Testing Optical Transmit Power :

Testing the optical transmit power of an ONU involves measuring the power output at its upstream port.

Key Considerations :

Wavelength : The upstream wavelength for GPON/XGS-PON is 1310 nm , so selecting this wavelength is correct.

Power Meter Type : A common power meter is not suitable for testing optical power in live networks. Instead, a specialized optical power meter or an OLT-based monitoring tool should be used.

Why FALSE?

Using a common power meter is incorrect because it may not provide accurate readings or could disrupt network operation.

Thus, the correct answer is B .
