160-Gb/s optical time division multiplexing and multicasting in parametric amplifiers

We report the generation of an optical time division multiplexed single data channel at 160 Gb/s using a one-pump fiber-optic parametric amplifier, and its subsequent multicasting. A two-pump fiber optic parametric amplifier was used to perform all-optical multicasting of 160 Gb/s channel to four data streams. New processing scheme combined the increase in signal extinction ratio and low-impairment multicasting using continuous-wave parametric pumps. Selective conjugation of 160 Gb/s was demonstrated for the first time.
