Hi, friend. I have a team OTDR JDSU MTS 2000Apparently the SC optical port is damaged. Due to poor "cleaning" practices. Apparently the connector ferrule is scratched, which causes very poor contact and obviously completely erroneous measurements. Is there an easy way to replace it?
The connector can be replaced, I got a $1300 quote from Viavi for one of my modules. I would like to see the connector if you have a scope, as well as a shot so I can see the launch conditions. Another reason for bad measurements could be the adapter, especially the swapable adapters. If these get damaged, the connector doesn't remain seated, causing errors in the shot.
Wow! What a really nice comment. I greatly appreciate it, and I will keep making the videos. Let us know if there is a topic you would like covered. Thanks again.
Per the International Electro Technical Commission (IEC) standards body states IPA should not be used on connectors because it can contaminate them and cause degraded performance due the hygroscopic characteristics. An open bottle of IPA will lose 7% of it's purity in 15 minutes. So IF you are having high loss splices, I would look at the entire preparation process. As I say, this MAY be a contributor. Thanks for the comment.
If you never get a bubble in your splices, then that's win. From the folks at Chemtronics "The hygroscopic nature of IPA is very pronounced. IPA exposed to the air will absorb moisture rapidly until it reaches an equilibrium value of 65% IPA to 35% water."
Awesome, thank you I’m a fiber tech here in Arizona learning pond stuff sometimes testing can get a little irritating and I really appreciate the video. Thank you you subscribed.
Was it 7 miles or Kilometers? I have seen some VFLs where under magnification you can see a faint dot, it wouldnt be usable in the field though. I would be interested in knowing the brand/link of the one you have. Thanks for the comment.
@@VanTekConsulting It was 7 miles(11.2 kilometers) Brand is (Karvinger - Rechargeable Visual Fault Locator 30mW 18miles) and I used another which and got 5 miles(8 Kilometers) Brand Sysotek Visual Fault Locator - Rechargeable VFL Fiber Optic Red Light - Retractable Head fits SC FC ST.
@@VanTekConsulting Ough, I can barely handle the anxiety of interacting with other humans, let alone the anxiety of fouling potentially hours of work, if not potentially days worth under specialized enough circumstances. Handling my Oculus data cable makes me nervous and that's literal childs play compared to this stuff. Whew.
Thanks for the question. There are kits sold, but I have found that they usually have many items I don't want or need. It's best to source these separately to get exactly what fits your personal requirements.
Thank you. Testing you own ONT is not really necessary after installation unless it is completely dropping offline, then it would be up to the provider to rectify the issue. It's more the case of you have light or not. You also run the risk of contaminating a connector with dirt which would cause an issue. That said, if you know what wavelengths are on your PON, it would be possible, but not advisable for an end user to use this type of meter. Just to be clear, the power level of the light does not equate to lower latency, higher speeds, more bandwidth, etc. Hope this helps.
No, but all the event locations will be incorrect. Loss is calculated using the backscatter level at the beginning and end of an event. Thank you for the comment.
i have a question about the connector’s definition. 0.5db per connector means , eg. 1 Fc connecting to an adaptor and adaptor connecting to another fc connector. Or there are 2 connectors loss, total 1db loss. Thank you! I am new to OTDR.
The application specific meter to test xPON would be the correct meter to use. These range in price based on brand, options, location, etc. and are a typically a few thousand dollars. I that is not in the budget, then you could use a standard power meter understanding there may be a bit of variance that needs to be corrected or allowed for. This option is better than not taking any measurement in my opinion. Hope this helps, thank for the question.
FANTASTIC video. i've been in the field several years and always appreciate ways to learn new/better methods. I bought the same fusion splicer a few years ago and learned by youtube videos. I only emergency ISP sliced in the field as needed, but overseeing longhaul sites, its been incredibly handy to have in a pinch!
Thanks for your interest. If you would like to order some of these just use our "Contact Us" form (link in the video description). We will follow up with you via email.
