No Need to Break Down the Wall! New Solution!

      When you just finished setting up your conference room and are about to start a video conference, the TV has no signal. After checking all the devices, you found out that the fiber HDMI cable was reversed.


      Fiber HDMI cable has directionality, with SOURCE and DISPLAY signs on each plug. The SOURCE end connects to the signal source such as a player, while the DISPLAY end connects to the display such as a projector. Once the cable is reversed, there will be no signal.


      The consequences of reversing the cable are serious. The cable has been pre-embedded in the wall. To remove it completely, you have to break down the wall, which is too costly.

      The second solution is to use a new bridgee fiber optic cable to replace the reversed plugs and perform fusion splicing. Moreover, H18D is a design with detachable heads, which is particularly beneficial for threading and wiring.


      Fusion splicing requires a professional telecommunications master to operate. You can call the telecommunications to make an appointment with the master in advance and communicate the fusion splicing requirements to them. The master will bring the necessary tools.


      The tools prepared by the master include a knife, fiber stripping pliers, fiber cutting knife, heat shrinkable tube, PVC tube, fusion splicer, and insulating tape.


      First, use scissors to cut off the plugs that need to be replaced, and use fiber stripping pliers to strip the cable sheath of the intact cable. Then, strip off the bare fiber coating to expose the transparent fiber core.


      Insert the heat shrinkable tube into one side of the bare fiber, use a fiber cutting knife to cut the bare fiber end faces at both ends flat, and then put the cut bare fibers of the same color into the fusion splicer and fix them on the machine.


      Then, turn on the fusion splicer, select "Auto" mode + "SM" fiber type, and wait for the fusion splicing to be successful. After that, put the fiber just now into the heat shrinkable tube for heating.


      Next, repeat the above steps (stripping, cutting the end face, inserting the heat shrinkable tube, and fusion splicing) until all fibers are spliced.

      Unwrap the aluminum foil, strip the cable sheath off the copper wire at both ends, and cut a few pieces of insulating heat-shrinkable tubes to put on one side of the copper wire.


      Twist the two copper wires together, solder and fix them with an electric iron, and then put the insulating heat-shrinkable tube on the soldered position.


      Evenly heat and fix all insulating heat-shrinkable tubes, put the fused part and the exposed cable into the PVC tube, and wrap and fix them with insulating tape.


      At this point, the fusion repair is successfully completed.

      Insert the repaired plugs into the computer and TV respectively, and you can see that the video images are very clear and smooth. H18D has a resolution of 4K@60Hz, and the resolution and smoothness are both outstanding.


      Fusion splicing is an economical and effective method, which is an effective way to solve the problems of fiber optic cable reversal or breakage. I hope this can help everyone.
