Hi Jyoti,
First i accept your thanks in advance.
I was discussing that using number of loops for fiber is not equivalent to its equivalent fiber size in terms of BER and Q-factor, but i think not very much difference occurs. It is because when we multiply size of SMF and DCF we have to change its parameters. But when we use no. of loops , its configuration remains unchanged and hence we get different results. for more explanation i am attaching osd file in which we use symmetrical compensation techniques (DCF+SMF+DCF)….. IF WE change the the length of fiber (DCF, SMF) independently change the length of fiber, we have to change its internal parameters but when change the no of loops the length of fiber increases without changing the internal parameters.
