      Well it actually depends upon the Bandwidth allocation Anita. You have to check the B.W and then try to figure the loss in db/km and you can get the desired length.

      According to theory and ITU-T recommendations, you need to astimate OSNR at the receiver based on attenuation in your fibers (which should be compenstaed by EDFA) and noise produced by EDFA

      Additionally, you should consider that EDFA can launch high power into the fiber which might generate non-linear effects. In the end, the maximum reach in km is a trade-off between launch power and noise.
