Exercise 10

A soliton transmission system operates at 1550 nm with fibers that have a dispersion of 1.5 ps/(nm · km) and an effective core area of 50 m 2. Find the peak power required for fundamental solitons that have a 16-ps FWHM width. Use the value n 2 = 2.6 × 10 -16 cm 2 /W. What are the dispersion length and the soliton period What is the required peak power for 30-ps pulses
