Steps to Repair Fiber Optic Cable

Step 1: Use OTDR to Identify the Break in Fiber Optic Cable

The first thing you need to do is to look for the break in your fiber optic cables. Commonly, the fiber-optic technicians utilize a device which is known as an OTDR. With the ability to work like radar which sends a light pulse right down to the optical fiber cable. It will be deflected to your device when it encounters break. It helps technician know the position of the break.

Step 2: Use Fiber Optic Cutter to Cut Out the Damaged Fiber Optic Cable

After knowing the location of the break, you should dig up the fiber optic cables with the break. The fiber optic cutter is used to cut out the damaged section.

Step 3: Strip the Fiber Optic Cable by Fiber Optic Stripper

You should use fiber optic stripper to strip the fiber on the both end and peel the jacket gently to expose the fiber-optic tube inside. Then, cut any sheath and yarn by fiber optic cutting tools.

Step 4: Trim Any Damage on the Optical Fiber Ends by High Precision Fiber Cleaver

The following picture lists the main 6 steps for fiber cleaving by high precision fiber cleaver.

Step 5: Clean the Striped Fiber Optic Cable

This step is crucial to ensure that your terminal will get a clean wire strip. You have to clean the stripped fiber with alcohol and lint-free wipes. Ensure that the fiber doesn’t touch anything.

Step 6: Splice the Fiber Optic Cable

Generally, there are two methods to splice optical fiber cable: (1) mechanical splicing; (2) fusion splicing.

(1) Mechanical Splicing

If you want to produce a mechanical connection, you need to put inline splice quick-connect fiber-optic connectors to the fiber. Hold the two fiber ends in a precisely aligned position thus enabling light to pass from one fiber into the other. (Typical loss: 0.3 dB)

(2) Fusion Splicing

In fusion splicing, a fusion splicer is used to precisely align the two fiber ends. You have to convey a fusion splice protector to the fiber, and place the fibers which is spliced within the fusion splicer. Then, the fiber ends are “fused” or “welded” together using some type of heat or electric arc. This produces a continuous connection between the fibers enabling very low loss light transmission. (Typical loss: 0.1 dB)

Step 7: Perform the Connection Test of Fiber Optic Cable with OTDR

The very last thing would be to see the connection of fiber-optic using the OTDR. Then put back those splices into the splice enclosure. Close the enclosure after which rebury the fiber optic cables.
