Unfortunately not all SFPs work with all switches/converters. You should adhere to the recommended list of SFPs of the switch manufacturers. Cisco's typically require the SFP (Eprom) to be programmed so that the switch reads it. There is a huge thread in CA about SFPs.
Stack Audio-SmoothLAN Network Filter- WOW!
I just received this item that I purchased from Stack Audio after being impressed with the AUVA 100 Speaker footers.
For any of the Audio Streamers out there, my initial comment as to this item: The SmoothLAN Network Filter is WOW!
From first plug in, the soundstage deepened and widened immensely. How the heck this occurs is nothing short of amazing. I have tried many of the major brand ethernet filters, and some of them, maybe, did something. But not enough to keep them. I either sent them back or sold them. I did however keep an iFi Silencer unit.
My digital streaming consists of an EtherRegen sending out the signal via Fiber to my Lumin X1. I have the Stack Audio device going into the EtherRegen from the Modem.
And, since I have my Apple TV coming out of the EtherRegen it will be interesting to see if the Video improves.
Check out the review in EAR.

@maxwave There is a lot of confusion between SFP and SFP+. For audio there is absolutely no need for SFP+, the only thing that SFP+ MAY help is the extremely tight jitter specification of the protocol. There is no conclusion that SFP+ is better than SFP (for audio). To make things more complicated there are some SFP+ modules that will work at dual rate and could be compatible with a SFP module at the other end. Lumin and most other audio companies do not support SFP+ and in fact as you found out most of them support only 100MB data rates. You have done the right thing and asked the supplier about compatibility and anyone who does not want to risk fiber optic issues should read the manual or if possible contact the manufacturer. |
@jimboman James, yes the Finisar modules seem to be one of the most popular. Get LC modules perhaps something like FTLF1318P3BTL or if you like to try AOC (Active Optical Cable) then the Cisco SFP-10G-AOC5M or similar, but please do check compatibility at both ends. |
Sorry for the late reply. The thread that @bill_k mentioned is the correct one. It is a good one but it can be confusing as there are conflicting information sometimes. There is also a spin off thread on the same site about DACs (not D/A converters but Direct Attached Cable) which is related on the same subject but I would recommend one step at a time... If you need any advice let me know ( I am by means an expert, I just got some basic knowledge with SFPs). |
@jimboman Perhaps an Etherregen or an Sonore optical Module? How are you connected to the Cisco 2960? What is your network structure? |
@ozzy Have a look at the following two threads, the first one is massive and has been going on for years https://audiophilestyle.com/forums/topic/24002-optical-network-configurations/page/143/#comments https://audiophilestyle.com/forums/topic/69926-direct-attach-cable-thread/page/11/#comment-1286369 |
