These acronyms refer to an optical time domain reflectometer , for its acronym in English. It is an optical-electronic instrument that is professionally used to view cabling performance ,
display anomalies along the cable, and troubleshoot problems, should they appear. To be used reliably, it must be properly calibrated and certified by the manufacturer or authorized dealer .
To do this, the OTDR will measure a trace, which will serve to identify any anomaly that occurs and that has not been perceived in the level 1 measurements. For the latter, it is essential to carry out a complete certification of the fiber , since this can Access from the first moment to a complete verification of the installation, monitoring quality and maintenance
The techniques we use to carry out the fiber optic certifications are those tests that are carried out to measure that the optical cable in particular, and the installation in general, follow the regulations in this regard, according to industrial standards.
