Logical 1 indicates that La-
ser Shut-Down is active.
A low signal switches the
laser on.
A high signal switches the
laser off.
If not connected the Tx is
disabled.
Mod-Def 2 is the data line
of two wire serial interface
for serial ID.
Mod-Def 1 is the clock line
of two wire serial interface
for serial ID.
Mod-Def 0 is grounded by
the module to indicate that
the module is present.
Normal Operation: Logic
“0” Output, represents
that light is present at re-
ceiver input.
Fault Condition: Logic “1”
