The "B" side of the EtherREGEN operates at only 100mbps, and the new OM can accommodate that rate, whereas the original OM will not because it only operates at the gigabit rate. While indeed, copper connection of the opticalModule Deluxe to the EtherREGEN's 100Mbps port now becomes possible, that is not at all the reason for the creation of the opticalModule Deluxe. UpTone generally advises against putting anything between the EtherREGEN and whatever is the DAC-attached computer/streamer/render endpoint (or Ethernet-Input equipped DAC). Remember, the 'B' side of the EtherREGEN is a completely isolated power/clock/data domain. Introducing an opticalModule downstream also introduces another power supply, and the clock in Sonore opticalModules is the same Crystek CCHD-575 as used in the EtherREGEN, so no advantage there. No, the reasons for the creation of the opticalModule Deluxe where: a) Having the copper port able to negotiate down to 100Mps (the smaller original was Gigabit-only) allows people to us the oM Deluxe as an FMC facing to those streamer/renderer endpoints which are only 100Mbps. There are many of that sort. The original opticalModule was created as a means to turn copper network feed to fiber to input to their opticalRendu. But given that the oM is likely the best ("sounding") small fiber media converter on the planet, some people desire to use it to convert a fiber feed into copper for their streamers. This new version allows for that. b) Having added a small Ethernet switch chip in the oM Deluxe provides support for flow-control pause packets, bringing better compatibility with HQ Player NAA. Beyond that there are no technical performance advantages that I am aware of. (And obviously I have an inside line on such, given that John Swenson and I are on the phone at least 6 hours every week. ) I am not sure why Sonore has not been more clear about their new piece.. Guess they just have a different style of communicating about their products. Hope the above is helpful. --Alex C. kennyb123, R1200CL, TwinPeak and 2 others 3 1 1 UpTone Audio LLC Link to comment

Or does every device that touches the packets all the way to the server running HQP have to understand Flow-Control Pause packets? The EtherREGEN has always supported flow-control/pause-packets.

Actually they are the same interface and pinouts. 3 hours ago, agillis said: The opticalModule wouldn't even know how to "talk" to the module. It will just fine. As long as the switch at the other end is also a 1GB SFP port then two SFP+ modules will work fine. The modules have no clock and don't know of protocols, etc. It is all up to the Ethernet PHY/processor in the equipment itself. The modules are dumb. John will post elsewhere to clear all this up. He is using SFP+ modules for connection between EtherREGEN and opticalRendu. R1200CL, Markus8 and MarkusBarkus 1 2 UpTone Audio LLC Link to comment
Popular Post Superdad Posted March 18, 2021 Popular Post Share Posted March 18, 2021 1 hour ago, R1200CL said: Only SFP+ modules that also supports 1GB will work. Simple as that. No, not simple as that! SFP/SFP+ optical transceivers do not have clocks, do not negotiate data rates, do care about data rates or even protocols. SFP+ optical transceivers are capable of 10Gbe--or 6.789467xx or whatever--it is all set by the driving circuitry in the gear at each end. So ALL SFP+ transceivers can also run at 1Gbe. John will explain more. 1 hour ago, R1200CL said: The data sheets for SPF+ modules specifies supported data rates. No, they specify maximum rates supported. As mentioned, one could design a circuit to plug an SFP transceiver into and transfer any sort of LVDS date at any unique and bizarre rate--as long as you are doing the same at both ends. 1 hour ago, R1200CL said: If that PHY really supports 10 GB transfer rate by SFP+, just say so. We would have said so if it did. The EtherREGEN uses a 7-port Gigabit switch chip with integrated PHYs. 10/100/1000 Mbps only. No 10Gbe! 1 hour ago, R1200CL said: Looking forward to John’s post. He is typing it now. I know it is hard, but please be patient. It will be in reply to you in one of the other there or four threads where you are excitedly postulating. ambre and R1200CL 1 1 UpTone Audio LLC Link to comment
Superdad Posted March 18, 2021 Share Posted March 18, 2021 4 minutes ago, R1200CL said: This indicates that a (two) 10GB specified SFP+ module actually will or can work in a SFP port. No matter what articles on the net says. So @AfterDark. plan of making a compatibility list is probably the only way to go. "Compatibility list" is really not necessary. All you need to do--if you wish to use a pair of SFP+ fiber optic transceivers in a device whose SFP port is 1Gbe-only (such as EtherREGEN, opticalModule, opticalRendu, etc.)--is to be certain that the cage at the OTHER end (switch typically) is also a 1GBe-only SFP port and is NOT a device that supports 10GBe (so-called "SFP+ port"). The connections are all electrically the same between SFP and SFP+. And the transceiver modules themselves do not negotiate anything. It is all about the devices you plug them into! ambre 1 UpTone Audio LLC Link to comment

