disable interface TX laser (JUNOS)

Just in case if you want to simulate a fiber cut, you can enter a command from the FPC shell that cuts the power to the laser of an interface

start shell pfe network fpcX

test xfp <index> laser off

You can find the XFP index by doing "show xfp list" from the shell prompt.  I haven't seen a method that works for SFP interfaces.

For sonet interfaces, this hidden configuration is also an option:

set interfaces so-x/y/z sonet-options insert-los
