Ahhhhhh....maybe this could be the problem.
Can you resend the link to the Cisco 10km 1310nm again? Many thanks
I bought the 2km distance cos I thought 10km was overkill lol

The X1 has been on for the last 5 minutes and Network Error is still being displayed

It is something odd - it is meant to be used with multimode fiber, not the single mode fiber you purchased. I believe it is a mismatch in your setup.

We did test the more common $7 Cisco 10km 1310nm 1000BASE-LX variant which is actually cheaper despite the longer distance:

You may consider buying two pairs of these, since it's not expensive anyway.

What transceiver type should I select - SFP-GE-L?

OK...ordered 4 pieces and keeping fingers crossed
Thank you again, Peter

These are the ones I use for QNAP NAS to the QNAP switch: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

These are the ones I use for the switch to the X1: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Certainly not the cheapest but they worked.

The CISCO switch arrived and I replaced the TP-Link switch.
The X1 was able to detect the network and all is working fine now

However, the NAS is still a problem.

Excellent news on the X1! What's up with the NAS?

The NAS still cannot be detected with SFP connection. Copper is ok

So can you see the SFP interface as one of the two or three interfaces in the QNAP configuration page? If you can see it, can you then assign a static I.P. to the SFP module? You said QNAP was remoting into your NAS or is that something coming up later?

They have checked and confirmed settings to be all ok.
They are asking me if they could test setting up virtual switch

Let me how how I can assign a static ip to the Adapter 3 on the NAS

Control Panel -----> Network and Virtual Switch ----> Go to the three vertical dots to the right of the adapter ------> Configure -----> Setup IPV4 ----> mine is 192.168.1.xx (set yours to something you can remember), subnet mask 255.255.255.255 (/24) and the gateway is the address of your router (192.168.1.1 in my case). Jumbo Frame is 1500.

If you can do that then I guess disconnect the copper and reconnect and try fiber.

Thank. I will try later

Tried but Qfinder Pro still could not detect the NAS..... Very likely I bought the wrong SFP module (SMF/MMF GE-S-2) instead of the GE-L module

Fiber cable is SMF:

CISCO switch is using SFP and my NAS is a SFP+ port. Anyway, to handshake these 2 devices with the right SFP modules?

Happy that my X1 is playing beautifully via fiber now....was out of action for the past week

After listening to the X1 on fiber for a couple of days, my 1st impressions are:
1. More treble extensions
2. Lack of bass extensions (more highs than lows)
3. when played at louder volumes, overall SQ is cleaner but sharper
4. SQ is more clinical

I will switch to copper to determine my preference

X1 run-in almost 400 hrs ....

Keen to know your feedback after you switched to fiber.....

My X1 has been running non-stop for three weeks or around 504 hours and have never run it on copper having chosen fiber for any possible benefits of galvanic isolation from the network and because I like new technology. I also moved all of my home theater source units and AV processor to fiber as well just in case.

Let us know your preference!

Hi Pete
I m using the 1st order of SFP from fs.com
My 2nd order of 10km is arriving on 9th

Please define different. I do respect your opinion and want to make sure I am using the correct infrastructure.

Gosh if every sfp sounds different then we will be collecting loads of modules in no time lol...

We roll tubes so now maybe it's time to roll SFPs. On a lighter note, I am beginning to get concerned that the fuse in the X1's power supply can be improved but, of course, I am saying this with a certain amount of sarcasm because I have never been able to hear the difference a fuse makes.

Thanks Peter. I appreciate the info.

Just to confirm, you are using an SFP+ in both the CISCO switch and the QNAP NAS and appropriate fiber to connect the switch and the NAS? I may have been reading too deeply but the switch and the NAS should use the same SFPs (at least they do in my system).

The Cisco switch is SFP port and I am using SFP module.
The NAS port is SFP+ and I tried using SFP module and the NAS could not be detected
The X1 is using SFP module connected to the Cisco SFP port and is working fine

Does it mean that SFP+ port on the NAS can only handshake with a Switch that has a SFP+ port and not SFP port?

I don't know the answer to that only that I have like SFP modules on my setup. It's worth a try, IMHO, to put the same modules in the NAS and its port on the switch and see.

Just received it. Will test later and update here

Update: NAS still cannot be detected despite using 10km SFP modules on the Cisco and NAS SFP ports (NAS is a SFP+ port)

Looks like both NAS and Switch must have identical SFP or SFP+ ports. Proves that handshake not possible if one port is SFP and the other port is SFP+
I would have thought SFP+ port can support SFP modules

I have used these in several older Dell Servers and they were easy to install and setup, and work perfectly. I added several of these to connect to a Ubiquiti 10gig aggregation switch and everything communicated with each other without issue and at the speeds expected.
Also I have used products from Gtek multiple times now and everything has been smooth and simple.

Also i check there are all good in compatible with cisco： https://www.sfpcables.com/10gsfp-tra...r-axs13-192-10
platform is much cheaper than Amazon

Peter,

It was good to meet at the Hong Kong AV show this weekend. As i told you, your involvement here is stellar. I know of no other manufacturer who has a rep who is so helpful to forum members. On that point alone, Lumin is worth supporting.

Cheers

Regardless of the controversy, Michael Jackson's music is timeless and wonderful especially Eddie Van Halen's guitar licks on "Beat It".

Let's hope we don't have to levy trade sanctions on the fibre industry!

Ordered the parts and switched my X1 to optical connection (surprisingly easy, took less than 10 minutes). Sound wise, definitely hearing deeper into the recording already with little burn in. Totally worth trying, costs about as much as low end usb digital audio cable.

You know what would be great? A Lumin L1 with optical SFP connection!!!

Peter,

I have a 75' copper Ethernet cable run to my stereo component area. With all that copper Ethernet cable, would I improve the sound quality by using the optical port of the X1? Is there a difference in the sound quality in using a gigabit switch with a fibre port vs. the FMC method?

Thanks,
Brian ...

If I use the fiber optic connection, would having the Uptone Etherregen switch upstream of it provide any additional benefit? Apparently, it improves SQ for copper ethernet. What do you all think?
