The new Sonore opticalModule Deluxe

Flow control, I don't think the orig handled that spec eloquently or maybe not at all

I agree. Its not handled eloquently, nor is it informative. Its not at all clear to me why one would purchase this as opposed to the original OM, other than it has the RJ45 port and SFP cage on the same side of the device. What I would to know is if the new ultlralow noise voltage regulators, or crystal oscillator are higher specification that in the original OpticalModule, or not. And if so, which ones are used? 

 

Also, what does "supports flow control" mean, exactly?

 

So, my question is, why would I decide to buy this as opposed to the original OM? 

 

It's not clear from the web page or specifications.

One reason might be compatibility with an EtherREGEN - i.e., using the EtherREGEN with an external OM rather than the internal optical cage of the EtherREGEN. 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.

 

EDITED to note that @ericuco already saw this use case and explained it better, too!

Hi JIm, thanks for your reply. It actually it works fine for an optical setup because the the optical connection on A-side of ERe operates at the gigabit rate. So, you can have the ER upstream (in through B-side, out through A-side SFP, and on down to the OM SFP Gigabit downstream, connected via fiber, and everything works fine (I've done this).

 

But I think what you're saying is that if you went out of B-side of ER to the RJ45 copper Ethernet port on the original OM (so that you could go out via optical fiber, to say, an OpticalRendu, it wouldn't work because of the RJ45 port mismatch between B-side ER (100 megabytes) vs  the RJ45 port on OM (Gigabit). I think I've got that right....😜 😀 Please correct me if I'm wrong. Cheers.

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.

Alex, thanks very much for providing this important clarification.

 

Jim, just so that I am perfectly clear, when I stated above that "everything works fine", I meant that from a strictly functional perspective, i.e., this set-up would function. Alex is 100% correct that the optimal configuration for best possible audio quality is to have OM upstream at the "network end" and ER downstream, at the network bridge or optical "endpoint" and on to the DAC. in particular, to take full advantage the  completely isolated power/clock/data domain on ER 'B' side. And, this how I have my OM/ER system set up (see my system description below in the footer). Cheers.
