Confusion in EX9200 port numbering

I need help to understand port numbering in EX9200. I don't understand how come there is ge-1/1/3 and xe-1/1/3 at the same time.

The naming convention is node/linecard/physical port.

How come in the same place i have a 1G and 10G port?

ge-1/1/3 {

native-vlan-id 1;

unit 0 {

family ethernet-switching {

interface-mode trunk;

vlan {

members all;

}

storm-control default;

}

}

}

xe-1/1/3 {

disable;

native-vlan-id 1;

unit 0 {

family ethernet-switching {

interface-mode trunk;

vlan {

members all;

}

storm-control default;

}

}

}
