To place a Optical PON Power Meter in the link, as above:
As the system is turned on, the downstream 1490nm (& 1550nm if applicable) and upstream 1310nm power reading will appear on the screen.
The two optical ports (SC/APC) are physically connected in the optical link during testing.
To avoid wearing out the two PON power meter optical connectors, it is highly recommended to use two sacrificial patchcords (SC/APC to SC/APC), to be connected to the PON meter at all time.
