According to the documentation for SRX1600/SRX2300 PIC 2 1G/10G SFP+ ports are named xe-0/2/0 - xe-0/2/3

https://www.juniper.net/documentation/us/en/software/junos/interfaces-security-devices/interfaces-security-devices.pdf

However when we used 1G module, interface name is ge-0/2/0, not xe-0/2/0. Is it correct behavior (but incorrect documentation) or the opposite?

On SRX1600/2300, when you plug in a 1g SFP in a port which supports both 1g and 10g SFPs, the name will show up as Ge, and when you connect a 10G SFP then it will show up as Xe interface.

On SRX1600/2300, when you plug in a 1g SFP in a port which supports both 1g and 10g SFPs, the name will show up as Ge, and when you connect an 10G SFP then it will show up as Xe interface.

This is an expected behavior with the new Junos code.

Starting in Junos OS Release 24.2R1, you have two configuration options in PIC mode: 1GbE/10GbE combined and 25GbE. You can configure the SFP28 ports in two ways:

1). If you select 1GbE/10GbE mode, the SFP28 ports can choose either 1GbE or 10GbE.

2). If you select 25GbE mode, the SFP28 ports run on 25GbE.