Superdad Posted March 18, 2021 Share Posted March 18, 2021 4 minutes ago, The Computer Audiophile said: There must be something in the SFP+ telling the switch that it handles 10Gb, else the switch would just try to send 10Gb in a 1Gb SFP. Nope. Please refer to John's full explanation here: UpTone Audio LLC Link to comment
Superdad Posted October 30, 2021 Share Posted October 30, 2021 1 hour ago, R1200CL said: (Not sure if 50 ohm version is available). Both 50-Ohm and 75-Ohm clock input versions of EtherREGEN are sold out until end of January 2022 (darn global chip shortage!). About 10% of each 250 unit production run are built as 50-Ohm and available on special request. But when using a sine wave output 10MHz reference clock impedance matching does not matter at all. It is only relevant when using a square wave clock. 1 hour ago, R1200CL said: … also the EtherRegen comes with a 30 day money back that to my knowledge only one person has ever used. Out of soon 2000 sold. Actually about 8 people out of 2,900 have returned. That’s okay, tastes will vary… kennyb123 1 UpTone Audio LLC Link to comment
Superdad Posted October 31, 2021 Share Posted October 31, 2021 4 hours ago, zoltan said: - If impedance matching doesn't matter (REF 10 is generating a sine wave) then I could practically use any cable also? So it doesn't even have to be either 50 or 75 Ohms? Actually, the excellent Mutec REF10 is one of the few clocks out there that is a square wave output. So for you impedance matching and a cable with very wide bandwidth is important to preserving the shape of that. Fortunately your REF10 offers both 50-Ohm and 75-Ohm outputs. Please refer to our paper linked here: 4 hours ago, zoltan said: - For now, I already have a streamer, a USB reclocker and two Mutec MC3+USB reclockers connected to the REF 10, the ER will be the fifth device. Should they be connected with the same cables and same lengths to work in sync or it makes no difference if cables are different? Should not matter if the clock cables are same or different, but since your clock is square wave and two of its outputs are 50-Ohm and six are 75-Ohm, you’ll need to pay attention to that and use cables that match those outputs. Again, see the linked paper with regards what matters in a clock cable for square wave (quite different than what matters for sine wave clocks). 4 hours ago, zoltan said: Bonus question: I possibly use my JS-2 to power the ER. Will sound better/run cooler at 9V or 12V, or makes no difference? Due to the design of the EtherREGEN’s power networks, neither heat nor sonics will vary with input voltage. Wattage consumed is the same, so current draw is lower at 12V (0.8A) than at 9V (1.0A) or 7V (about 1.35A). zoltan 1 UpTone Audio LLC Link to comment
Superdad Posted November 2, 2021 Share Posted November 2, 2021 1 hour ago, zoltan said: I should sell that and just get another JS-2. The problem is that I live in SE Asia now and shipping a JS-2 here reliably is quite expensive I guess. Door-to-door FedEx Express shipping of a JS-2 in its 7Kg double-boxed carton to any location outside of North America is the same $95 we have always charged. (arrangement regarding lowered customs value declaration is discussed privately). Presently accepting reservations for the next build batch, begun today, for shipment by November 23rd. Contact me via e-mail or our web site if you indeed wish to obtain another lovely JS-2. UpTone Audio LLC Link to comment

Superdad Posted December 5, 2021 Share Posted December 5, 2021 2 hours ago, Mihaylov said: Some users of the optical module have problems when powering the optical module from LPS-1.2, No, it is the opticalRendu that exceeds the 1.1A capacity of our UltraCap LPS-1.2. The opticalModule (even the Deluxe) is fine with the LPS-1.2’s 1.14A limit. muski 1 UpTone Audio LLC Link to comment

Superdad Posted October 18, 2022 Share Posted October 18, 2022 2 hours ago, muski said: I'm powering my new OMD with an LPS-1.2 @ 7v. Both the LPS and the OMD are running a little warm (but not hot). Do you think I could I set the LPS to 5v? 5V will probably be fine as well. It won’t change the thermal dissipation of the UltraCap LPS1-1.2 since the opticalModule will be drawing about the same current. But a lesser voltage drop across the opticalModule’s LT3045 linear regulators could result in slightly less heat from it. (I can’t recall if the new version has DC-DC pre-regs fronting the LT3045s; depending upon if it does—on some or all the LDOs—a lower input voltage to the unit might not make much if any thermal change.) Honestly I would not sweat it. muski 1 UpTone Audio LLC Link to comment

Can I use the same 5v power supply with the OM Deluxe or do I need a higher voltage power supply? 5V is fine for the opticalModule Deluxe. UpTone Audio LLC Link to comment
