Often the installation of a new ONU occurs even outside the estimated limits for what would be a quality installation.
There are many differences between the materials used in the construction of optical network devices, however the power calculation becomes an ally in customer management, mathematically estimating the performance that the calculated diffraction of the network can deliver.
The attenuations cause unbalance in the optical network, which will influence the integrity of the signal transmitted between OLT and ONU. The importance of knowing this imbalance lies in correctly estimating the need to repair the network before continuing to offer internet services.
The optical power of the service point, checked at the time of installation, denotes the performance and ranges that line will have when installing a new customer. The POWER METER, like every measuring instrument, needs to be interpreted to have functionality in its use, from the point of view of the qualification of the network.
dBm App is an application designed to interpret the value given with the POWER METER, offering important estimates to be considered before installing the new line.
for example:
-max capacity Download/Upload
-max distance for facilities (not 20km)
-imbalance caused by attenuations.
