  1. I might be one of those cynical over there (I own a etherREGEN) but I still wonder how you @Superdad thinks about the CE marking of a product that you sell to stores within the EU. https://ec.europa.eu/growth/single-market/ce-marking/manufacturers_en "Manufacturers play a crucial role in ensuring that products placed on the extended single market of the European Economic Area (EEA) are safe. They are responsible for checking that their products meet EU safety, health, and environmental protection requirements. It is the manufacturer’s responsibility to carry out the conformity assessment, set up the technical file, issue the EU declaration of conformity, and affix the CE marking to a product. Only then can this product be traded on the EEA market.I f you are a manufacturer, you have to follow these 6 steps to affix a CE marking to your product: Identify the applicable directive(s) and harmonised standards Verify product specific requirements Identify whether an independent conformity assessment (by a notified body) is necessary Test the product and check its conformity Draw up and keep available the required technical documentation Affix the CE marking and draw up the EU Declaration of Conformity (27 KB). These 6 steps may differ by product as the conformity assessment procedure varies. Manufacturers must not affix CE marking to products that don’t fall under the scope of one of the directives providing for its affixing."
  2. The power will be the same as P=U*I and it draws almost the same at 7 and 12V think it was around 7-7.2W no matter what voltage I used and the temperatur was that same regardless of voltage.
  3. If you use 1m, 10m or a 100m with a SFP designed for 80km will not make much diffrence in the power that the recieving end will see. You might have something like 0,2-0,5dB/km in attenuation on a single mode fiber. In the long run you might burn out the reciever end but it might work fine it depends on what SFP you use. https://www.fiberoptics4sale.com/blogs/archive-posts/95048006-optical-fiber-loss-and-attenuation Damage by Overpowered Transmitters? Well, yes and no. Actually, most optics transmit at roughly the same power. The typical outputs of 10km and 80km optics are within 3dB. Long reach optics achieve their distances by having more sensitive receivers, not by having stronger transmitters. 80km optics may have a 10dB+ more sensitive receiver than 10km These sensitive receivers are what are in danger of burning out. There are two thresholds you need to be concerned with. Saturation point (where the receiver is “blinded”, and takes errors). Damage point (where the receiver is actually damaged). The actual values depend on the specific optic. But generally speaking, only 80km+ optics are at risk. https://serverfault.com/questions/731068/can-fiber-optic-cables-be-too-short-dbm-too-high
  4. @Ricardo007 I have a Ubiquiti EdgeRouter X SFP. Yes you have to configure the sfp to be a regular LAN port (ETH0 WAN, ETH1-5 LAN and 5 being the SFP. I have not compared to copper.
  5. @Ricardo007 I use this from Corning they are considered to be really good quality.
  6. That might be correct as they work in my Ubiquiti router and the etherREGEN. "FS generic compatible transceivers break free of vendor lock-in and guarrantee continued flawless interoperability and compatibility with third party vendors."
  7. I use these from FS.com, zero problems and the fit is really good. Single-mode 1310nm modules and cable are from Corning.
  8. If they are that short you could never connect them. I would say they are around 30cm or one feet.
  9. I often use this album and the song Magnetic lies when I test stuff in my system. I cant say that the bass has changed with the new firmware in my case.
  10. I think I will to be safe just tie the shield at my endpoint even if I dont have any external clock and LPSU in the endpoint. Great post by the way. @JohnSwenson 👍
  11. Just so I got this right. If you dont use any clock connection it does not matter if the LAN cable on the B-side have the shield connected at the eR side as the connection ends via a capacitor to the groundplane on the B-side? But if you use a clock connection you might form a ground loop or even disable the whole isolation if the clock is powered from something that also connects to the A-side?
  12. This is not what I did I checked between BNC shell and the shell on the RJ45 on B-side they are supposed to have the same potential or did I get that wrong?
  13. You might consider that a STP cable with shields tied at both ends will on the eR B-side act as a cable with the shield just tied on the destination (the RJ45 outershell on the eR B-side have no connection to anything else besides the ground on the bnc connector). @Superdad I know you wrote that the shell on the RJ45 on B-side only have connection with bnc ground but when I checked it with my multimeter there was no connection.
  14. I run Roon 1.7 and Qobuz with zero problems, seems that the problems with 1.7 only affects some setups. Played several hours last night with my eR connected no issues.
