What is it about?
The signal in one wavelength can be converted to any wavelength in a wide band, so the dynamic and capacity of the communication networks can be largely increased.

Why is it important?
If compare the transmission of a signal from A to B to a far trip from one place to another place, the wavelength just like the means of transport. In a convenient transit point, if the train is full, we do not need to wait a long time for the next train,and we can select to take a ship or a airplane. The flexible wavelength converser just like a convenient transit point.
Perspectives
The optical signals can be moved more flexibly and efficiently.
