Testing LC to LC Duplex Fibers (DTX FI 103) – By Fluke Networks

On this video, i will exhibit you tips on how to certify an LC to LC duplex link, utilising the one jumper reference, The GTX CableAnalyzer with the sequence 2 fiber modules within the back. And at present i’ll be doing Multimode. These are the series 2, considering they’ve interchangeable adapters on them. That’s what is going on to allow me to do a one jumper reference. I’ve already transformed the average connector that comes with this, which is SC, to LC, and i have done that on the far flung unit already. With a view to do a one jumper reference, we have to be utilising hybrid test reference cords, or TRCs. They’re hybrid in view that at one finish we’ve got duplex LC, that makes sense we’re testing duplex LC at present, the opposite finish slightly bit strange. We now have LC but we even have an FC connector with this crimson factor on it which is referred to as a mandrel. And it’s important that you just use a mandrel or else your readings are going to be pessimistic.The best way this works is we take our crimson SC connector and fasten it to the output port on the primary unit. Then, no longer by way of a bulkhead adapter, i’ll connect it immediately to the enter port on the faraway unit and due to the fact this is LC now, i will be able to do that. I’ve a 50-50 chance of getting this right. Which this sort of is it going to be? Good, these are Fluke TRC’s, and the way this works is pink is hot, black is cold.Our output is scorching, our input is cold. So that tells me i’m going to join my black LC to the far flung unit. I am then going to seize my other scan reference wire and do the equal in the opposite course. So, with my mandrel hooked up, i’ll take my SC, join it to the output port on the remote unit, after which take my black, which is cold, and fasten it to the input port. And you hear that chirp. Now I should say at this stage is, you’ll observe on the table right here, I’ve received a entire bunch of cleansing and inspection gear. I’ve already inspected and cleaned these test reference cords with out the inspection gear and without the correct cleaning gear this is not going to be very safe for you. You want inspection apparatus. Alright, so, let’s speak about constructing the DTX CableAnalyzer. I will rotate the dial to ‘setup’, and with fiberglass highlighted i’ll hit the ENTER key.My experiment limit is presently set to TIA. If I desired to vary that to ISO i’d hit the ENTER key, f1 ‘extra’, and go down to ISO where I see the 14763-three commonplace. My fiber sort is presently chosen as OM2, now that is an drawback, seeing that i’m trying out OM3 today. I have got to trade that to OM3. Why is that foremost? On the backside of your LinkWare experiment record you are going to see a list of supported applications. That list goes to be stylish upon this fiber form selected here. If i’d left it as OM2, any links larger than 82 meters, 10G base SR, would now not exhibit up at the backside.So that is an essential surroundings. I’ve received remote end Setup. I’m in clever far off mode, in order that stays. I’ve bought bi-directional checking out, and that’s presently chosen at no. Neither the TIA or ISO requires that, nevertheless, your patron advisor could require this, so please determine with them first. Then we are going to go throughout to tab quantity 2, where we see the quantity of adapters. This is an foremost environment, due to the fact that is going to influence your scan limit. It can be set to 2 for the reason that the link i’m checking out in these days is a simple patch panel to a patch panel. So i have a bulkhead adapter at one finish and a bulkhead adapter on the different end. Two adapters. And due to the fact i am now not atmosphere a reference by way of a bulkhead adapter, then my adapter depend goes to be 2. My reminiscence splices is zero, despite the fact that i am making use of mechanical connectors today. And once I say mechanical connectors, i am talking about forms such as the UniCam, which have a mechanical splice inside of.That is part of the connector, you don’t add a different splice rely in there for every of these connectors. My connector form is LC, that’s now not going to impact the final result of the experiment influence. That’s simply going to have an effect on the support screens on the DTX CableAnalyzer. And then I’ve additionally obtained my scan process. It’s set to one jumper, given that i am jumping from the predominant to the far flung unit in a single hop. I’m no longer going via a bulkhead adapter. And in the end, on quantity three, I’ve acquired my index of refraction. That is going to affect the length mentioned with the aid of the DTX CableAnalyzer. So it’s important to go to the vendor’s website, download