What specific parameters can be checked using a GPON Tester?

A GPON (Gigabit Passive Optical Network) tester is used to check the quality and performance of fiber optic networks. Several important parameters can be tested with a GPON tester:
1. Optical Power Levels: The tester checks the strength of the light signal being transmitted and received in the fiber. This helps ensure the signal is strong enough for smooth data transmission.
2. Loss of Signal (LOS): This measures if there are any breaks or interruptions in the connection, which could cause data loss.
3. Optical Return Loss (ORL): This tests how much light is reflected back into the fiber. High reflection can affect the performance of the network.
4. Data Transmission Rates: The tester checks the speed at which data is transmitted between the central office and the end user, ensuring it meets the expected gigabit-speed standards.
5. Bit Error Rate (BER): It measures how many errors happen during data transmission. A high error rate means poor network quality.
6. Distance Measurement: The tester can measure the distance to the point where there is an issue, helping technicians locate faults in the network.
