Signal loss over fiber varies with distance and environment.
Signal loss over fiber varies with distance and environment.
you've made a great progress getting your FTTH setup ready. the signal attenuation of 15.5 db is quite low, indicating a strong and stable connection. the green connector you received is likely designed for your router, and connecting the patch cable properly will help maintain performance. the logarithmic values you saw online probably relate to how signal strength decreases over distance, but understanding it doesn't need to be complicated—just think of it as a measure of loss in decibels. with this setup, you should experience reliable internet speeds.
It indicates a difference of 15.5dB between transmitted and received light levels across the fiber. For instance, if the transmitter sends +5dBm at the ISP office, the receiver picks up -10dBm. This difference affects only signal quality, not speed or latency.
It's related to light reduction. In a passive optical network, around 15dB of loss is typical from splitter effects and distance. https://community.fs.com/blog/test-optic...ource.html Focus on the 1:32 ratio since that's common in FTTH/P setups.
