What has just been said refers, of course, to traditional structured optical cabling infrastructures, where the final application uses a pair of fibers for each link. The new generation optical networks of the xPON ( Passive Optical Network ) or POL ( Passive Optical LAN ) type, on the other hand, must be verified with different measurement methods and above all with the complete verification of the channel performance, which must be performed with an instrument Next generation OTDR prepared with an analysis software able to discriminate the different branches present downstream of the splitters . Also for this interesting topic we refer our readers to future publications.
