Description
Enables or disables amplifier
operation; that is, turns the laser on or
off.
Enables or disables the "RF input low"
alarm.
Turns automatic gain control on or
off.
Sets the relative RF drive level into
the transmitter. Only effective when
AGC is off (manual gain control). This
is used in conjunction with OMI set.
Values from -2 dB to +2 dB allow
OMI set to be adjusted and maintain
specified performance
Sets the optical modulation index
level. Only effective when AGC is on.
NOTE: When the AGC control is in
the "on" state, the composite OMI can
be changed from the factory-preset
level. If the RF input power is 0dB
relative to nominal, the range is [-5,
+1] dB. If the RF input power is less
than 0 dB relative to nominal, the
maximum OMI set value is 4 dB + RF
Input Level.
Sets the nominal link distance for
optimum performance.
Turns Dither on or off. Dither may
need to be turned off for high drive
levels or channel loads in order to
improve performance.
