Orthogonal frequency division multiplexing (OFDM) is a modulation technique which is now used in most new and emerging broadband wired and wireless communication systems, because it is an effective solution to intersymbol interference caused by a dispersive channel. Very recently a number of researches have shown that OFDM is also a promising technology for optical communications, though its application in real optical systems is still under study In this work, an optical OFDM transmission is simulated in a scenario created by means of Virtual Photonics Integrated (VPI) software, which allows the design of many configurations regarding optical communications. The programming of the OFDM coder and decoder has been done with Matlab software, and custom modules have been created in VPI to perform the functions implemented in the codes. Before that, the basic theoretical concepts of OFDM and the requirements implied by its adaptation to the optical field are explained, along with a brie
