I spoke with several Roon guys, one of which had many years in the digital recording industry.
#GIGABIT ETHERNET OPTICAL ISOLATOR ISO#
Perhaps instead of complexity of optic media converters, would I not achieve added isolation and similar sonic benefits by introducing the new Uptone ISO REGEN after the MicroRendu? I continue to read I need to isolate my downstream NAS switching power supply noise, but the so called solutions recomplicate the whole mess with more D.C. One of the reasons I moved to the Synology NAS and MinimServer to the MicroRendu was simplicity and to ditch the computer completely out of my system.
I'm over boxed and over wired already with nine required outlet with digital only front end, preamp pwr amp and active sub. If I replaced the optic media converters power supplies with a linear and a Fiber network cable would this create the isolation I'm seeking? I'm under the impression that the cure can be worse than the illness. Are you saying I should avoid the fiber optic media converters because they introduce will two switching power supplies and a toslink cable? Who did you talk to from Roon, former AudioQuest computer audio person Steve Silberman? Many members of the CA community have done this and can recommend all the pieces you need. If you want, it can wrap around your block as well. Introducing two additional switching power supplies is troublesome.įiber network cable can wrap around you house a few times without any length issues. If you want to optically isolate your network, don't worry about anything related to optical toslink. The Roon guys said a $49 converter should be fine but see many variants and wonder what specs are adequate?Īny help on this topic would really be appreciated. With this arrangement I'm isolating the NAS noise and the sending optical converters noise but am I not introducing a new switching power supplie's noise with second converter after the optical isolation? Should I seek out a certain optical cable? Is there a certain desired max length for optical match up to the converter? With this concept in mind won't an optical link become the new weakest point? If I'm wrong, then why not use one long optical cable and two short Ethernet cables? One old audio adage is that if you loose detail or data on the beginning side you can't reclaim on the other side. I've alway found optical toslink or even glass links sound poor. Ok, so much of this makes sense, some of it does not.
I was told further to get several gigabit fiber optic media converters, one being the sender and the other being the receiver. They were firmly against the whole concept telling me"no, you need to optically isolate the electrical noise in your ethernet signal path ". I told them I was considering a passive in line device to reduce noise on my Ethernet cable signal coming from my Synology NAS. Contact factory for details.I've just returned from the Axpona show. May be used in conjunction with an POE Injector. NOTE: Product will not support POE (Power Over Ethernet). This filter automatically selects the fastest communication speed and can translate between 10/100 and Gigabit networks. They act like a hole in the shielded enclosure to all signals, good and bad, within the passband.ĮTS-Lindgrens GigaFoil v3 is designed for 10/100 Ethernet and Gigabit Ethernet networks. In order to avoid this side effect, it is necessary for standard signal line filters to have extended passbands that allow the higher frequencies to pass unimpeded.Īlso, it is important to note that standard ethernet signal line filters do not differentiate between Ethernet signals and undesirable signals. However, these types of filters often eliminate the high frequencies that make up the sharp edges of high-speed digital square wave signals, thereby degrading the integrity of the signal.
Standard signal line filters rely on capacitors and inductors to eliminate unwanted RF signals. Housed in a single filter package, these filters are the most convenient and reliable solution for bringing Ethernet access to all varieties of shielded rooms and enclosures.
ETS-Lindgren's GigaFOIL Ethernet Filters utilize patented technology and are the only EMI/RFI filters for Ethernet on the market that offer 100 dB performance from 10 kHz to 10 GHz and higher.
