Dear sir Ahmad and D.Kakati
I have an important query,Please address
All the x-couplers in optisystem give 3dB insertion loss.But there are many vendors provide state of the art couplers having minimum loss as 0.5dB when the coupling ratio is 50:50.whats your view in this regard to use 0.5dB instead of default 3dB in optisystem?I am attaching the data sheet of a vendor.Please comment
