Singlemode Fiber Optic Power Monitors
Through software
*
, you can read the input and output power levels of the
singlemode fiber optic port on the access line cards with diagnostic capabilities.
Input Power Level
The accuracy of the input power monitor is
The accuracy of the input power monitor is
±
1 dBm from -28 dBm to -12 dBm.
The accuracy is
±
2 dBm from -31 dBm to -29 dBm. The monitor is
unresponsive below -31dBm. If there are no cables connected to the fiber port,
the software may display a reading of -40 dBm. The access line card peaks at -
12 dBm and reaches saturation at -7 dBm.
the software may display a reading of -40 dBm. The access line card peaks at -
12 dBm and reaches saturation at -7 dBm.
The singlemode long haul (R231-17) and extended long haul (R231-1J) ports
are operational down to -34 dBm, which is too low for the monitor to measure.
If the input power level is between -34 dBm and -29 dBm, a valid link will be
established, however, the light level displayed by the software will show a
reading of -40 dBm. This reading is not a failure indication; it simply means the
level is beyond the range of the power monitor.

Output Power Level
The accuracy of the output power monitor is
The accuracy of the output power monitor is
±
3dBm. Failure readings indicate
that the card is non-functional and must be replaced. If there are no cables
connected to the fiber port, the software may display readings that indicate
failure.
