweden). Not exactly the same thing as Etherloop and it didn't control anything not related to the ticket processors but something to be aware of. Stepho talk 00:30, 28 December 2023 (UTC)
Done I wrote an initial stub section on the application of this technology to intra-vehicle communication for control & feedback in the recently-entered-production Tesla Cybertruck, and endeavored to capture a good cross section of the claimed benefits. N2e (talk) 19:36, 28 December 2023 (UTC)
Is there actually any evidence that the technology being used in the Cybertruck shares anything but a name with the technology the rest of the article is about? Etherloop in the telco sense in a point-to-point layer 1 + layer 2 protocol for connecting subscribers to central offices by means of transmitting ethernet frames over a pair of traditional phone cables. The "loop" is the local loop in the phone system/telco sense. Not a loop from a network topology perspective, and a single loop from a wiring topology perspective. There is no collisions detection or time division because there's no one to share slices with or collide with, and it's half-duplex
EtherLoop in the Tesla sense is apparently a means by which multiple gigabit ethernet speakers can be placed onto a 2-wire, redundant pair of loops and all communicate amongst eachother. I struggle to understand what it shares with Etherloop other than name and that it uses 2 wires as a connection point. They share nothing else.
Feels like this should be its own article. 2601:1C2:4501:CE70:E915:CA14:DAAE:A691 (talk) 04:03, 29 July 2025 (UTC)
- My understanding (possibly wrong) is that the Cybertruck uses Ethernet frames but uses CAN transceivers over a differential pair of wires. Also remember that Ethernet was original used as a multidrop bus protocol on a shared cable - see 10BASE5 and 10BASE2. Stepho talk 08:08, 29 July 2025 (UTC)
