    When I was procrastinating today, I was thinking on how I should plan my ODM (Optical Distribution Network). Doing a cascading style using FBT makes the most sense. Bali split lang with uneven ratio, then extend as needed. Gusto ko rin ma-maximize yung 128 ONU per PON nung OLT ko. One thing na hindi ko…

    I bought a 9 dBm EPON OLT PX20++++ module for backup (in case one of my EPON module fails) and experiment (I’m curious if the additional dBm have significant effect to the signal). I bought it for PHP 1460.00. Curious kasi ako how much difference 2 dBm makes it terms of signal strength. Ang default…

    After all testing things out and making sure it works, nag-go ahead na ko and install my first NAP sa bahay ng Tita ko. Nakalatag na yung fiber cable from my office to their house, kailangan ko na lang terminate at install ang NAP box and client modem. From my office, ang fiber cable na…

    For a couple of weeks now, I’ve been considering buying an OLT. What kept me from biting the bullet is the return of investment. It doesn’t make sense to pursue, ROI-wise. I can earn much more if I spend my time on something else like AWS certifications. When I changed my view from it being…
