Fiber Optic Cable Bidirectional Test Formula

At a splice between Fiber A (with backscatter coefficient X) and Fiber B (with coefficient Y), the OTDR sees two effects: the actual splice loss (call it L) and the difference between X and Y. As the name implies, bidirectional OTDR testing is a method of. A b...
