I don't know how that Synology DS423+ could consume 50W idle.
It seems veeery strange to me. I mean, my E5-2620 V2 on a 10/15 years old Supermicro motherboard with 16GB of RAM, 4 idle SATA 3,5" hard drives and 2 SSD is consuming 55W!
Something doesn't sound right to me.
My Internet provider just installed a 2,5/1Gbps Internet connection and I've asked the guys to run a couple of their fiber to connect my router (HP Prodesk with OPNsense) to my server....
Regarding future proofing, I would say that anyone laying single pairs of fibres is already going to constrain themselves when looking to the future.
It could be right, but it depends on what people can run in the conducts. I was lucky to be able to pull those 2 cables.
On the other hand, this is a rent apartment that I will soon leave :D
GPON adopts WDM to transmit data of different upstream/downstream wavelengths over the same ODN. Wavelengths range from 1290 - 1330 nm in the upstream direction and from 1480 - 1500 nm in the downstream direction.
So I guess that all the single mode SFP+ that have that range are ok.
Do I have that right? If so, my advice would be to identify the wavelength of that fibre, which can be found printed on the outer jacket. Do not rely on just the color of the jacket, and do not rely on whatever connector is terminating the fibre. The printed label is the final authority.
You got it right!
On the cable unfortunately there is no wavelength printed (it's a cable made for my ISP), but I've read on a forum (that talks about this ISP):

Edit: In the meanwhile, do you have any 2,5Gbe PCI card that you suggest (I need it to connect OPNsense to the ONT via PPPoE)? I've found only the QNAP QXG-2G1T-I225 that costs about 75€ or the Edimax EN-9225TX-E for about 41€ (but I haven't read much about this one).
Thanks for your precision!
To the ONT arrives a single fiber with a SC/APC connector, but this is not a problem since I will be using the ONT provided and use the 2,5Gb copper port to connect it to OPNsense (looking for a 2,5 Gb PCI card).
The 2 fiber that I've asked them to run (from OPNsense to server) are terminated with the same SC/APC connectors and I was thinking about using this SC female/female adapter and this SC/APC to LC cable that I've just realized that are still APC...I'll have a look if there are SC/APC to LC/UPC cables
As for that xcvr, please note that it’s an LRM, or Long Range Multimode xcvr. Would it probably work at 30 meters? Probably. But an LR xcvr that is single mode 1310 nm would be ideal.
Is it a LRM? Damn, I didn't realized since I've filtered for single mode. If the filter doesn't work, I've no idea which is LR. Would you be so gentle to point to a cheap one for single mode finer?
Although your ISP was kind enough to run this fibre for you, the price of 30 meters LC/UPC terminated fibre isn’t terribly excessive (at least here in USA), so would it be possible to use their fibre as a pull-string to run new fibre instead? That would avoid all the adapters, although you’d have to be handy and careful with the pull forces allowed on a fibre.
The problem is the installation of the connectors. They've welded the fiber the SC/APC pigtails, I wouldn't be able to do that.
The big manufacturers (Cisco, HPE/Aruba, etc) will have detailed spec sheets, so you can find the branded one that works for you. And then you can cross-reference that to cheaper, generic, compatible xcvrs.
That would be very very generous of you; in the fiber section I'm pretty ignorant and I'm worried to purchase wrong items 🙈
I have the whole OS on that RAID.
Should I just create the new MD and copy everything there? I guess that I need to copy data when the OS is shut down (so with another PC), correct?
Oh, so easy?!
If the RAID rebuilds the disk, why should I install a bootloader? Isn't it already in the rebuilt disk?
By the way...hemmm...how do I install the bootloader? 😣
Network Device Interface: basically it's an audio/video (and intercom) transmission over IP with low latency. The sender could be an hardware encoder or a software that I could install on a Windows VM and use on that machine Jellyfin and Netflix
Kinda, the difference is that you don't need to take the output of the graphics card (so no need to run X), but you can send the video directly from a software.
Because do this kind of thing is fun! 😁
And since I share the Netflix account with my siblings, I can only watch it on a PC (with Edge to have 4K 🙈).
...but I'll keep the Roku option in mind. Thanks
Since I'm sharing the Netflix account with my siblings, I can't use a smart TV, a Roku or another player but just a browser, because the hardware players should all be using the same Internet connection.
