BERT or bit error rate test is a testing method for that uses predetermined stress patterns consisting of a sequence of logical ones and zeros generated by a test pattern generator. A BERT typically consists of a test pattern generator and a receiver that can be set to the same pattern. They can be used in pairs, with one at either end of a transmission link, or singularly at one end with a at the remote end. BERTs are typically stand-alone specialised instruments, but can be.
To perform an OTDR test correctly, you must: 1. Set core parameters (Wavelength, Distance, Pulse Width); 4. Run the test (Real-time or Average); 5. An Optical Time Domain Reflectometer (OTDR) is the most powerful tool for characterizing fiber optic networks.
