The whole idea of that umbilical still gives me the yips for some reason. I suppose this design was Samsung's way of hiding the multitude of cables that usually connect between the TV and the various input sources. I'm guessing that the should-be-waaay-overkill two pairs of fiber probably mimics the architecture of the copper medium. If I were faced with the problem at hand, I’d first hunt for the copper version of the connector. Poking around a bit now, it looks to me like the subject of this article is a special implementation of the umbilical to make it even less obtrusive/ugly. I recall being unpleasantly surprised by the architecture of that somewhat chunky cable sitting between that stupid looking box and the giant screen we were hoisting up onto the wall. I installed one of these flavors of TV several years ago. The devil’s in the details but the process itself is conceptually as simple as it gets. The arc energy determines the temperature but has to be adjusted to compensate as the electrode tips wear, and of course it also depends on ambient temperature and humidity and barometric pressure and everything else. The specific details of the timing and motion are super important to the final quality of the splice, since too much force will make a bulge, too little makes the splice mechanically weak, any lateral skew causes a step-misalignment, etc. Just as they’re approaching molten, the fine motion stage in the machine “kisses” the ends together, and they fuse into one. The electrodes strike an arc which heats the ends of the fibers. Why reinvent the wheel? Are they making that much money on selling replacement cables, or just forcing perfectly good TVs into the scrap heap?įor anyone not familiar with how fusion splicing actually works, this video is a very quick, but very good, intro: Shame Samsung didn’t just an MPO connector or a simple QSFP DAC or something. Posted in Repair Hacks Tagged cable repair, fiber optic, fusion splicer Post navigation This might be the first fiber-optic splicing attempt we’ve seen but if you’re trying to hook up an optical fiber to your circuit, this ball lens setup is a neat trick. Once this was complete, it was a matter of covering the splices to protect them from sharp bends, and the fancy TV was working again.Īlthough not everyone will have access to a multi-mode fusion splicer machine, ’s videos provide fascinating insights into the workings of modern fiber-optic based consumer electronics. This is a rather neat piece of equipment that semi-automatically brings two pieces of fiber together and welds them with an electric arc. For the other two, a combination of reverse-engineering the electronic circuits and some systematic trial-and-error yielded a complete wiring diagram.įor the second part, called on a fiber optic expert who lent him a fusion splicer. One clever trick was pointing a camera at a working cable and comparing the flashing lights at each end this helped to identify the right order for two of the four pairs. The first was difficult enough: a simple 1:1 connection didn’t work, so it took a bit of work to figure out the correct connection setup. Repairing the cable required two things: figuring out which fibers should connect to each other, and a reliable way of connecting them together. The cable consists of four pairs of plastic-coated glass fibers, which are attached to receivers and transmitters inside the thick connectors on either end. Replacement cables are quite expensive, so went on to investigate the inner workings of the fiber optic cable and figured out how to repair a broken one. Thin fiber optic cables are fragile however when got one of these TVs for a very low price it turned out that this was because its One Connect cable had snapped. In some versions, the cable linking the TV with its Connect Box is a pure fiber optic cable that’s nearly transparent and therefore easy to hide. Some Samsung TVs come with a system called One Connect, where all external cabling is connected to a separate box so that only one small signal cable goes to the TV.
