In this case use an optical power meter (OPM) and test the input port of the splitter for the optical power level (dBm) from the OLT at 1490 nm. Optical splitters in the outside plant (OSP) are used mostly in passive optical networks (PONs) for fiber-to-the-user (FTTx) networks, and are often overlooked as failure points. First, attach a launch reference cable to the optical light source of the proper wavelength (some splitters are wavelength dependent), and then calibrate the output of the launch reference cable with the optical power meter.
