Optical Conversion Not Working, Please Help

What is it that you are trying to do?

Are the Finisar SFPs compatible with the 10Gtek FMCs? Looks like 10Gtek is Cisco compatible. Finisar isn't compatible with Cisco, though, so that may be the issue. I don't think 10Gtek is compatible with both Cisco and Finisar. 

Thanks toro. Do you know of a pair of converters that would be compatible with the Finisar cable and modules? 

Someone with more knowledge will hopefully provide a suggestion in regards to the FMCs. Ironically, I did a deep dive on optical last night. I found threads from WhatsBestForum (here, here, and here) pretty helpful, as well as some from Audiophile Style.

I think the question I have as a follow-up for the community is whether or not that "active" optical cable may also be causing an issue - I candidly don’t know, but I vaguely remember reading this as an issue in one of the threads above.

Like you, I’m still learning while regurgitating some of the information I had been reading last night. I'm pretty confident more members will contribute to help figure this out. As a side note, I've found one of the easier paths is looking at Small Green Computer's solutions, which can be found here and here. 

I would have stuck with something simpler, that has the media converter built in. Keep in mind that 100 MBits is overkill for any streaming of audio or video. 1 Gbit (1000 Mbits) is overkill x 10.

A 192k/24 bit stereo signal is barley 10 Mbits.  A 4K video stream requires around 50 Mbits or less, depending.

So, a 1 Gbit/s cable can carry 20 4k video streams at once.

Maybe that can help you pick out a better integrated adapter and cable such as:

Try a different Toslink cable. The one I got from Blue Jeans does not work in half of devices I've tried.

Make sure that the you are using the proper optical cable. Then make sure you are suing the proper and identical SFP modules compatible with that cable on both ends of the cable. Then reboot your network so your router sees these connections and assigns the proper IP addresses.

Take a look at what these guys sell. Not too expensive and it works great. I have a few OpticalRendu's using their accessories.

@brylandgoodman This is what I use for my two systems and it works great.  Lps is optional but better than wall warts.  Small green computers is excellent but more expensive if that matters.  I own their sonic transporter it is fantastic.

I can't really figure out what he is trying to do... not sure why he isn't plugging the ethernet cable into the modem and the modem into the computer. There are multiple programs you can work with directly on your computer once they get there that should do whatever it is he wants to do and unless I missed something, a lot simpler.

Back up first and be sure everything works in copper. Any old dirt cheap CAT-5 cable will do.  Actually it will do as well as any snake oil "audio Ethernet" cable.  Ethernet and TCP guarantee every bit is right. Everything is buffered so no magic timing differences.  

Then test/listen to the system and see if you have a problem in the first place before you add band-aids for problem that does not exist or think you can magically get sonic improvements. You won't within the laws of physics in this universe.  I know, some here seem to be in another universe with different laws where the IP stack is analog. 

Optical transceivers should be totally transparent to the computer/router/switch etc ports.  They just convert bits to bits and do nothing to the protocol, unless newer venders have found ways to screw things up.  The transceivers we used were st connections for multimode fiber and did 1G E. I can't remember the brand but they were cheap and reliable. Grey box.  Multimode and single mode fiber are not interchangeable. 

I do not understand why an "active" optical cable and also list transceivers. You  should just need an SPF cable. 

@tvrgeek Why do folks do this? You are confusing the OP even more with your, yadda, yadda, yadda. He asked for an answer of a specific question he did not ask for a dissertation on Internet Protocols and Data Packs. 

If you do not have an answer put a sock in it.  Start call you fredrik222 junior.

OP your Finisar transceiver is the issue as it is 10G,  the 10Gtek is not 10G compatible (has nothing to do with Cisco or Finisar.) You need to get a 10G compatible Media Converter Bridge to use this transceivers you purchased.     

Jeff, 

Because the OP is confused by not understanding what he is trying to do. No need to call people names.  Maybe you can proceed without any knowledge, but I find a little bit helps. 

Fact is you did not know the answers, I have the knowledge.

Some folks just enjoy being disruptive. It's as when a guy asks for a phono cartridge recommendation, and a user tells him to get a streamer instead. Or the guy here who recently asked for DAC advice, and was told to buy a 4K TV and an "object based" sound system instead.

Why buy a DAC that can only do channel based audio in 2023? It is like buying buggy whips in 1920 when the car was replacing horse drawn carriages.

People said the same crap back in the day of Quadraphonic Audio, Atmos will pass just like your lunch will. @kota1 is so boring and predictable, like a few others here fredrik222 and jasonborne666.

@jeffrey125

Dolby Atmos is a digital standard for both audio and video that works on all platforms and is backward compatible. Why would I want to BUY multiple sources, dacs, and preamps today that will be boat anchors within five years? Buy one box and a firestick and you are done, keep the change thank you very much.

OP, did you get the right cable? This is the one that goes with that unit:

@kota1  - "Why would I want to BUY multiple sources, dacs, and preamps today that will be boat anchors within five years?"

What hi-end manufacturers  are you seeing divorcing themselves from 2 channel audio that this is going to be the case?  

OP:  The experts are on audiophilestyle.com, if you still need help.

Logical fallacy, circular reasoning, aka "begging the question."
