Popular Post charlesphoto Posted September 5, 2020 Popular Post Share Posted September 5, 2020 So I recently upgrade to an opticalModule to opticalRendu system, replacing the oM to oM bridge to microrendu I had before. I set aside the spare oM to sale. Well, on a whim, I decided to go from an optical fiber out on the main Cisco 2960 switch to an oM, then ethernet cable to the second oM, and then fiber of course to the opticalRendu, thereby creating two optical bridges between the switch and the opticalRendu. So, Cisco 2960>MultiMode fiber >oM (LPS 1.2)>Ghent Catsnake JJSG RJ45> oM (Uptone 7.5V charger)>SingleMode fiber > opticalrendu (Sonore PS)>USB>Naim DAC V1. The other SFP output on the Cisco goes to a 10Gtek FMC (5v iFi) in the office and the Naim Unitiqute. And it's no longer for sale! Very detailed, wonderful sound with the addition of the second opticalModule. Took care of some bass bloom and it's obviously really cutting me off from the noisy switch. I'm assuming I might reach the same place with a single etherRergen (though it wouldn't be a full double optical bridge, but one less device). I wouldn't know as they're all sold out for a few months; would love to demo one. Lots of stuff to plug in though, and with the circuit already loaded with the home photography office, etc. the addition of a couple of iFi AC iPurifiers really made a huge difference as well. It all looks crazy though, more so probably on camera and paper than in person. The AC Infinity USB fans help keep everything running cool - easily powered from the NUC in the closet and on low almost completely silent and vibrationless. The one next to the opticalRendu is powered via wallwart (different circuit). Lots of Herbie's Audio Lab sprinkled about as well - baby booties and superstabilzers on the Sonore oR and PS, and cut pieces of dbNeutralizer pretty much everywhere else. Sounding really sweet, and pushing the Naim DAC V1 output as far as I can. Garbage in, garbage out, all down the chain, I'm finding.

Frojo Posted September 17, 2020 Share Posted September 17, 2020 Hi Charlesphoto, Please may i applaud your efforts in 'exploring the boundaries', at least in my terms! I too would like to follow your lead in a limited way and cascade a Cisco 2960 (8 port) into my etheRegen via SFP. Please could you advise which Modules you are using for your cisco? I am looking for a budget pair to experiment with , LC multimode probably. Link to comment

I am looking for a budget pair to experiment with , LC multimode probably. Out of the Cisco I'm using OEM multimode GLC-SX-MM SFP's that I picked up for about $5 on eBay. For the final opticalModule to opticalRendu I'm using single mode SFP's from Finisair, refurbished for about $25/ea. For the Cisco though, the most important thing is that they be Cisco coded, whether OEM or generic third party.
