Here's how you can effectively troubleshoot and resolve technical issues in Optical Engineering.

When a fault occurs, whether it be a minor or major outage immediately raise a fault ticket to work to. Also, check the NMS platforms to see where the fault has generated from, what alarms and equipment has been affected then you can start to start on diagnosis.

Before diving into repairs, it's essential to diagnose the issue accurately. Start by examining the optical system's performance against expected results. If you notice discrepancies, check for common problems like misalignment, contamination, or component damage. Use diagnostic tools such as interferometers or wavefront sensors to measure the optical wavefront and ensure that all components are functioning correctly. Understanding the symptoms and measuring deviations from normal performance are the first steps to pinpointing the underlying problem.

When an issue occurs on most fiber optic networks typically these steps are followed : 1. Define the affected area geographically. 2. Identify the main cable (Trunk or Distribution) feeding the affected area. 3. Identify the affected area's feed fibers and their point of origin e.g. CO, cell-site, etc. 4. At that point of origin, check and track signal at 1st splice location outside of the patch-panel to rule out equipment and/or mechanical connectivity issues.

A thorough system check is the next logical step. Review the optical setup's alignment using alignment telescopes or autocollimators, ensuring that each element is positioned correctly. Verify that optical surfaces are clean and free from scratches or other defects that could degrade performance. Also, confirm that the mechanical supports are stable and that there are no vibrations or thermal effects causing distortions. Remember that even minor misalignments or impurities can significantly impact the system's functionality.

5. If all good to that point, using an OTDR shoot affected area's feed fiber/s from the patch-panel to localize any issues on those fibers. Corelate any observed issues distances with fiber design and determine specific physical locations, be they at known existing splice locations or not. 6. Visually and physically inspect the fiber cable itself at these problem areas distances. When an issue is found determine and effect best repair, be it simple resplicing and/or replacing cables.

80% of all outages are due to dirty connectors. As a tech you can find that problem really easy by scoping the connectors the fip400 & fip500 are some of the microscopes that are used most of the time. If the connectors have grime on it you can do a hybridcleaning from wet to dry with a solvent like fw2150 / fw2170 or fw2190.

Calibration is absolutely crucial on the fusion splicing side as well. For consistently reliable high quality fusion splices, I perform an "Arc Calibration" with my Fujikura's both in the cooler morning hours and in the hotter afternoon hours. It takes only a few minutes and definitely keeps my fusion splicer dialed-in throughout the day.

Calibration of equipment is needed! When splicing in different environments and with different fibers a splicing machine should behave always in a slightly different way. And arctest is a must in between of dramatically environmentally changes. With testing a yearly calibration is really at its place… and even then it is discussable if the unit is still in calibration. A heavy used otdr can have a damaged connector in several weeks due to bad cleaning! OLTS sets also need a yearly calibration or… there are the MAX945 that are possible to be 3 years in calibration. Every time with setting a reference these units do a self test if they are still in spec.

Calibration is crucial in optical engineering. Ensure that all instruments and measurement devices are calibrated correctly. This includes checking the wavelength accuracy of spectrometers and the focal lengths of lenses. Calibration not only helps in maintaining system accuracy but also in establishing a baseline for future troubleshooting. If issues persist after calibration, it may indicate a more complex problem within the optical system that requires deeper analysis.

Sometimes, technical issues arise from flaws in the optical system's design. Review the design specifications and compare them with the actual setup. Look for discrepancies in material indices, surface curvatures, and element spacing that could lead to performance issues. Understanding the intended design parameters helps you identify if the problem is due to a design oversight or a deviation during implementation. It's also an opportunity to suggest improvements for future iterations.

In my experience, many times light loss in passive devices is forgotten about when trying to add to an existing path. Whether it is trying to upgrade to new equipment while keeping the old running, or an area doesn't have spare fiber for new connections, these losses add up quickly and can push you to the brink of failure.

Once you've made adjustments or repairs, rigorous testing is key. Conduct a series of performance tests under various conditions to ensure that the issue is resolved. This might include checking the image quality, beam profile, or system throughput. Testing should mimic real-world operating conditions as closely as possible to verify that the solution is robust and reliable. Documenting the results of these tests can aid in future troubleshooting efforts and system optimizations.

Regular maintenance can prevent many technical issues from occurring in the first place. Establish a maintenance schedule that includes cleaning optical components, checking for wear and tear, and recalibrating instruments. Preventative maintenance not only extends the life of the optical system but also ensures consistent performance. By keeping a log of maintenance activities and system performance over time, you can detect potential issues before they become significant problems.
