As a network operator, obtaining highly accurate link loss measurements and knowing whether a traditional light source power meter (LSPM) or optical time-domain reflectometer (OTDR) is best to characterize fiber links is very important.
Looking for best practices to mitigate the degree of measurement uncertainty in each device?
