• Mode-Hop Errors: During fine wavelength tuning, mode-hop errors may occur, leading to abrupt and unexpected changes in the output wavelength. This can impact measurement accuracy and consistency, especially when performing tests on components that require stable and precise wavelength settings.
• Output Power Instability: Users may experience fluctuations in output power over time, particularly in environments with significant temperature variations. This power instability can affect the accuracy of test results and may require recalibration or the use of an optical attenuator to maintain consistency.
• Wavelength Accuracy Drift: Over time and without regular calibration, the accuracy of the wavelength output can drift, leading to measurements that do not align with the intended wavelength specifications. This drift can affect the precision of tests, particularly those that require exact wavelength positioning.
• Back Reflection and Interference: Improperly terminated fibers or connectors with high back reflection can cause interference and instability in the laser’s output. This can result in erroneous readings and potential damage to the laser source due to reflected power.
• Laser Overheating: Continuous operation or operation outside the specified environmental conditions can lead to overheating. The Agilent 81960A is equipped with protective mechanisms that may trigger automatic shutdown to prevent damage, causing interruptions in testing.
• Connector Mismatch Errors: Using connectors that are not compatible with the tunable laser’s output interface (e.g., using angled connectors with a straight contact laser module) can lead to increased insertion loss, reflection issues, and potential damage to both the connectors and the laser source.
• Alignment and Polarization Issues: In systems where polarization maintaining fibers are used, improper alignment of the fiber’s polarization axis with the laser’s output can result in inconsistent measurements and reduced signal quality. This issue may be indicated by poor extinction ratios or unexpected power losses.
• Error Codes and System Warnings: The laser module may generate specific error codes or warnings related to faults in the laser control system, power supply issues, or other internal diagnostics. These codes typically require consulting the user manual for troubleshooting steps.
• Laser Safety Error: Laser modules eventually require repairs and adjustments after years of use. The laser safety error is extremely common in occurrence which will cause your laser module to have no light output. The laser control circuit switched off the laser because of two possible reasons. Either the laser current or the laser power was too high.
