3.0 OPERATION METHOD
Four indicators on the front panel show which light path is being used. Inputs are
represented by A and B respectively, where A is the main input and B is the backup
input. The main and standby optical paths are automatically switched:
The user can set the Optic Switch Point. This value on the primary input (input A) may
be set between +10 dBm and -10 dBm. Once this is set, the unit will automatically
switch to the secondary (input B) if this value falls below the setting. For example, if the
Optic Switch Point value is set to -3 dBm, the unit will switch to the secondary if the
optical power of input A falls below -3 dBm.
* If optical signal powers are both less than switch point power, the device will maintain
the current state.