the modern day datasheet, and be certain you’ve gotten the right values in right here.K, let’s set a reference. I’ll rotate the dial to ‘targeted functions’, and we ‘Set Reference’ highlighted. I’ll hit the ENTER key, and it’s going to draw a snapshot of my setup that I’ve just accomplished. So, I’ve allowed my sources to stabilize, and this is very important. You need to permit them to heat up, and that can take 5 minutes. It could actually take longer relying on how cold your items are very first thing within the morning. So, hit the scan key, and what it is going to do now is it’ll zero out any losses on the output connector and those experiment reference cords connected between the principal and the remote unit. And it’s going to come again with some loss values. And, as a guide, if it can be 50 micron, we would like this better than -24 1/2 dBM. If it can be 62 half micron, we would like it higher than -20 dBM, and if it’s better- if it is 9 micron, we wish it better than -8 dBM.That does not imply to say that our scan reference cords are in excellent situation, we will be doing a determine just a little bit later on to make certain they are in excellent condition. So, the whole lot looks fine there. I’m going to hit the f2, ‘ok’ key. I have the choice here of placing the size of the cords that i’m using for checking out at present. Again, that’s no longer going to affect the effect of the test outcomes, however it’ll show up on your LinkWare report to your computer. So i will press f2, ‘adequate’. Now, this is a very predominant step that many folks pass over. We need to be certain the sources are stabilized. So we’ll rotate the dial to ‘auto scan’, and hit the experiment key. If the sources have stabilized, my loss studying here must be zero dB for each fiber direction. So i am going to ignore the pass within the high proper-hand nook there, and look at the loss reading on the input fiber. That’s the input port on the important unit right here.And it’s displaying zero and zero dB. I don’t care about limit or margin, I simply want to ensure it’s zero, in order that tells me my source on my faraway unit is now stabilized. I’ll go all the way down to my output fiber on the most important unit here, and that’s additionally showing 0 and 0 dB. So, good, i do know they’re stabilized. On to the next move.Ok, so now that I set a reference, on to the subsequent stage. We’ll cast off the scan reference twine from the input on the important unit. And i will put a protecting cap on it. I don’t wish to harm it. I’m also going to dispose of it from the enter port on the far off unit. And, again, i will put my protective cap on there, to make certain it doesn’t get broken. The next move i’m going to do is on the major unit here, on the same end the place the mandrel is I’ve now got this LC. That is going to get plugged into the input port on the primary unit. After which i’ll do the equal on the faraway unit here. So, on the far flung unit now, i am provided with duplex LC, and, on the most important unit, i’m additionally provided with LC duplex.So this plugs into the patch panel at one end, this plugs into the patch panel at the different end and that i would go off and do a test. The situation is we don’t honestly know the way excellent these cords are. So, earlier than you try this, Take an LC bulkhead adapter and connect the important and far off items collectively. Of course, purple goes to black, and black goes to crimson. And, once more, If I’ve completed this right i will hear a chirp. Then what i’ll do is i’ll run an auto test to see what the loss is, right here. And i would like this to be higher than 0.1 dB if viable. Let’s do that now.Okay, so let’s run an auto test. And my enter fiber, which is my fibert going to the most important unit right here, has a lack of 0.09 and zero.10 which is best. And my other fiber has a lack of zero.09 and nil.04, So i do know my test reference cords are in excellent . Now, what you would do at this stage is ask the technician to avoid wasting these outcome as TRC 1 and TRC 2, for illustration. And then you could have documented proof that your experiment reference cords had been in good condition while you did the size.Now that we have now verified our test reference cords, we begin starting to make the measurements. So, very important, mainly if you are on a constructing website online, is once we disconnect our connectors within the core of that bulkhead adapter, we cap the fibers. Due to the fact that the final thing we wish these to occur to them is for them to get damaged. Take this off to at least one end, take this off to the opposite finish, and begin trying out. And that is how you installed successfully for an LC to LC duplex hyperlink, checking out utilising a one jumper reference.
