Next-Generation FTTH Passive Optical Networks : Research Towards Unlimited Bandwidth Access

Dense FTTH Passive Optical Networks (PONs) is a cost efficient way to build fibre access, and international standards (G/E-PON) have been already launched, leading to new set of telecom products for mass deployment. However, these systems only make use of less than 1% of the optical bandwidth; thus, relevant research is taking place to maximize the capacity of these systems, with the latest opto-electronic technologies, demonstrating that the huge bandwidth available through the fibre access can be exploited in a cost efficient and reliable manner.
