Very informative video and other videos also. I am small isp in my area, now shifting from epon gpon due to large customer base. Purchased syrotech olt. I per my knowledge and by your before video, I need to put ont/onu between -17 to -22. We can achieve this by 1/8 primary splitter (-7 to -10) then 1/16 secondary splitter (-17 to -22) for end user. . But for my case, my current network is on single core design, we use couplers + splitters. My doubt is what will be drawback of 95/5 coupler than 1/8 splitter, which gives same power on same location. After 95/5, i use 1/16 splitter. Is this ok if customer have -17 to -22 power ?
