I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can’t find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I’d day 2 4K simultaneously) that is only...
Yes, I would install the video cars in the second PCI slot, but the motherboard has an integrated video card, does that count? By the way, I don’t have alternatives, if it will not boot, I will not use the graphic card. Thanks!
This is very interesting, thsni thanks! How fast are the base stations? Is it all down to the smartphone speed to connect to a BT device? What smartphone are you using?
Are there any individuals or services that will build a custom air quality sensor from individual components for a fee? I am mainly interested parties in a couple humidity+temp+co2 boxes (wifi,zigbee,zwave or cable)...
With Google Workspace cracking down on storage (Been using them for unlimited storage for years now) I was lucky to get a limit of 300TBs, but now I have to actually watch what gets stored lol...
100TB??? What the heck did you store in there? A lot of “Linux ISOs”, ok, I get it, but how many GB is each? Some may be 10/20GB, but I guess that most of them are about 2/4GB. Some images of old drives, ok (some TB), and then?
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. I didn’t know that the fiber is single mode and all the SFP+ sold used now seems to be all for multi mode fiber (www.bargainhardware.co.ukfor...
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 🙈
Hi everybody! For my OPNsense router (on a VM on Proxmox) I need a 2,5Gbe card (to connect to the ONT of my provider); I only have 2 PCIe 3.0 x1 or 1 x4 because the only x16 is for a dual SFP+ fiber card....