Thanks for the question. Actual calibration needs to be done by the factory, When measuring in dB (which is a relative value) you can tap the REF button to zero out, or set your reference level to Zero. Example, if you are measuring in dBm your transmitter power level is -10 dBm (absolute value), and your receive level is -15 dBm (absolute value), your loss is 5 dB (relative value between the two absolutes). Alternatively, you could measure in dB, at the transmitter and "Zero" the meter by taping REF (telling the meter that -10 dBm is zero). When you measure at the receiver, the meter would read -5 dB. Using the dB measurement saves you from doing the math, but IF you forget to redo the reference on the next measurement, it will skew your results. Hope this helps.
@@VanTekConsulting Thanks for replying! Yes, I've already done that, but I have another Veex powermeter and an Anritsu otdr that have the measurement calibrated and the same, the OLP-38 is measuring 1dbm above and I wanted to make them all the same.
@@MAMTECNOLOGIA If you are saying that the VeEx and the Anritsu (I assume you are using the PM function on the OTDR, or are you shooting a known fiber?) are measuring the same, one possibility is that the connector on the OLP-38 is damaged. Do you have a probe to look at that? I'm not sure of your test bed / process, light source, connectors, etc.. Feel free to give us a ring if you want to talk through this.
@@VanTekConsulting I bought this month a light source an orientek T15M in your description this output is -5Db, it is for this equipment that I am checking the readings
Thanks for noting that. If you are interested in getting some of these, you can visit our "Tech Shop" vantekconsulting.net/shop/. eBay shipping was more than what we charge for the cover, so we stopped listing. I missed the link change.
Switched contracting companies and after showing someone how we'd stratasync the meter is locked. Can doing this with USB unlock it? Assuming the administrator for previous company locked it when synced. I purchased it used.
There is an option in Stratasync to lockdown meters on connect if they are lost or stolen. If this is your meter and the last company had it associated with their account, then enabled the feature, it is possible that it got locked. The only way I know of is to contact them and have them release the meter from their account. Hope this helps.
I remember finding your videos when I started at JDSU back in 2014. Thanks for putting them out there! We are known as Viavi now, but we do have a new higher powered VFL now - the FFL-105 - 5mW. Keeps it in the eye safety range for laser (class 3R) and gives a boost to the power, should be helpful around those PON cabinets for quick bend checks! Reminder to techs to check your launch cables with this too, been in the field too many times and have seen bad OTDR connections error messages, most of the time due to a microbend around jumper connectors (sometimes you'll microbend / break by accidentally closing lid on the jumper) or a gunked up OTDR port.
Hey Ryan. Thanks, for the update on the Viavi 5mW VFL. For those who would like more info visit www.viavisolutions.com/en-us/literature/ffl-050-100-visual-fault-locators-data-sheets-en.pdf
Hello. excellent video. Do you know how I can install the RFL module in this equipment? ONX-580. in the software options menu the "resistive fault locator" module has the word "upgradeable". How can I get this module to be "enabled" "enabled" Thank you very much I have already updated the SWbundle to version 10.4.10 and the RFL module did not activate.
Thank you, RFL is a licensed option, to enable the option contact your Viavi rep and they can help you with the upgrade. The 10.4.10 is a firmware update adding more "Upgradeable" options and enhancing current licensed functions.
Thanks for the video, do you know of any way to enable all software options without going to viavi? As they charge a fortune. I have never seen all enables like it shows on your onx-580
Licenses are pushed via StrataSync when you purchase them. Or they are sent to you via USB drive. Either way, you cannot enable these options without having root access, or paying for them.
Thanks for watching. As #TMGCommunications states, all of these are paid upgrades. Keep in mind that not all users require all functions so it's an "Ala Carte" type of licensing. This is also a training meter, so typically you wouldn't see all of these functions enabled (or used) in a field meter. Even in training I only use a few of the functions (guessing maybe 30%?). As a note, if you buy used equipment, you always want to ask for a screen shot of the licensing. Just because a device is "Capable" doesn't mean it is licensed to do it.
Agreed, I am based in Arizona so very familiar with a dusty environment. A lot of the splicers I deal with and train are "Tailgate" (no trailer) so it is even more important to keep up with the maintenance on the machine. Thanks for the feedback and the suggestion.
