4.2.1. Displaying the Optical Power
The 7707OO-HD module can measure and display the input optical power over a range of 0dBm to
-40dBm at 1dBm increments. The 7707OO-HD-H module can measure and display the input optical
power over a range of -7dBm to -40dBm at 1dBm increments. To display the Input Optical Power press
the pushbutton one or more times until the PWR message is shown on the display. After one second the
detected input optical power will be shown (in units of dBm).
Indicates optical input powers exceeding -1dBm for 7707OO-HD and optical input
OVR
powers exceeding –7dBm for 7707OO-HD-H.
Optical input power within this range for 7707OO-HD.
-1 to –40
Optical input power within this range for 7707OO-HD-H.
-7 to –40
Optical input power below –40 dBm.
LOW
Indicates that no valid input signal is present.
LOS
4.2.2. Displaying the Video Standard
When the reclocker is enabled, the 7707OO-HD detects the Video standards of the signal present at its
optical input. To display the Video Standard press the pushbutton one or more times until the STD
message is shown on the display. After one second the detected video standard will be shown. The
following list describes possible displays and their meaning:
SMPTE 259M-A, 143 Mb/s 4Fsc Composite NTSC
N143
SMPTE 259M-B, 177 Mb/s 4Fsc Composite PAL
P177
SMPTE 259M-C, 270 Mb/s 4:2:2 Component 525 line, 4:3
N270
SMPTE 259M-C, 270 Mb/s 4:2:2 Component 625 line, 4:3
P270
SMPTE 259M-D, 360 Mb/s 4:2:2 Component 525 line, 16:9
N360
SMPTE 259M-D, 360 Mb/s 4:2:2 Component 625 line, 16:9
P360
SMPTE 344M, 540 Mb/s 4:4:4 Component 525 line 4:3
N540
SMPTE 344M, 540 Mb/s 4:4:4 Component 625 line 4:3
P540
SMPTE 292M, 1.485 Gb/s
HD
310M
SMPTE 310M, 19.4 Mb/s
Indicates the reclocker is in non-reclock mode.
BYP
Indicates that no valid input signal is present.
LOS
4.2.3. Displaying the EDH Errors
For SD rates, EDH errors are displayed in a different manner than optical power, and video standards.
When EDH error detection is enabled, the display of EDH errors will take precedence, and overwrite the
existing indication with the message EDH. The EDH error display shows if any EDH errors have occurred
during the previous 1 second interval. If the EDH errors are continuous, then the display will alternate
between the EDH display and the selected video standard or equalization displays, allowing both to be
monitored.
To enable the EDH error display, press and hold the pushbutton until the EDH DISABLE LED goes OFF.
To disable the EDH error display, press and hold the pushbutton until the EDH DISABLED LED turns ON.
The EDH error display can only be enabled when there is a SMPTE 259M or SMPTE 344M input signal.
