FWM is a linear impairment that produces crosstalk four adjacent wavelengths are used.

FWM is a non-linear impairment that produces crosstalk at the sum and difference of two wavelengths.

FWM is a non-linear impairment resulting from varying velocities at different frequencies.

FWM is a linear impairment resulting from pulses broadening over ultra-long distances

Step 2(analyze Traffic Demand and Step 4 ( Define Network Topology)

Step (Define Network Architecture ) and Step 5( Evaluate Traffic Demand on Architecture)

Step2 (Analyze Available) and Step 8 (Analyze Cost).

The steps to be followed depended on the requirement of the network extension.
