摘要

The fiber optic communication is the one where the wired and the wireless communication systems are integrated to have high bandwidth, low cost, and high data rate with high user density. The RoF technology brings about high-performance network and the guaranteed quality of service for the increased demand for multimedia services. The RoF faces problems like distortion and chromatic dispersion in the RoF link, reducing the quality of the signal at receiver. To enhance the quality of the signal at the receiver side, several techniques have been reported. Those techniques concentrated on the RoF link and the modulation schemes used in the technology. This article reviews the complete RoF technology, which includes the challenges that limit the RoF network along with its compensation scheme and the RoF in the PON services with security. Along with that, the comparative study on the problems faced by the RoF and its mitigation schemes, such as linearization techniques and compensation for chromatic dispersion, are discussed. The linearization schemes will analyze the different pre-distortion circuits used to linearize the transmitting signal such that the signal received by the mobile unit is free of distortion. When these problems are reduced, the RoF with PON has faced another major problem of insecure transmission. Hence the performance of the existing encryption schemes is compared.
