ITU Frequency Adjustments for DWDM Applications (***)
The OT-1000-HH offers the option to tune the optical frequency (wavelength) of the transmitter by ±100 GHz
in steps of 50 GHz. This option may be helpful in DWDM applications. For example, it can be used to reduce
the number of spare transmitters by not keeping all used wavelengths in stock. The tuning can be performed
via an OT-NEC-A (network element controller).
Return Application Adjustment (***)
The OT-1000-HH transmitter can be used for return applications. Since AGC will not work for intermittent
return path signal characteristics, the transmitter must be set in AGC-Off mode for return applications!
Moreover, the alarms and warnings for OMI and RF Input Power should be masked! Due to the intermittent
character of return path signals, the transmitter will generate OMI and/or RF Input Power alarms and warn-
ings, but this condition is OK for return path application.
Redundancy Applications (Optical Power On /Off) (***)
The transmitter can be configured as a back-up transmitter with optical output power off in redundancy ap-
plications (standby mode). The standby mode allows turning on the transmitter within less than 10 seconds.
Therefore, situations where a fast switching to a redundant transmitter is requested can be implemented by
using standby mode.
The optical power on/off switching can be performed via an OT-NEC-A (network element controller).
Software Setup (***)
The detailed settings of the OT-1000-HH are performed using an OT-NEC-A network element controller.
