1. Advanced Stripping Technique
When removing the buffer coating, hold the st****er at a 30-degree angle. This prevents micro-scratches on the glass surface, which are often the hidden cause of fiber breakage later on.
2. High-Precision Cleaning (99% IPA)
Always use 99% pure Isopropyl Alcohol (IPA). Lower-grade alcohol contains water or impurities that leave a residue, which can cause "bubbles" or impurities to be trapped inside the splice.
3. The "One-Touch" Cleaving Rule
Ensure your cleaver is maintained so it cuts perfectly in one go. Aim for an end-face angle of less than 0.5 degrees. If the cleave isn't perfect, re-clean and re-cleave rather than trying to force a bad match.
4. Electrode Maintenance
Check the life of your machine's electrodes regularly. Carbon buildup can cause an unstable arc. After every 1,000 splices, run the machine’s "Electrode Stabilizing" program to ensure a consistent arc.
5. Manual Core Alignment
While auto-alignment is convenient, use Manual Core Alignment for critical long-distance links. This allows you to visually inspect the core on the monitor and ensure the best possible alignment before firing the arc.
6. Real-time Loss Estimation
Check the Estimated Loss on the screen immediately after splicing. If the loss is higher than 0.02 dB or 0.03 dB, it is often better to break and redo the splice to maintain a high-quality link budget.
7. Automated Tension Test
Always perform a Tension Test (Pull Test) using the splicing machine. This ensures that the fusion joint is physically strong and won't snap during the "dressing" process in the tray.
8. Precise Heat Shrink Positioning
Center the splice protector (sleeve) exactly over the joint. Ensure the fiber is perfectly straight when placing it in the heating oven to avoid Micro-bends, which cause significant signal attenuation.
9. Tray Management & Bending Radius
When coiling the fiber into the splice tray, maintain a safe Bending Radius. Avoid loops smaller than 30mm; otherwise, you will encounter "Macro-bending loss" that will show up as a fail during OTDR testing.
10. Digital Documentation
Modern fusion splicers allow you to export data via USB or Bluetooth. Saving the loss data, images, and timestamps for every splice helps in professional reporting and future troubleshooting.
