Scaling technique of triple play services in passive optical network using subcarrier allocation algorithm

Data consumption increased sharply, all triple play services such as Voice, Data-Internet & Video can be performed on one communication path, even fiber optic has also bandwidth limitations, previous studies tried to maintain the fairness among the users, but there is no fairness of service therefore the allocation of data transmission must be optimized as their needs. A Passive Optical Communication in downstream direction are presented. We proposed to modify current burst methods to scheduling distribution SC on system OFDM from OLT to ONU by utilize FDMA to allocating SubCarrier based on the services are applied. Significant gain of bandwidth efficiency up to 60% obtained when link is being congest.
