Detecting cable in a SFP/SFP+ Port

Hi

Is there a way to detect if a cable is plugged in a SFP/SFP+ port?

​

Please note I am not looking for solutions that tell if a link is present (like ethtool eth0 or /sys/class/net/eth0/carrier). I want to know if a cable is plugged in even if its other end is dangling or powered down.

​

Thanks
