First Operation - THORLABS INT-COM-1300 Operation Manual

2 Getting Started Quickly

2.3 First Operation

• Please note, that all fiber connectors must have a FC/APC connector!
• Connect a swept laser source to 1300nm IN.
• If necessary, connect a 660nm aiming laser to 660nm IN.
• Connect your Common Path interferometer probe to PROBE.
• Connect an external variable optical attenuator (VOA) to VOA IN and
VOA OUT.
• Adjust the external VOA to suppress any DC component in the interference
signal.
• The maximum OUTPUT voltage swing is ±3.6 V for high impedance loads
(±1.8V for 50Ω loads). The OUTPUT signal should not exceed this maximum
output voltage to avoid saturation.
Clean all connectors before plug-in into the module. Please make sure,
To prevent saturation of the amplifier keep the optical input powers less
Refer to the specification and pay attention to the optical damage
Exceeding these values will permanently destroy the detectors!
