Check Light Levels on 7300 POS Interface

Is there a way to check the incoming light levels of SM fiber link to a POS interface on the router itself?

Not that I'm aware of. The card itself has the Carrier/Alarm LED that should be Green if/when a valid SONET signal is detected on the incoming line.

To measure the optical power level though, I believe you need to disconnect the fiber and use an Optical Power meter.

The higher end SONET cards (e.g, those used in the 15400 series) have built-in power signal level measurement but then you pay a lot more for those.
