Orthogonality division multiplexing(OFDM) is widely adopted in many RF-wireless communication systems such as LTE ,WIMAX etc.In optical communication,This method of multiplexing is demonstrated many times. But according to my knowledge still OFDM is not used in available optical networks.
I want to know are there any optical communication networks that use OFDM?.
If not what are the practical issues encountered with the implementation?.
Dear Nuwan,
May be OFDM is used in visible light communications VLC. The performance parameters of the system show there is no obstacles for applying the OFDM modulation scheme on such communication systems.
I would like that you see the paper in the link: Article Enhancing the performance of optical VLC system based on asy...

Dear Nuwan,
Kindly, you can read this book:
Z. Ghassemlooy, L. N. Alves, S. Zvanovec, and M.-A. Khalighi, Visible Light Communications: Theory and Applications. CRC Press, 2017.
I would like to share also a new paper related to MIMO OFDM in VLC:
Conference Paper Adaptive Unipolar MIMO-OFDM for Visible Light Communications
I think OFDM consider a complex technique for optical wireless communication system and give a low quality factor and high BER compare with PPM and OOk.
