General Information: Location A Location B

This OTDR report summarizes a fiber optic cable test between locations A and B that failed. Key details include: - The span length was 0.4651 km with an average loss of 1.162 dB/km and total span loss of 0.541 dB. - The average splice loss was 0.164 dB and maximum splice loss was 0.189 dB. - There was a non-reflective event at 0.2696 km with a loss of 0.139 dB and another at 0.4186 km with a loss of 0.189 dB. - The test failed due to the span loss exceeding the 20 dB threshold.
