The optical power alarm LED is normally green. It turns red
on insufficient optical power. Optical ouput reads as shown below:
The laser current alarm LED is normally green. It turns red
on excessive laser current. At a typical laser current of 50mA the TP
will read 1.0V.
The cooler alarm LED is normally green. It turns red when
the cooler cannot keep the laser at a constant temperature.
The RF level adjust control allows for a 4dB range of input
level adjustment.
The RF test point is calibrated to read +10dBmV @ 25MHz
for proper laser modulation with 6 channel loading. This level will
change with channel loading. It does not require termination.
The optical output connector is type SC/APC, with optional
FC/APC connector available.
INDICATORS AND TEST POINTS FOR LP-OT-10-RCxx
The laser transmitter has front panel test points for optical power and laser current. Only a high impedance
voltmeter should be used. The meter common should be connected to the module ground test point, not to chassis
ground.
