    It would be great if you can select to have only a 2 point loss. You basically can have that, but the text you read for capital A and capital B is very small unlike the large bold 4 point text. Any time I have every suggested useful thinsg for technicians, you don't listen.

    Question regarding the graph. I understand the bottom of the graph represents the footages. What does the left side represent?

    Hi Kevin, Thank you for your videos.. for the 4 point marker.. does it only be set for the 1550 or both 1310 and 1550. My range is usually no longer than 1000ft. Thanks

    Yes when measuring in real time you can only send one wavelength. Start with 1550 if it passes than 1310 should be fine. It will have higher loss but that is expected. If 1550 looks bad than check 1310 if 1310 is better you have a fiber management issue. You can toggle back and forth between 1410 and 1550 but keep in mind 1310 may require a longer pulse width to accommodate extra loss.

    Hello, thanks for the video, I have just 1 question. Could you please explain why is the 4-Point event loss BEFORE cleaning lower than AFTER cleaning? With clean connector, I would expect lower loss and also lower reflectance...

    Great question and a super simple answer. I did not take enough care to clean the connection. I used a one click and I did not really take much care. Ideally I would take my time, inspect and clean but for this training it was not important enough to add extra time to the video which resulted in not the most ideal cleaning.

    Hi Kevin, great video! So, this method is just to confirm if both reflective/non reflective event is a macro bend or a connector/splice. Am I right

Si je peux avoir une traduction des deux vidéo en français,je serais le technicien le plus heureux grâce à vous. Merci beaucoup et continuer ainsi

    How to define a good reflection index? And what happen when reflection is so low or so high? Thanks !

  • @KevinPeres

    @KevinPeres

    If you are talking about Reflection from a connector typically see -45 to -50dB as acceptable Pass-Fail values. UPC connectors are -50 to -55dB at spec and APC -65dB or better. We start to see issues if we are worse than -40dB and if there is amplification of the signal it can be compounded.

    I will take a look at the video again. Setup is a big part of understanding optimizing 4 point measurement in real time. May be I can streamline that section a little more. I catered it to techs like myself at the time who worked in very restricted circumstances that required quick analysis.
