A network technician is troubleshooting a fiber optic link that is performing below expected levels. The technician suspects that the issue may be related to the signal strength. What is the BEST method to verify and troubleshoot the signal strength related issues?
Adjust the wavelength settings on the networking hardware.
Check the compatibility of the transceiver with the installed fiber cables.
Measure the dB loss using an Optical Power Meter.
Replace the fiber cables with higher category ones to improve signal strength.
