WebA good method is to select an OTDR empirical whose dynamic range is 5 to 8dB higher than the maximum loss you will find. For example, a single mode OTDR with a dynamic range of 35dB has a useable dynamic range of about 30 dB. Assuming a normal fiber attenuation of 0.20dB/km at 1550nm and splices every 2km (0.1dB loss per splice), a … WebMU909014C/14C6/15C/15C6.
