Every clean splice follows the same workflow. Skip a step and you'll pay for it on the OTDR.
[ Step 01 ]
Inspect the fiber
Why it matters:Look for damage, kinks, or contamination before you start. A bad piece of fiber will never give you a good splice — cut it back to clean glass first.
◆Pro Tip
Use 99% isopropyl alcohol and fresh lint-free fiber wipes. Anything weaker (rubbing alcohol from the drug store) leaves water and additives behind that contaminate the splice.
