Fiber-optic communication network has stepped into a new era of 100Gbit/s(or above)systems and strides rapidly toward the rate of 400Gbit/s/1Tbit/s systems.Currently
in most 400Gbit/s/1Tbit/s tests
the feasible Optical OFDM(OOFDM)-based high-rate transmission schemes include the Coherent Optical OFDM(CO-OFDM)
All-Optical OFDM(AOOFDM)and hybrid electro-optical OFDM.This paper comparatively analyzes the transmitter and receiver structures of the above mentioned three types of systems and summarizes their performance advantages and disadvantages in high-rate fiber-optic transmissions and the focal point in the next step researches.
