I’m looking to upgrade some of my internal systems to 10 gigabit, and seeing some patchy/conflicting/outdated info. Does anyone have any experience with local fiber? This would be entirely isolated to within my LAN, to enable faster access to my fileserver.

Current existing hardware:

  • MikroTik CSS326-24G-2S+RM, featuring 2 SFP+ ports capable of 10GbE
  • File server with a consumer-grade desktop PC motherboard. I have multiple options for this one going forward, but all will have at least 1 open PCIe x4+ slot
  • This file server already has an LSI SAS x8 card connected to an external DAS
  • Additional consumer-grade desktop PC, also featuring an open PCIe x4 slot.
  • Physical access to run a fiber cable through the ceiling/walls

My primary goal is to have these connected as fast as possible to each other, while also allowing access to the rest of the LAN. I’m reluctant to use Cat6a (which is what these are currently using) due to reports of excessive heat and instability from the SFP+ modules.

As such, I’m willing to run some fiber cables. Here is my current plan, mostly sourced from FS:

  • 2x Supermicro AOC-STGN-i2S / AOC-STGN-i1S (sourced from eBay)
  • 2x Intel E10GSFPSR Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85 for the NIC side)
  • 2x Ubiquiti UF-MM-10G Compatible 10GBASE-SR SFP+ 850nm 300m DOM Duplex LC/UPC MMF Optical Transceiver Module (FS P/N: SFP-10GSR-85, for the switch side)
  • 2x 15m (49ft) Fiber Patch Cable, LC UPC to LC UPC, Duplex, 2 Fibers, Multimode (OM4), Riser (OFNR), 2.0mm, Tight-Buffered, Aqua (FS P/N: OM4LCDX)

I know the cards are x8, but it seems that’s only needed to max out both ports. I will only be using one port on each card.

Are fiber keystone jacks/couplers (FS P/N: KJ-OM4LCDX) a bad idea?

Am I missing something completely? Are these even compatible with each other? I chose Ubiquti for the switch SFP+ since Mikrotik doesn’t vendor-lock, AFAICT.

    It’s my understanding that the vendor branding on FS transceivers is just a string to match what the vendor’s lockout code is looking for. Since Mikrotik doesn’t do that, I went with Ubiquiti in case I decide to move to that in the future.

    Fortunately, the fiber will mostly be running through an unfinished basement. I previously tried to run smurf tube behind finished wall, and it was much harder than it sounded. It’s hard to drill a hole that big, things didn’t line up, and parts of it involved extremely tight quarters. I would contract it out before I’d try it again.
