I am under the impression that you should use optical for 10GbE networking because of a BER (bit error rate) several orders of magnitude lower than copper.
I'm pretty sure I previously found documentation stating so, but for the life of me I just cannot find it.
I'd like to see documentation on typical BER (in general, if such a thing exists) for:
- 10GBase-T ports (with Cat6a cabling)
- 10GBase-CX4 ports
- 10GBase-T SFP+ modules (Cat6a cabling)
- Fiber SFP+ SR modules
- DAC SFP+ modules
