Hi albaity,
As the effective area of the fundamental mode is a measure of the area over which the energy in the electric field is distributed.
This parameter is important for DWDM applications.
We know the effective area of a single mode optical fiber is obtained by this relation :

A eff= pi * W2( lambda )
Typical single-mode fibers, as used e.g. for optical fiber communications,
have effective mode areas of the order of 100 μm2.
Large mode area fibers have several times higher mode areas, sometimes even above 1000 μm2.
On the other hand, there are some photonic crystal fibers with mode areas below 10 μm2.

According to optiwave component library pdf file the effective area of fiber is chosen to 80 μm2.
And it is fixed defaukt value.
I think this value is best.

Seeking your response.
