> (they're also dramatically less expensive)

It depends, but for typical networking I'd say Ubiquti is actually offering better pricing here (outside of 10G LR) - and I'm saying that as someone who has sold 10s of thousands of FS modules to customers.

             |  FS  | Ubiquiti
  -----------+------+-----------
  Programmer | $369 | $49
  10G SR     | $25  | $12 ($20)
  10G LR     | $34  | $59 ($85)
  25G SR     | $49  | $29 ($49)
  25G LR     | $74  | $69 ($119)
  100G SR4   | $99  | $39 ($69)
Note: Prices in () are the costs outside of the limited time mark-down period.

Side note for the HN crowd: For ridiculous homelab 100G shenanigans look for Intel 100G-CWDM4 on sites like Ebay. They go for $4 and work with SM LC fiber from 0-2000 meter runs, making great DAC replacements (cheaper+thinner replaceable cabling). They run great, I've had 8 going for a year. Even if all 8 failed tomorrow and I bought 8 more that's still cheaper than a single 100G SR4 from FS. You can pair these with used 100G NICs for ~$100, making a 100G direct connection between 2 machines ~$250 after shipping+tax.



For high speed home stuff, I usually pick up some old Mellanox infiniband cards and cables. They're usually dirt cheap and insanely quick. Difficult to work with if you do not know what your are doing.


OMG, mlx fw upgrades.

I'm so happy my current employer chose sfc :)


Lol.. yeah. Was fun having a 32Gb (QDR) storage network at home for next to nothing for a while (except the huge electric bill).

Ubiquiti's 10GB LR of $59 is for a 2-pack, not per-module. So that still comes out cheaper than FS for the sale duration at least. Not by a lot, granted, but still cheaper.


Whats the best solution for short runs (rack) between Mikrotik switches and Dell servers. Will a DAC still work between different vendors or is it always best to buy individual transceivers?


DAC is always the best option for short runs in terms of cost and compatibility.


Agreed. I have a 10 Gb DAC connecting my workstation and a small server to a Mikrotik. They are way cheaper, use less electric, and run cooler compared to a UTP SFP. I don't like UTP for 10Gb as its both costly and less efficient though that is going to get better with time.


It won’t get much better because that’s just a limitation of how 10GBASE-T works. There’s never a good reason to use it. Always just use a DAC or fibre.


Fun fact: each one also consumes approximately $4 in electricity per year.

Assuming 2.5W typical consumption, $0.18/kWh rate. More like $8/year if you are in a high rate area!


Nice prices from Ubiquiti. I think fs mostly competes against Cisco which have much higher prices. IIRC we hade like a 95% discount off Ciscos list price for optics.
