Optical Orthogonal Frequency-Division Multiplexing, or oOFDM is the latest ADSL technology developed by Monash researchers mainly to improve the amount and speed of data transfer from the conventional copper and wireless networks.

As more and more people are using the internet, larger volume of data are being transferred from one virtual locations to another. Imagine, millions are using the internet every second, uploading and downloading media files like video. Stuffs like these can cause major challenges to the existing broadband infrastructures.

oOFDM offers an inexpensive means of dramatically increasing long-haul capacity from the current transmission rate of 10 Gigabits per second to more than 100 Gigabits per second, over new and existing optical fibre.”Standard data transmission is equivalent to transmitting a series of single notes, but oOFDM is more like transmitting the notes grouped together in a chord. Since more data is packed into the chord, more information can be sent that is less prone to technical issues, as each signal travels down the optical fibre”, Professor Lowery, Monash University.
