For a domestic installation, basic multimode cable and $10 10Gtek 1gb transceivers is all you will ever need.
Single mode is only.required for distances over 550m.

Sonore Optical Module Deluxe and the ER combination are fantastic, looking forward to the ER v2. The LHY was on par with other Asian FMC I had tried that cost 1/2 of the LHY. I also run 2 different Finisar SFP based on a recommendation by a friend on anther forum, made huge improvement. He made the recommendation as we have similar networks. He has a similar opinion for LHY. I am glad it works for you. Cheers and Merry Christmas.

Which FInisar SFP did you use? I've never been able to make SFP work with my EtherRegen. Unclear why.

Actually not. But you can use the cheap retail stuff the Finisar have better isolation as they are designed for industrial applications. You do you.

I agree, but what I need and what I want are different. I started with basic devices, and gradually upgraded to audiophile gear for better sound quality.

I use basic 1G and 10G transceivers in my secondary systems, but I only use FTLX1475D3BTL and FTLF1318P3BTL in the network feeding my main system. Finisar BTL transceivers are laser-based vs. LEDs used in cheaper modules, and are quieter. Also, Finisar actually manufactures their modules. 10GTek purchases and rebrands from third-party suppliers.

Single-mode fiber is heavily preferred and recommended by audiophiles for best sound, possibly because multimode allows internal reflections between strands, single-mode only uses one strand.

My audiophile fiber media converters (Sonore oMD and Uptone ER) are designed for sound quality, and definitely sound better than my generic FMCs (TP-Link MC220L and 10GTek 1G). Linear power further elevates the sound.

That's odd. As far as I know the EtherRegen is non-specific, should work with any module that supports 1G. A common error is mixing 10G transmission with 1G reception. That will not work. Which SFP have you tried? What does your network looks like?

This is not a retail product. SFP transceivers are designed for industrial applications, the world's global telecoms networks.

Finisar, 10GTek and many others make millions of these things for the global telecoms industry. Given the demand for these products it is hardly surprising these are made in vast quantities in the Far East that are just as good and cheaper than USA based companies.

These products work on different wavelengths. Standard 1G stuff is 850nm. 10G uses longer wavelengths. Mixing components is a bit like trying to use a bayonet lightbulb in a screw fitting.

That is not correct. All of my transceivers, 1G, 10G and dual rate 1G/10G, are 1310nm wavelength. All of them work in both SFP and SFP+ ports, but if I use 10G upstream from 1G there will be no communication, because a 1G module cannot read a 10G data stream.

Good that you brought up wavelength though, because the transceivers do need to be on the same wavelength. You also need to match the fiber cable with the mode, and the connectors to the SFP (LC type, blue connectors with yellow cable recommended).

FTLX1475D3BTL in the oMD and FTLF1318P3BTL in the ER.

I switched them around (pun intended), and like the sound of 1318 in my ER. Thanks for the tip.

 

[audiobomber]

I feel bad about all the fiber talk in a thread that is supposed to be about Network Filters. Maybe a mod could move the off-topic posts to a new thread?

There's an older thread here that I had forgotten about:

Fiber vs. Ethernet sonic differences

Hi Everyone, This is my first post. I was stunned to hear difference between my DAC connected via laptop, then a raspberry pi based streamer on LPS, then a cheap cat5 and finally a decent cat8 cable. After recently realizing that inputs can make significant differences, I have been going down...

You only need 10G if you're building a data centre, and that's from a guy I know who builds data centres.

1G is fine for most commercial buildings and businesses. For domestic use 10G is complete overkill.

Audiophiles prefer lots of things that make no sense at all, worrying about single mode or multi mode when using stupidly short lengths of fibre (25m in my case) is just completely nonsensical.

I'm sure there's an audiophile or two out there who thinks a different brand of transceiver gives greater soundstage and lower bass - we're talking encoded data travelling in 850nm light waves. You don't have to think about it for long.
Rather than linear power (sometimes rather over-rated), I use a 9v battery unit for my FMC. It has two batteries, one provides power, the other charges when necessary.

You can do 10G at 850nm over short distances, but data centres and telecoms systems will be running at different specifications than local networks, longer frequency, higher data rates and laser based given cables can be up to 10km.

