Using Ethernet cable in SFP+ Port

No, you need to put an SFP transceiver in the port, and then you plug the cable into the transceiver.

A RJ45 (Ethernet) connector will kinda fit in a SFP+ port, but it won't work because the wires won't get connected. It's like plugging USB into an Ethernet (RJ45) port.

An SFP(+) port requires a PHY module unless it's used with a direct-attach cable (DAC) that has fixed SFP+ modules at its ends.

Not all SFP/SFP+ ports support 1000BASE-T modules. Quite a few SFP+ ports don't support 10GBASE-T (and if they do the reach is normally reduced to 30 m or so).

In any case, you'll need to check the device documentation for compatible modules. Most vendors also try to force you to use "original" modules, so you'll make sure the module at hand shows the required brand as well.

Assuming you have compatible SFP-T transceivers, Yes.
