Fiber Fusion Splicer AI-9

I've waited a year and about 1000 splices to write this review. I have 13 years of experience using at least a dozen different machines. I originally bought this splicer as a cheap option for starting my business. Even though I own a used Fujikura 70S now, it sits in my office and I STILL use the SignalFire. I like the small case, though I'm way too tall to find the stool useful so it's in the garage on a shelf. The important thing to remember is that it's a little finicky and requires regular cleaning and calibration. the cleaver is the same way, pretty solid but requires maintenance and adjustment more than some others. With regular maintenance, it's been really reliable for me and my splices test out great. I would really like some sort of arm to close the heater automatically, rather than having to align the splice with 4 fingers and close it with a 5th but I have gotten used to it and it doesn't really bother me anymore. The other problem with the heater is if you let the sleeve fall to the bottom, it can pinch grooves into the sleeve but holding it while you close the heater solves that problem. I'd also be willing to pay a little bit more for a built in UI with a touch screen; I'm not a big fan of the app, though it works alright. On a scale of the best splice machines I've used, it's probably a 3.5 star machine (beating every INNO I've tried by a mile). The reason for 5 stars is the price to value ratio. Absolutely worth it. Overall, I'm very surprised and impressed with how functional it is at this price.

Been a solid 25 years since I touched fiber. One of my techs gave me an estimate on how long to terminate 12 strand 50/125 om4 pigtails, that I thought was overly high, so I bought this kit. With some added shrink tubes and a few minutes on Signalfire videos, I has my first strand spliced in about 20 minutes, getting used to the tiny fiber mostly. After a couple hours, was terminating a strand every few minutes. App is easy to use, setup and function are great. None have been over 0.01db and all are working well passing 10GB with LC to LC jumpers. System will not splice without good cleaves and alignment, fun to watch auto functions run. Hot melt won't fire only fusion is good. Only complaint could be that the hot melt for the shrink tube sometimes melts the jacket too. Getting more splices out of these tips than another more expensive brand. Was able to show guys who never spliced before how to do so in about 15 minutes. We will be using more of these kits and this brand.

Very good!

Outstanding fushion splicer for the money. Punches way above its weight and does everything I need that my fujikura does.

its the best bang for your buck when it comes to light fiber work. it is not a production level splicer like the fuji or sumo's. it gets the job done and the burns are well within the 0.01-0.04 range. it does say 0.00 on the losses for just about every splice I've done, but it's a liar because I intentional damaged my bare fiber a few times after calibrating it and could see how shotty it was when it zoomed in and it still fused it. so i will say that it isnt very picky either. it will burn just about anything so be sure to invest in a decent cleaver at the very least and you should be fine. but again, this isnt a precision brand. its a cheapo spare you keep when the main splicer is down or sent to repair. it gets the job done well within the tolerances.

Excellent product for the price. Instructions were almost impossible to follow I found. That said, strip it, cleave it, insert it and DONE. The app on the phone is imperative to make any changes to default settings. Connecting with Bluetooth was hit or miss with my IPhone.....it would connect, then drop, then could not reconnect....That was certainly frustrating. All that said, VERY happy with this purchase. Once you get the process down, it's very simple to use. I've done 50 burns so far. UPDATE.. After about 250 burns I've run into some problems. The unit will no longer run on the battery alone: it needs to be plugged in order for it to stay turned on. As well, the fiber sleds are not bringing the strands close enough to get a proper burn. I can't seem to calibrate it. It's taking 6 or 7 attempts to even get the fibers welded and when they do, the are VERY delicate and high loss. For the price I paid, I got my money out of it. Rather than mess around further I'm just going to buy another unit.

Muy buena maquina rápida cumple con todo el detalle que ami me enviaron otro tipo de cleaver y no la que salía en la imagen. Aunque igual muy buena

Had to get a different cleaver. The S09 that came with it, wasn't possible to adjust the blade high enough in order for it to cleave. Wasted an entire day with a client trying to get it high enough to cleave. Terrible imprecise cleaver. Not even going to use the splicer now. Going back to my old one. Waste of money and I'm past the return window.

Works good but temperature and humidity seems to affect its quality of splice.

This is my second one from this brand. The old one is stuck in the artic circle awaiting shipping, so I bought a new one to use for now. Works just like the beldon or corning brands, or even the fujikura ones. Haven't had to use holders for fiber connectors, just plain old pig tails and splice tube's. Easy enough to use that i had several electricians try splices and they did ok. Great bang for the buck, just get a good fiber fox or other brand of cleaver before too long.
