When our fiber optic cable is accidentally disconnected, how to splice it? Recently, many customers have asked how to splice it by themselves when the fiber optic cable is disconnected. Then let our professional technology of Oplink tell you how to splice the disconnected fiber optic cable.
1. When connecting, you need to choose the same color system, connect concentrically, and then connect in order from large to small. When connecting, please unplug the optical cable first and peel off 1mm. If there is grease in it, please wipe it off with paper first.
2. Pass the stripped optical fiber through the junction box, and fix it tightly with needle-nose pliers. Then, run the fiber through the tubing, keeping an eye out for the different lines and the different color separations. If there is a hot fuse, it can be welded with a welding machine. After the power is turned on, the welding will be successful automatically, and the cracking problem can be avoided in the later stage.
3. Take out the optical cable, seal and store it, take waterproof measures, and check whether the net is unblocked.
4. The optical cable is broken, don't worry. If conditions permit, welding methods can also be used. If you don’t know and don’t have relevant equipment, it’s safer and more reliable to invite experts to come to your home to connect.
Fiber-optic entry uses leather fiber optic cables, and cold contacts are used at the end. Cold welding refers to stripping the optical fiber to cut it, and aligning it with cold welding to fix it. Cold splicing is more convenient and does not require a fusion splicer.
Cold splicing mainly includes five steps: stripping, cleaning, cutting, cold splicing and testing:
1.Remove the cold compress tail tube, and pass the optical fiber through the tail tube.
2. Use an open column to peel off the PVC layer and cut off the ribs at the same time.
3. Clean the exposed fibers with a non-woven cloth soaked in absolute alcohol.
4. Use the fiber optic cutting edge fixture table to cut off the fiber optic clamp together with the fiber.
5. Pass the fiber through the cold junction body.
6. Use a fiber optic test pen to test the continuity.
The difference between cold splicing and thermal fusion splicing of optical fibers:
1. Melting
To use the fiber fusion splicer and fiber splitter, two optical fibers need to be connected, and no other auxiliary materials are required. It has the advantages of stable quality and low connection loss (about 0.05 to 0.08db), but has the disadvantages of high equipment cost, limited energy storage capacity of equipment, and limited outdoor work. In short, the welding quality is good and the attenuation is low, but the operation is troublesome and requires a welding machine.
2. Cold connection
Not a lot of equipment is needed, just a fiber cutter, but each contact needs a quick connector. It has the advantages of convenient operation and suitable for outdoor work, but the disadvantage is that the loss is relatively large. "About 0.2-0.5db cold junction at each point" has no choice in business and technical services. In short, the aging problem needs to be tested over time.
