I can't understand what mean " Reflation-60 dB " (SCA)
I would like to understand what is the typically guarantee a minimum reflectance of -60 (dB) in case i take a look in data sheet of connector SC/A
It mean that i will get a minimum light back from line back to Source? (only -61dB or less ) if yes it's kind of filter . For example lets say that i send -10 (dB) leaser power and i have a small air gap and reflation, it's meaning that i have less "light power" in the end of line and that's all, Am I right?
What happens if the transitive source will get the rarefaction?

Are you talking about Reflection rather than Reflation? I am not aware of term Reflation.
Reflection, when talking fiber, is the amount of the signal in DBs that is reflected back to the sender. This is not good as it can obviously reduce signal strength and can burn up equipment.
Perfect or no reflection is a solid fiber cable with no breaks. Any 'connection' used will have a certain amount of Reflection or signal loss. This depends on the type of connection and how well it is made whether it is made in the factory or in the field. Connectors from the factory are rated with a given amount of loss in their specs. ie: -60DB reflectivity using your example. Better connectors have lower ratings.
I am not a authority on this topic as I am trying to get up to speed myself. If this answer is not what you were looking for than I need to read a bunch more.... on Reflation.....

When the optical light reaches that connector the reflected signal will be 60dB below the level which reached the connector. So just for example sake if the signal was 0dBm when it hit the connector then the reflected signal would be 60dB below 0dBm, or -60dBm which is a very very low level.
Remember that every -3dB of change is half the original power level.
