Introducing the PPM-350C PON Power Meter 4
Typical Applications
You can use your PON Power Meter in two modes:

FTTx mode: You can use your PPM-350C PON Power Meter during service
activation (at ONT) or to troubleshoot passive optical networks (at ONT, drop
terminal, fiber distribution hub or CO). This mode allows you to measure two or
three wavelengths simultaneously, depending on the configuration of the unit.

OPM mode: You can use your PPM-350C PON Power Meter to measure the
output power (in dBm) or loss (in dB) using one of the unit’s 40 CWDM
wavelengths available. This mode allows you to measure networks or devices
carrying only one wavelength.
