From documentation it is not very clear. Will CCR1036-12G-4S router work with 10Gb SFP+ cable, at the rate of 10Gb ? I want to connect this router to a switch : Quanta LB6M using this type of SFP+ cable : S+DA0003. Will such configuration work ?

Any help will be greatly appreciated

Thanks

This one has only SFP ports, you need SFP+ for 10Gbit

This one, for example, has two SFP+ ports with 10Gb module support:

normis,

I also have this router CCR1009-8G-1S-1S+, so it has a SFP+ port. Is the cable S+DA0003 ok to interconnect the router to this switch : Quanta LB6M ?

If this device has no vendor lock in, it should work fine
