Hello community I would love to hear you thoughts on 10G BASE-T SFP+ modules and any problems you may have experienced with them. Example module in the below link. https://www.fs.com/uk/products/66613.html?gclid=EAIaIQobChMI94aH06Xu4AIV9iCtBh04aAdDEAAYASAAEgKNA_D_BwE
Cisco Systems do not sell them however you can purchase them from companies such as the one above who have very good reviews.
From the reading I have done they may not be compliant to the SFP+ power specifications. 10GBASE-T solutions will consume around 4-6 Watts per port. Compared that to the 0.5-1 Watt for SFP+ based solutions.
I have heard that these modules run very hot and was wondering what the gotchas were of using these as I’m sure Cisco would be selling them and making money from them if they could.
My speculation is that if the modules require more power than the switch can offer you may run into situations when you have the switch fully loaded and some ports will suffer as they are not be getting there full allocation of the power. Potentially meaning that some of the ports cannot be used or because the necessary power to the 10G base T module cannot be achieved, you will have issues with the cable length you can use.
Cisco offer the 1Gb option and short 10gb twinax cables which fit within the power specification of SFP+ which reinforces my belief that the reason Cisco do not sell the modules is due to this power issue.
Would be great to hear your stories
