dBm App

[English Version] In many situations, a new ONU is installed even when optical power levels fall outside the optimal range for a high-quality connection. This often leads to poor network performance and customer dissatisfaction.

Although there are many differences in materials and technologies used in fiber optic networks, optical power calculation is a key ally in technical management. It allows technicians to mathematically estimate the expected performance based on signal diffraction and attenuation along the fiber path.

Attenuations caused by splices, connectors, and cabling introduce imbalances in PON networks, directly impacting signal integrity between the OLT and ONU. Understanding this imbalance is crucial for preventive maintenance and ensuring service quality before offering internet access to customers.

The optical power level measured at the service point during installation is a strong indicator of the potential performance and reliability of that customer's connection. Tools like the Power Meter, when correctly interpreted, are essential for proper network qualification.

The dBm App was designed to interpret Power Meter readings and provide practical, reliable estimates to guide technicians before activating a new fiber line.

Key features include:

Estimation of maximum download/upload capacity

Calculation of safe installation distance (it’s not simply “up to 20km”)

Analysis of signal imbalance caused by attenuation

Compatible with GPON, EPON, XGPON, and GEPON networks.

[Portuguese version] In many cases, the installation of a new ONU is carried out even outside the ideal parameters that define a quality installation. This can compromise network performance and end customer satisfaction.

Despite the variety of materials and technologies involved in the construction of optical networks, the calculation of optical power is an essential tool in technical management, allowing for the accurate estimation of the performance that the network can offer based on diffraction and losses along the optical path.

Attenuation introduced by splices, connectors, and cables causes imbalances in the PON network, directly affecting the integrity of the signal between the OLT and the ONU. Knowing this imbalance is essential to anticipate failures and avoid activating services under critical conditions.

The optical power measured at the point of service, at the time of installation, indicates the quality of the line and the operational limits of that customer's connection. Tools such as the Power Meter, when correctly interpreted, become essential for technically qualifying the network.

The dBm App was developed precisely to interpret the values ​​measured by the Power Meter, offering practical and reliable estimates to guide the technician before activating a new optical line.

The app's features include:

Estimation of maximum download and upload capacity

Calculation of safe installation distance (we know that it is not simply “up to 20km”)

Assessment of imbalance caused by attenuation

Compatible with GPON, EPON, XGPON and GEPON networks.
