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 …
WebOTDR คืออะไร? OTDR stands for Optical Time Domain Reflectometer. It is a device for testing optical fibers. ... The higher the dynamic range, the wider the range of the OTDR. Inadequate dynamic range impairs the capacity to assess the entire link length as well as the accuracy of link loss, attenuation, and far-end connection loss WebSmartOTDR 100A B Series Data Sheet - VIAVI Solutions
