As a reliable supplier of fiber cleavers, I'm often asked about the cleaving process of a fiber cleaver. In this blog post, I'll walk you through the step-by-step process of using a fiber cleaver to achieve clean and precise fiber cuts.
Step 1: Prepare the Fiber
The first step in the cleaving process is to prepare the fiber. This involves stripping the protective coating from the fiber to expose the bare glass. You can use a fiber stripper tool to carefully remove the coating without damaging the fiber. Make sure to clean the stripped fiber using isopropyl alcohol and a lint-free wipe to remove any dirt or debris.
Step 2: Measure and Mark the Fiber
Once the fiber is prepared, you need to measure and mark the length of the fiber that you want to cleave. Use a fiber optic ruler or a cleaver with a built-in measuring scale to determine the desired length. Mark the fiber at the appropriate point using a fiber marker or a piece of tape.
Step 3: Load the Fiber into the Cleaver
After measuring and marking the fiber, it's time to load the fiber into the cleaver. Open the cleaver's fiber holder and carefully place the fiber into the groove, aligning the marked point with the cleaving blade. Make sure the fiber is properly seated and secured in the holder to prevent any movement during the cleaving process.
Step 4: Adjust the Cleaving Parameters
Before cleaving the fiber, you may need to adjust the cleaving parameters on the cleaver. These parameters include the blade pressure, cleaving angle, and blade position. Refer to the cleaver's user manual for specific instructions on how to adjust these parameters based on the type and diameter of the fiber you are cleaving.
Step 5: Cleave the Fiber
Once the fiber is loaded and the cleaving parameters are adjusted, you're ready to cleave the fiber. Close the cleaver's cover to engage the cleaving blade. The cleaver will apply a precise amount of pressure to the fiber, causing it to break cleanly at the marked point. The cleaving process is usually quick and automatic, but some cleavers may require you to manually operate a lever or button to initiate the cleave.
Step 6: Inspect the Cleaved Fiber
After cleaving the fiber, it's important to inspect the cleaved end to ensure a clean and smooth surface. Use a fiber microscope or a cleaver with a built-in inspection system to examine the cleaved end. Look for any signs of cracks, chips, or irregularities that could affect the performance of the fiber connection. If the cleaved end is not satisfactory, you may need to repeat the cleaving process.
Step 7: Clean and Protect the Cleaved Fiber
Once you're satisfied with the cleaved end, clean the fiber again using isopropyl alcohol and a lint-free wipe to remove any debris or residue. Then, protect the cleaved end by covering it with a fiber end cap or a dust plug to prevent contamination.
Step 8: Store or Use the Cleaved Fiber
Finally, you can store the cleaved fiber in a fiber storage container or use it immediately for splicing or termination. Make sure to handle the cleaved fiber carefully to avoid damaging the end surface.