If you’re putting in a domestic fibre LAN, as I did 10 years ago, standard 1g multi mode with LED transceivers is all anyone will ever need. Nor will you ever need more than CAT6a.

I have a fairly large local network (in fact two networks) with up to 90 active devices of which 25 are audio systems capable of operating at 24/192 PCM at the same time WIRELESS. The AV and main hi-fi are supplied over fibre-optic cable, everything else over wired access points with meshing switched off. It was supplied by the largest company in the small and medium business sector in the UK. They have an annual turnover of about $80 million. They manage my system externally. I could try and manage it myself using Container Station on my QNAP, it’s just easier to let them do it. They have a lot of network engineers and the ones I’ve spoken to over the years have advised me that there is zero benefit in over specifying a domestic or small business network.

I first worked in global electronic data switching in 1981. It was very new. For my sins, I was programming Tandem dual processing systems. Some years later I found myself advising them on various acquisitions, I remember one in New York and a couple in Switzerland. The equipment was expensive and in the 1990s when interest rates were high, my father had a business leasing telecoms equipment and other hardware (I remember Prime systems, which cost an absolute fortune). But as far as the hardware we use in domestic and small business systems, it was just solved technology decades ago and I just don’t understand why anyone gets in the least bit excited about it.

When I first went to China and India in the 1980s, they were Third World countries. I remember going to Guangzhou in 1984, they proudly announced they’d installed their first traffic light. Is it now the centre of the largest export zone in the world. they are now so advanced and so less dependent upon the US and other western economies, it really does seem strange to think that they should remain tied to the US dollar.

1G is fine for most commercial buildings and businesses. For domestic use 10G is complete overkill.

I agree, except that a very network savvy poster called jabbr, over at The Computer Audiophile website, said that 10G has far lower jitter than 1G. Some people who tried 10G thought it an improvement. When I set up my computer build, it made sense to go with 10G fiber because the difference in cost was minimal vs. 1G fiber.

I am not able to say how 10G impacted the sound, because there were other changes implemented at the same time, but I can say that my desktop system sounds the best it ever has.

I purchased the MikroTik CRS305 shown in jabbr's post below to link with the Intel X710 I0G SFP+ port in my computer. The CRS305 was active as a switch while listening to Qobuz in my main audio system. It was not good with the supplied wall wart, quite a bit better with a cheap Zero-Zone supply and very good powered by a Teddy Pardo 12/2. Unfortunately, not good enough to replace my opticalModule Deluxe v2.

Audiophiles prefer lots of things that make no sense at all, worrying about single mode or multi mode when using stupidly short lengths of fibre (25m in my case) is just completely nonsensical.

It's about sound quality for audiophiles, not distance.

I'm sure there's an audiophile or two out there who thinks a different brand of transceiver gives greater soundstage and lower bass - we're talking encoded data travelling in 850nm light waves. You don't have to think about it for long.

I hear opinions from audiophiles, and from audiophile media daily. I try things when it's feasible to do so. I have four different transceivers in-house and can easily hear the differences. A big difference between you and me is that I listen in my own system before I form an opinion.

Rather than linear power (sometimes rather over-rated), I use a 9v battery unit for my FMC. It has two batteries, one provides power, the other charges when necessary.

Batteries have their own problems, seriously compromised without regulation, and low noise regulators are not easy or cheap to design.

From Alpha Audio:
"Who thought a battery works better: nope…. the bump at 100 Hz is higher and eventually also at 1Hz the noise is highest. Almost 10dB higher than the standard power supply which oddly enough scores best there. On average, the Sbooster power supply seems to score best: it has no real outliers. The lab power supply has some bumps between 10 and 1 Hz."

About power supplies for switches - does it really matter now?

This is what happens when we let a 25MHz VCXO clock the Dlink switch. There is actully quite a bit of noise added!

www.alpha-audio.net

Barrows designs power supplies for Sonore:

"Batteries basically suck. I have experimented with many battery based solutions, both post regulated/filtered and not, and all the battery based systems I have tried have not ever equalled a really good linear power supply (or even a really good SMPS with post filtering/regulation).

Batteries are also a PIA, bad for the environment in the long term, and they change their performance (noise, output impedance and voltage) with the level of charge present. While it is possible to make batteries work well, to do so requires so much extra circuitry, that one might as well have just made a really good linear power supply instead."
