From the MAIN or SCROLL menus on the ICIM, navigate to the Prisma II Optical
Switch MODULE menu. From the MODULE menu, press the
STA T
key to display
the STATUS menu.
The following table describes each switch status parameter.
Parameter Units Meaning Typical Value
SwPos N/A Switch position. Bar
PwrIn3 dBm Optical input power on port 3. 0.0 dBm
PwrIn4 dBm Optical input power on port 4. 0.0 dBm
ModTemp °C Module temperature. +25.0°C
SwTemp °C Switch temperature. +25.0°C
Cross N/A Cross position control False (always)
Bar N/A Bar position control False (always)
Mode N/A Auto or manual mode Auto
WaveLen nm Wavelength of optical input for both inputs. 1550 nm
NomPIn3 dBm Nominal input power at port 3. 0.0 dBm
NomPIn4 dBm Nominal input power at port 4. 0.0 dBm
Delta dB
The value relative to nominal below which the input optical
power must fall for the switch to operate (auto mode only).
6.0 dB
HystAmpl dB
Hysteresis amplitude: The value above which the input
optical power must rise for the switch to begin the hysteresis
timer.
3.0 dB
HystTime Second
Hysteresis Time: Length of time that primary optical power
must remain above the restore threshold before the switch
will revert to the primary position. Only applies if Revert is
True.
1.0 second
Revert N/A
Allows switch to revert to the primary position after optical
position is restored.
