FS.com suggests 17€ for 10GBASE-SR, and 4€ for 1m of OM3, or ~40€ total, with three different components that could be a point of failure, in many weird and wonderful ways, vs ~10€ for a 1m 10G DAC, which is sold as a single unit and is replaced entirely in the event of a failure.
DAC is also lower latency at these short distances too, as you don’t need to convert electrical to optical and back again. It’s just end to end electrical.
